131-671: As a paper-based medium, the VVPAT offers some fundamental advantages over an electronic-only recording medium when storing votes. A paper VVPAT is readable by the human eye and voters can directly interpret their vote. Computer memory requires a device and software which is potentially proprietary . Insecure voting machine records could potentially be changed quickly without detection by the voting machine itself. Auditable paper ballots make it more difficult for voting machines to corrupt records without human intervention. Corrupt or malfunctioning voting machines might store votes other than as intended by

262-637: A storage hierarchy , which puts fast but expensive and small storage options close to the CPU and slower but less expensive and larger options further away. Generally, the fast technologies are referred to as "memory", while slower persistent technologies are referred to as "storage". Even the first computer designs, Charles Babbage 's Analytical Engine and Percy Ludgate 's Analytical Machine, clearly distinguished between processing and memory (Babbage stored numbers as rotations of gears, while Ludgate stored numbers as displacements of rods in shuttles). This distinction

393-399: A 1 kiloton of TNT (4.2 TJ) nuclear bomb dropped on Frenchman Flat on January 27, 1951. The last atmospheric test was conducted on July 17, 1962, and the underground testing of weapons continued until September 23, 1992. The location is known for having the highest concentration of nuclear-detonated weapons in the U.S. Over 80% of the state's area is owned by the federal government. This

524-402: A U.S. state, just behind Arizona's 128 °F (53 °C) reading and California's 134 °F (57 °C) reading. The vegetation of Nevada is diverse and differs by state area. Nevada contains six biotic zones : alpine , sub-alpine , ponderosa pine , pinion-juniper , sagebrush and creosotebush . Nevada is divided into political jurisdictions designated as counties . Carson City

655-502: A VVPAT system can cause it to intentionally misrecord the voter's selections. This attack could minimize detection by manipulating only a small percentage of the votes or for only lesser known races. Another security concern is that a VVPAT could print while no voter is observing the paper trail, a form of ballot stuffing . Even if additional votes were discovered through matching to the voters list, it would be impossible to identify legitimate ballots from fraudulent ballots. Alternatively

786-475: A bit pattern to each character , digit , or multimedia object. Many standards exist for encoding (e.g. character encodings like ASCII , image encodings like JPEG , and video encodings like MPEG-4 ). By adding bits to each encoded unit, redundancy allows the computer to detect errors in coded data and correct them based on mathematical algorithms. Errors generally occur in low probabilities due to random bit value flipping, or "physical bit fatigue", loss of

917-461: A built-in-hood on top of the contrast sensor and paper roll that does not soak humidity in all VVPATs to prevent it from excess light and heat. In case of a discrepancy between the information on VVPATs and the EVMs , the paper slips of the particular polling station in question are recounted. If the discrepancy persists, the count established by the VVPAT paper slips prevails over the vote count registered on

1048-493: A computer a brief window of time to move information from primary volatile storage into non-volatile storage before the batteries are exhausted. Some systems, for example EMC Symmetrix , have integrated batteries that maintain volatile storage for several minutes. Utilities such as hdparm and sar can be used to measure IO performance in Linux. Full disk encryption , volume and virtual disk encryption, andor file/folder encryption

1179-580: A county in 1856 by Utah Territorial Legislature and again in 1861 by the new Nevada Legislature. Clark County is the most populous county in Nevada, accounting for nearly three-quarters of its residents. Las Vegas, Nevada's most populous city, has been the county seat since the county was created in 1909 from a portion of Lincoln County, Nevada . Before that, it was a part of Arizona Territory. Clark County attracts numerous tourists: An estimated 44   million people visited Clark County in 2014. Washoe County

1310-424: A database) to represent a string of bits by a shorter bit string ("compress") and reconstruct the original string ("decompress") when needed. This utilizes substantially less storage (tens of percent) for many types of data at the cost of more computation (compress and decompress when needed). Analysis of the trade-off between storage cost saving and costs of related computations and possible delays in data availability

1441-468: A deterrent to voting. In addition, a VVPAT component may not be easily usable by poll-workers , many of whom are already struggling with DRE maintenance and use and new elections law requirements. In the 2006 primary election in Cuyahoga County, Ohio, a study found that 9.6 percent of the VVPAT tapes were either destroyed, blank, illegible, missing, taped together or otherwise compromised. In one case

1572-702: A drive. When the computer has finished reading the information, the robotic arm will return the medium to its place in the library. Tertiary storage is also known as nearline storage because it is "near to online". The formal distinction between online, nearline, and offline storage is: For example, always-on spinning hard disk drives are online storage, while spinning drives that spin down automatically, such as in massive arrays of idle disks ( MAID ), are nearline storage. Removable media such as tape cartridges that can be automatically loaded, as in tape libraries , are nearline storage, while tape cartridges that must be manually loaded are offline storage. Off-line storage

1703-400: A legal ballot and therefore provide a means by which a manual vote count can be conducted if a recount is necessary. In non-document ballot voting systems – both mechanical voting machines and DRE voting machines – the voter does not have an option to review a tangible ballot to confirm the voting system accurately recorded his or her intent. In addition, an election official

1834-413: A mechanical check for the tickets [ballots], while the ticket is also a check upon the register [mechanical vote counter]." This check is only effective if there is an audit to compare the paper and mechanical records. The idea of creating a parallel paper trail for a direct-recording voting mechanism remained dormant for a century until it was rediscovered by Rebecca Mercuri , who suggested essentially

1965-422: A paper ballot and disfavoring systems that use retrofitted VVPAT attachments. He has said on his personal blog that "after four years of studying the issue, I now believe that a DRE with a VVPAT is not a reasonable voting system." An auditable system, such as that provided with VVPAT, can be used in randomized recounts to detect possible malfunction or fraud. With the VVPAT method, the paper ballot can be treated as

2096-425: A paper trail cannot improve that record." In Brazil in 2003, where a small number of precincts had installed paper trails, failure of the printers delayed voters by as much as 12 hours, a figure that would be catastrophic in the U.S. Current implementation of VVPAT systems use thermal printers to print their paper ballot records. Ballot records printed on the thermal paper will fade with time. Also, heat applied to

2227-559: A piece of paper alone in a manner that is either independent or private. Nor can an individual who has a mobility disability, such as hand limitations, verify a piece of paper alone, if that individual is required to pick up and handle the paper." VVPAT systems can also introduce increased concern over reliability. Professor Michael Shamos points out that "Adding a paper printing device to a DRE machine naturally adds another component that can fail, run out of ink, jam or run out of paper. If DREs are alleged already to be prone to failure, adding

2358-408: A population of 3,104,614 at the 2020 U.S. census . In 2022, the estimated population of Nevada was 3,177,772, an increase of 73,158 residents (2.36%) since the 2020 census . Nevada had the highest percentage growth in population from 2017 to 2018. At the 2020 census, 6.0% of the state's population were reported as under 5, 22.5% were under 18, and 16.1% were 65 or older. Females made up about 49.8% of

2489-459: A potential state to have in order to become a state. At the time, Nevada's population was little more than 40,000. Governor Nye was frustrated that previous attempts to send the constitution via overland mail and by sea had failed by October 24, so on October 26 the full text was sent by telegraph at a cost of $ 4,303.27  – the most costly telegraph on file at the time for a single dispatch, equivalent to $ 83,831.36 in 2023. Finally,

2620-475: A proof of concept for this theory. Via a public records request, the two extracted voter identification from pollbooks, and voter preference from VVPATs, for a Delaware County, Ohio , precinct with multiple voting machines. Because both sets of records independently established the order of electronic ballots cast, they directly linked a voter's identification to his or her preference. Over 1.4 million registered voters in ten Ohio counties were affected. The situation

2751-476: A question from Rhode Island Governor Charles W. Lippitt about the legality of using the newly-developed McTammany direct-recording voting machine , Associate Justice Horatio Rogers of the Rhode Island Supreme Court noted that a voter casting a vote on such a machine without a written record "has no knowledge through his senses that he has accomplished a result. The most that can be said, is, if

2882-400: A relatively simple processor may keep state between successive computations to build up complex procedural results. Most modern computers are von Neumann machines. A modern digital computer represents data using the binary numeral system . Text, numbers, pictures, audio, and nearly any other form of information can be converted into a string of bits , or binary digits, each of which has

3013-638: A reliable method to verify the results during the intense scrutiny of the 2020 election. A survey by the Center for Election Innovation & Research conducted before and after the election found a smaller-than-expected drop in Georgia voters' confidence (from 90% in October 2020 to 85% in January 2021) that their votes would count as intended. Various technologies can be used to implement a paper audit trail. Systems that allow

3144-722: A single roll of paper. Voter-verifiable paper audit trail was first used in an election in India in September 2013 in Noksen (Assembly Constituency) in Nagaland. The VVPAT system was introduced in 8 of 543 parliamentary constituencies as a pilot project in the 2014 Indian general election . VVPAT was implemented in Lucknow , Gandhinagar , Bangalore South , Chennai Central , Jadavpur , Raipur , Patna Sahib and Mizoram constituencies. VVPAT along with EVMs

3275-574: A source to read instructions from, in order to start the computer. Hence, non-volatile primary storage containing a small startup program ( BIOS ) is used to bootstrap the computer, that is, to read a larger program from non-volatile secondary storage to RAM and start to execute it. A non-volatile technology used for this purpose is called ROM, for read-only memory (the terminology may be somewhat confusing as most ROM types are also capable of random access ). Many types of "ROM" are not literally read only , as updates to them are possible; however it

3406-692: A state boundary at just over 400 miles (640 km). This line begins in Lake Tahoe nearly 4 miles (6.4 km) offshore (in the direction of the boundary), and continues to the Colorado River where the Nevada, California, and Arizona boundaries merge 12 miles (19 km) southwest of the Laughlin Bridge. The largest mountain range in the southern portion of the state is the Spring Mountain Range , just west of Las Vegas. The state's lowest point

3537-490: A value of 0 or 1. The most common unit of storage is the byte , equal to 8 bits. A piece of information can be handled by any computer or device whose storage space is large enough to accommodate the binary representation of the piece of information , or simply data . For example, the complete works of Shakespeare , about 1250 pages in print, can be stored in about five megabytes (40 million bits) with one byte per character. Data are encoded by assigning

3668-595: Is Carson City . Las Vegas is the largest city in the state. Nevada is officially known as the "Silver State" because of the importance of silver to its history and economy. It is also known as the "Battle Born State" because it campaigned during its relatively brief territorial status as the Nevada Territory (1861–1864), then quickly achieved statehood during the American Civil War (1861–1865), (the words "Battle Born" also appear on its state flag ); due to

3799-419: Is open central [ä] , whereas American English /ɑː/ varies from back [ɑː] to central [äː] ), it is not the pronunciation used by Nevadans. State Assemblyman Harry Mortenson proposed a bill to recognize the alternative pronunciation of Nevada, though the bill was not supported by most legislators and never received a vote. The Nevadan pronunciation is the one used by the state legislature. At one time,

3930-462: Is "in a different format than the ballot, in a different place, is verified at a different time, and has a different graphical layout with different contrast and lighting parameters." In November 2003 in Wilton, CT, virtually all voters had to be prompted to find and verify their receipt, increasing the time required to vote and the work for the pollworkers. The VVPAT adds to the complexity of voting, already

4061-427: Is a form of volatile memory that also requires the stored information to be periodically reread and rewritten, or refreshed , otherwise it would vanish. Static random-access memory is a form of volatile memory similar to DRAM with the exception that it never needs to be refreshed as long as power is applied; it loses its content when the power supply is lost. An uninterruptible power supply (UPS) can be used to give

4192-425: Is a level below secondary storage. Typically, it involves a robotic mechanism which will mount (insert) and dismount removable mass storage media into a storage device according to the system's demands; such data are often copied to secondary storage before use. It is primarily used for archiving rarely accessed information since it is much slower than secondary storage (e.g. 5–60 seconds vs. 1–10 milliseconds). This

4323-606: Is almost entirely within the Basin and Range Province and is broken up by many north–south mountain ranges. Most of these ranges have endorheic valleys between them. Much of the northern part of the state is within the Great Basin , a mild desert that experiences hot temperatures in the summer and cold temperatures in the winter. Occasionally, moisture from the Arizona Monsoon will cause summer thunderstorms; Pacific storms may blanket

4454-523: Is along the Colorado River, south of Laughlin. Nevada has 172 mountain summits with 2,000 feet (610 m) of prominence. Nevada ranks second, after Alaska, for the greatest number of mountains in the United States, followed by California, Montana, and Washington. Nevada is the driest state in the United States. It is made up of mostly desert and semi-arid climate regions, and, with the exception of

4585-510: Is also used for secondary storage in various advanced electronic devices and specialized computers that are designed for them. Nevada Nevada ( / n ə ˈ v æ d ə , - v ɑː -/ nə- VAD -ə, -⁠ VAH - , Spanish: [neˈβaða] ) is a landlocked state in the Western region of the United States . It borders Oregon to the northwest, Idaho to

4716-410: Is computer data storage on a medium or a device that is not under the control of a processing unit . The medium is recorded, usually in a secondary or tertiary storage device, and then physically removed or disconnected. It must be inserted or connected by a human operator before a computer can access it again. Unlike tertiary storage, it cannot be accessed without human interaction. Off-line storage

4847-408: Is done before deciding whether to keep certain data compressed or not. For security reasons , certain types of data (e.g. credit card information) may be kept encrypted in storage to prevent the possibility of unauthorized information reconstruction from chunks of storage snapshots. Generally, the lower a storage is in the hierarchy, the lesser its bandwidth and the greater its access latency

4978-609: Is estimable using S.M.A.R.T. diagnostic data that includes the hours of operation and the count of spin-ups, though its reliability is disputed. Flash storage may experience downspiking transfer rates as a result of accumulating errors, which the flash memory controller attempts to correct. The health of optical media can be determined by measuring correctable minor errors , of which high counts signify deteriorating and/or low-quality media. Too many consecutive minor errors can lead to data corruption. Not all vendors and models of optical drives support error scanning. As of 2011 ,

5109-1063: Is from the CPU. This traditional division of storage to primary, secondary, tertiary, and off-line storage is also guided by cost per bit. In contemporary usage, memory is usually fast but temporary semiconductor read-write memory , typically DRAM (dynamic RAM) or other such devices. Storage consists of storage devices and their media not directly accessible by the CPU ( secondary or tertiary storage ), typically hard disk drives , optical disc drives, and other devices slower than RAM but non-volatile (retaining contents when powered down). Historically, memory has, depending on technology, been called central memory , core memory , core storage , drum , main memory , real storage , or internal memory . Meanwhile, slower persistent storage devices have been referred to as secondary storage , external memory , or auxiliary/peripheral storage . Primary storage (also known as main memory , internal memory , or prime memory ), often referred to simply as memory ,

5240-400: Is mainly because homesteads were not permitted in large enough sizes to be viable in the arid conditions that prevail throughout desert Nevada. Instead, early settlers would homestead land surrounding a water source, and then graze livestock on the adjacent public land, which is useless for agriculture without access to water (this pattern of ranching still prevails). The COVID-19 pandemic

5371-458: Is more difficult than counting standard paper ballots or even punch cards . DRE VVPAT systems that print the ballot records out in the order in which they were cast (often known as reel-to-reel systems) raise privacy issues, if the order of voting can also be recorded. VVPAT printers that cut the paper after each ballot to form individual ballots can avoid this concern. If there are multiple voting machines it would be more difficult to match between

5502-442: Is officially a consolidated municipality, meaning it legally functions as both a city and a county. As of 1919, there were 17 counties in the state, ranging from 146 to 18,159 square miles (380 to 47,030 km ). Lake County , one of the original nine counties formed in 1861, was renamed Roop County in 1862. Part of the county became Lassen County, California , in 1864, resolving border uncertainty. In 1883, Washoe County annexed

5633-416: Is primarily useful for extraordinarily large data stores, accessed without human operators. Typical examples include tape libraries and optical jukeboxes . When a computer needs to read information from the tertiary storage, it will first consult a catalog database to determine which tape or disc contains the information. Next, the computer will instruct a robotic arm to fetch the medium and place it in

5764-700: Is readily available for most storage devices. Hardware memory encryption is available in Intel Architecture, supporting Total Memory Encryption (TME) and page granular memory encryption with multiple keys (MKTME). and in SPARC M7 generation since October 2015. Distinct types of data storage have different points of failure and various methods of predictive failure analysis . Vulnerabilities that can instantly lead to total loss are head crashing on mechanical hard drives and failure of electronic components on flash storage. Impending failure on hard disk drives

5895-488: Is slow and memory must be erased in large portions before it can be re-written. Some embedded systems run programs directly from ROM (or similar), because such programs are rarely changed. Standard computers do not store non-rudimentary programs in ROM, and rather, use large capacities of secondary storage, which is non-volatile as well, and not as costly. Recently, primary storage and secondary storage in some uses refer to what

6026-457: Is the fourth-largest producer of gold in the world. Nevada is the driest state, and has been influenced by climate change , droughts in Nevada have been increasing in frequency and severity, putting a further strain on Nevada's water security . The name "Nevada" comes from the Spanish adjective nevada ( [neˈβaða] ), meaning "snow-covered" or "snowy". The state takes its name from

6157-442: Is the only one directly accessible to the CPU. The CPU continuously reads instructions stored there and executes them as required. Any data actively operated on is also stored there in a uniform manner. Historically, early computers used delay lines , Williams tubes , or rotating magnetic drums as primary storage. By 1954, those unreliable methods were mostly replaced by magnetic-core memory . Core memory remained dominant until

6288-664: Is the second-most populous county of Nevada. Its county seat is Reno . Washoe County includes the Reno–Sparks metropolitan area . Lyon County is the third most populous county. It was one of the nine original counties created in 1861. It was named after Nathaniel Lyon , the first Union General to be killed in the Civil War . Its current county seat is Yerington . Its first county seat was established at Dayton on November 29, 1861. There are 68 designated wilderness areas in Nevada, protecting some 6,579,014 acres (2,662,433 ha) under

6419-405: Is typically automatically fenced out, taken out of use by the device, and replaced with another functioning equivalent group in the device, where the corrected bit values are restored (if possible). The cyclic redundancy check (CRC) method is typically used in communications and storage for error detection . A detected error is then retried. Data compression methods allow in many cases (such as

6550-505: Is typically measured in milliseconds (thousandths of a second), while the access time per byte for primary storage is measured in nanoseconds (billionths of a second). Thus, secondary storage is significantly slower than primary storage. Rotating optical storage devices, such as CD and DVD drives, have even longer access times. Other examples of secondary storage technologies include USB flash drives , floppy disks , magnetic tape , paper tape , punched cards , and RAM disks . Once

6681-412: Is unable to manually recount ballots in the event of a dispute. Because of this, critics claim there is an increased chance for electoral fraud or malfunction and security experts, such as Bruce Schneier , have demanded voter-verifiable paper audit trails. Non-document ballot voting systems allow only a recount of the "stored votes". These "stored votes" might not represent the correct voter intent if

6812-496: Is used to transfer information since the detached medium can easily be physically transported. Additionally, it is useful for cases of disaster, where, for example, a fire destroys the original data, a medium in a remote location will be unaffected, enabling disaster recovery . Off-line storage increases general information security since it is physically inaccessible from a computer, and data confidentiality or integrity cannot be affected by computer-based attack techniques. Also, if

6943-648: The EVMs . Common VVPAT problems are: Other hurdles in the implementation of paper audit trails include the performance and authority of the audit. Paper audit systems increase the cost of electronic voting systems, can be difficult to implement, often require specialized external hardware, and can be difficult to use. In the United States twenty-seven states require a paper audit trail by statute or regulation for all direct recording electronic voting machines used in public elections . Another eighteen States don't require them, but use them either statewide or in local jurisdictions. The introduction of malicious software into

All of these rivers are endorheic basins , ending in Walker Lake , Pyramid Lake , and the Carson Sink , respectively. However, not all of Nevada is within the Great Basin. Tributaries of the Snake River drain the far north, while the Colorado River , which also forms much of

7205-483: The Las Vegas Valley , the average summer diurnal temperature range approaches 40 °F (22 °C) in much of the state. While winters in northern Nevada are long and fairly cold, the winter season in the southern part of the state tends to be of short duration and mild. Most parts of Nevada receive scarce precipitation during the year. The most rain that falls in the state falls on the east and northeast slopes of

The discovery of mineral wealth at the Comstock Lode silver bonanza in 1859 led to a population boom similar to that of earlier California Gold Rush in 1848–1852, that became an impetus to the creation of the Nevada Territory out of the western portion of the Utah Territory in 1861. Nevada became the 36th state on October 31, 1864, as the second of two states added to

The first Europeans to explore the region were tho Spanish and explorers from their worldwide Spanish Empire in the 16th century . They called the region Nevada (snowy) because of the snow which covered the mountains in winter, similar to the Sierra Nevada mountains in European Spain . The area formed from mostly Alta California (Upper California) to

It is also known as the " Sagebrush State", for the native plant of the same name; and as the " Sage-hen State". The state's name means "snowy" in the Spanish language , referring to Nevada's small overlap with the Sierra Nevada mountain range on its western edge; however,

8646-690: The 1970s, when advances in integrated circuit technology allowed semiconductor memory to become economically competitive. This led to modern random-access memory (RAM). It is small-sized, light, but quite expensive at the same time. The particular types of RAM used for primary storage are volatile , meaning that they lose the information when not powered. Besides storing opened programs, it serves as disk cache and write buffer to improve both reading and writing performance. Operating systems borrow RAM capacity for caching so long as it's not needed by running software. Spare memory can be utilized as RAM drive for temporary high-speed data storage. As shown in

The terrain is also lower, mostly below 4,000 feet (1,200 m), creating conditions for hot summer days and cool to chilly winter nights. Nevada and California have by far the longest diagonal line (in respect to the cardinal directions) as

9170-614: The Nevada Territory separated from the Utah Territory and adopted its current name, shortened from The Sierra Nevada (Spanish for "snow-covered mountain range"). The 1861 southern boundary is commemorated by Nevada Historical Markers 57 and 58 in Lincoln and Nye counties. Eight days before the presidential election of 1864 , Nevada became the 36th state in the Union, despite lacking the minimum 60,000 residents that Congress typically required

9301-620: The Republicans won the election handily and did not need Nevada's help. Nevada is one of only two states to significantly expand its borders after admission to the Union, with the other being Missouri , which acquired additional territory in 1837 due to the Platte Purchase . In 1866 another part of the western Utah Territory was added to Nevada in the eastern part of the state, setting the current eastern boundary. Nevada achieved its current southern boundaries on January 18, 1867, when it absorbed

9432-473: The Union during the Civil War (the first being West Virginia ). Nevada is known for its libertarian laws. In 1940, with a population of just over 110,000 people, Nevada was by far the least-populated state, with less than half the population of the next least-populous state, Wyoming . However, legalized gambling and lenient marriage and divorce laws transformed Nevada into a major tourist destination in

9563-623: The United States continued to be administered as territories. As part of the Mexican Cession (1848) and the subsequent California Gold Rush that used Emigrant Trails through the area, the state's area evolved first as part of the Utah Territory and New Mexico Territory , then the Nevada Territory (March 2, 1861; named for the Sierra Nevada ). The first discovery of a major U.S. deposit of silver ore occurred in Comstock Lode under Virginia City, Nevada , in 1859. On March 2, 1861,

9694-559: The VVPAT does not serve as an effective check on malfunction or fraud unless a statistically relevant number of voters participate. Current VVPAT systems are not usable by some disabled voters. Senator Christopher Dodd (D-CT) testified before the United States Senate Committee on Rules and Administration at a June 2005 hearing on Voter Verification in Federal Elections "The blind cannot verify their choices by means of

9825-560: The VeriVote Printer. Avante's system saw its first trial use in 2002, and in 2003, the state of Nevada required the use of VVPAT technology statewide and adopted the Sequoia system. It is notable that, in Avante's design, the shield preventing the voter from taking the paper record was an afterthought, while in Sequoia's design, the paper record for successive voters were printed sequentially on

9956-514: The area with snow. The state's highest recorded temperature was 125 °F (52 °C) in Laughlin (elevation of 605 feet or 184 meters) on June 29, 1994. The coldest recorded temperature was −52  °F (−47  °C ) set in San Jacinto in 1972, in the northeastern portion of the state. The Humboldt River crosses the state from east to west across the northern part of the state, draining into

10087-442: The authority question remains unclear. Computer storage Computer data storage or digital data storage is a technology consisting of computer components and recording media that are used to retain digital data . It is a core function and fundamental component of computers. The central processing unit (CPU) of a computer is what manipulates data by performing computations. In practice, almost all computers use

10218-413: The boundary with Arizona , drains much of southern Nevada. The mountain ranges, some of which have peaks above 13,000 feet (4,000 m), harbor lush forests high above desert plains, creating sky islands for endemic species. The valleys are often no lower in elevation than 3,000 feet (910 m), while some in central Nevada are above 6,000 feet (1,800 m). The southern third of the state, where

10349-524: The concept of virtual memory , allowing the utilization of more primary storage capacity than is physically available in the system. As the primary memory fills up, the system moves the least-used chunks ( pages ) to a swap file or page file on secondary storage, retrieving them later when needed. If a lot of pages are moved to slower secondary storage, the system performance is degraded. The secondary storage, including HDD , ODD and SSD , are usually block-addressable. Tertiary storage or tertiary memory

10480-574: The democracy." In India, in an instance VVPAT was helpful in resolving an issue pertaining to a tally of votes in Kancheepuram (State Assembly Constituency) in 2016 Tamil Nadu Legislative Assembly election as the number of votes entered in the Form 17C of a polling booth and the total number of votes recorded in the EVM control unit of that booth did not tally. In June 2018, Election Commission of India introduced

10611-430: The desired data to primary storage. Secondary storage is non-volatile (retaining data when its power is shut off). Modern computer systems typically have two orders of magnitude more secondary storage than primary storage because secondary storage is less expensive. In modern computers, hard disk drives (HDDs) or solid-state drives (SSDs) are usually used as secondary storage. The access time per byte for HDDs or SSDs

10742-491: The desired location of data. Then it reads or writes the data in the memory cells using the data bus. Additionally, a memory management unit (MMU) is a small device between CPU and RAM recalculating the actual memory address, for example to provide an abstraction of virtual memory or other tasks. As the RAM types used for primary storage are volatile (uninitialized at start up), a computer containing only such storage would not have

10873-435: The developer of the original Australian DRE system, believes that "There's no reason voters should trust a system that doesn't have [a voter-verified audit trail], and they shouldn't be asked to. Why on earth should [voters] have to trust me – someone with a vested interest in the project's success? A voter-verified audit trail is the only way to 'prove' the system's integrity to the vast majority of electors, who after all, own

11004-400: The diagram, traditionally there are two more sub-layers of the primary storage, besides main large-capacity RAM: Main memory is directly or indirectly connected to the central processing unit via a memory bus . It is actually two buses (not on the diagram): an address bus and a data bus . The CPU firstly sends a number through an address bus, a number called memory address , that indicates

11135-427: The election or only in the event of a dispute. In the event an audit is performed after the election and a discrepancy is discovered between the ballot count and the audit count it is unclear which count is the authoritative count. Some jurisdictions have statutorily defined the ballot as the authoritative count leaving the role of an audit in question. Because VVPAT is a recent addition to direct record voting systems

11266-484: The federal government presented the $ 49   million construction contract for Boulder Dam (now Hoover Dam ). The Nevada Test Site , 65 miles (105 km) northwest of the city of Las Vegas, was founded on January 11, 1951, for the testing of nuclear weapons . The site consists of about 1,350 square miles (3,500 km ) of the desert and mountainous terrain. Nuclear testing at the Nevada Test Site began with

11397-437: The final vote count and refuting claims by President Trump in a January 2, 2021 phone call with Georgia Secretary of State Brad Raffensperger that the count was inaccurate. In additional to providing transparency, Georgia's new VVPAT system helped counter a strong disinformation campaign by facilitating a total of three cross-confirming counts—initial vote, audit, and hand recount. This increased voter confidence, providing

11528-419: The first permanent structure, a 150-foot square adobe fort , northeast of downtown Las Vegas, converging on the Spanish and Mormon Roads . The fort remained under Salt Lake City 's control until the winter of 1858–1859, and the route remained largely under the control of Salt Lake City and Santa Fe tradespersons. As such, these pioneers laid the foundation for the emergence of the initial settlements between

11659-421: The first phase of its reopening on May 9, 2020. Restaurants, retailers, outdoor malls, and hair salons were among the businesses allowed to reopen, but with precautions in place, such as limiting occupancy to 50 percent. A second phase went into effect on May 29, 2020. It allowed for the reopening of state parks and businesses such as bars, gyms, and movie theaters. Casinos began reopening on June 4, 2020. Nevada

11790-477: The former using standard MOSFETs and the latter using floating-gate MOSFETs . In modern computers, primary storage almost exclusively consists of dynamic volatile semiconductor random-access memory (RAM), particularly dynamic random-access memory (DRAM). Since the turn of the century, a type of non-volatile floating-gate semiconductor memory known as flash memory has steadily gained share as off-line storage for home computers. Non-volatile semiconductor memory

11921-500: The full voter list and the VVPATs. Alternatively, an attacker could watch the order in which people use a particular voting system and note the order of each particular vote he is interested in. If that attacker later obtains the paper ballot records she could compare the two and compromise the privacy of the ballot. This could also lead to vote selling and voter intimidation . In 2007, Jim Cropcho and James Moyer executed and publicized

12052-568: The information stored for archival purposes is rarely accessed, off-line storage is less expensive than tertiary storage. In modern personal computers, most secondary and tertiary storage media are also used for off-line storage. Optical discs and flash memory devices are the most popular, and to a much lesser extent removable hard disk drives; older examples include floppy disks and Zip disks. In enterprise uses, magnetic tape cartridges are predominant; older examples include open-reel magnetic tape and punched cards. Storage technologies at all levels of

12183-476: The introduction of a new voting system that includes a VVPAT component would have less implementation challenges. Some implementations of the VVPAT place a high cognitive burden on the voter and are extraordinarily error prone. One important question of VVPAT systems is regarding the time of the audit. Some have suggested that random audits of direct recording electronic voting machines be performed on Election Day to protect against machine malfunction. However,

12314-603: The jurisdiction of the National Park Service , U.S. Forest Service , and Bureau of Land Management . The Nevada state parks comprise protected areas managed by the state of Nevada, including state parks , state historic sites , and state recreation areas . There are 24 state park units, including Van Sickle Bi-State Park which opened in July 2011 and is operated in partnership with the adjacent state of California . The United States Census Bureau determined Nevada had

12445-460: The machine has been corrupted or suffered malfunction. As of 2024, VVPAT systems are used in countries including the United States, India, Venezuela, the Philippines, and Bulgaria. In the U.S., 98.5 percent of registered voters live in jurisdictions offering some form of paper ballot, whether hand-marked or VVPAT. Only 1.4 percent use electronic systems with no paper record. In 1897, responding to

12576-437: The machine worked as intended, then he ... has voted." This observation remains at the center of concerns with ballotless DRE voting machines today. In 1899, Joseph Gray addressed this problem with a mechanical voting machine that simultaneously recorded votes in its mechanism and punched those votes on a paper ballot that the voter could inspect before dropping it in a ballot box . Gray explained that "in this manner, we have

12707-641: The most commonly used data storage media are semiconductor, magnetic, and optical, while paper still sees some limited usage. Some other fundamental storage technologies, such as all-flash arrays (AFAs) are proposed for development. Semiconductor memory uses semiconductor -based integrated circuit (IC) chips to store information. Data are typically stored in metal–oxide–semiconductor (MOS) memory cells . A semiconductor memory chip may contain millions of memory cells, consisting of tiny MOS field-effect transistors (MOSFETs) and/or MOS capacitors . Both volatile and non-volatile forms of semiconductor memory exist,

12838-536: The northeast, California to the west, Arizona to the southeast, and Utah to the east. Nevada is the seventh-most extensive , the 32nd-most populous , and the ninth-least densely populated U.S. state. Nearly three-quarters of Nevada's population live in Clark County , which contains the Las Vegas–Paradise metropolitan area , including three of the state's four largest incorporated cities. Nevada's capital

12969-465: The official ballot of record. In this scenario, the ballot is primary and the electronic records are used only for an initial count or, in some cases, if the VVPAT is damaged or otherwise unreadable. In any subsequent recounts or challenges the paper, not the electronic ballot, would be used for tabulation. Whenever a paper record serves as the legal ballot, that system will be subject to the same benefits and concerns of any paper ballot system. Matt Quinn,

13100-434: The paper before or after the election can destroy the printing. It can be significantly more difficult to implement a VVPAT as an after-the-fact feature. For jurisdictions currently using DRE voting machines that lack a VVPAT, implementation can be expensive to add and difficult to implement due to the specialized external hardware required. To add a VVPAT component to a DRE machine, a jurisdiction would be required to purchase

13231-565: The partial tallying of votes before the polls have closed could create a problem similar to the occurrence in American national elections where a winner is declared based on East Coast results long before polls have closed on the West Coast. In addition, the partial tallying of votes before the polls have closed may be illegal in some jurisdictions. Others have suggested that random audits of direct recording electronic voting machines be performed after

13362-578: The period described in Roughing It , mining had led to an industry of speculation and immense wealth. Both mining and population temporarily declined in the late 19th century. However, the rich silver strike at Tonopah in 1900, followed by strikes in Goldfield and Rhyolite , created a second mining boom in Nevada and Nevada's population. Unregulated gambling was commonplace in the early Nevada mining towns but

13493-408: The physical bit in the storage of its ability to maintain a distinguishable value (0 or 1), or due to errors in inter or intra-computer communication. A random bit flip (e.g. due to random radiation ) is typically corrected upon detection. A bit or a group of malfunctioning physical bits (the specific defective bit is not always known; group definition depends on the specific storage device)

13624-430: The population. 19.1% of the population was reported as foreign-born. Since the 2020 census, the population of Nevada had a natural increase of 2,374 (the net difference between 42,076 births and 39,702 deaths); and an increase due to net migration of 36,605 (of which 34,280 was due to domestic and 2,325 was due to international migration). The center of population of Nevada is in southern Nye County . In this county,

13755-583: The portion of Pah-Ute County in the Arizona Territory west of the Colorado River, essentially all of present-day Nevada south of the 37th parallel . The transfer was prompted by the discovery of gold in the area, and officials thought Nevada would be better able to oversee the expected population boom. This area includes most of what is now Clark County and the Las Vegas metropolitan area. Mining shaped Nevada's economy for many years (see Silver mining in Nevada ). When Mark Twain lived in Nevada during

13886-531: The portion that remained in Nevada. In 1969, Ormsby County was dissolved and the Consolidated Municipality of Carson City was created by the Legislature in its place coterminous with the old boundaries of Ormsby County. Bullfrog County was formed in 1987 from part of Nye County. After the creation was declared unconstitutional, the county was abolished in 1989. Humboldt County was designated as

14017-406: The printer could invalidate the printed record after the voter leaves and print a new fraudulent ballot. These ballots would be undetectable as invalidated ballots are quite common during elections. Also, VVPAT systems that are technically able to reverse the paper feed could be open to manipulated software overwriting or altering the VVPAT after the voter checks it. For the voter, the printed record

14148-595: The province of Alta California became a territory (state) of Mexico, with a small population. Jedediah Smith entered the Las Vegas Valley in 1827, Peter Skene Ogden traveled the Humboldt River in 1828, and in 1829 a merchant from Nuevo México named Antonio Armijo streamlined travel along the Old Spanish Trail . Chronicling Armijo's route his scout Raphael Rivera was the first to name Las Vegas, in an 1830 report to governor José Antonio Chaves . Following

14279-475: The response from Washington came on October 31, 1864: "the pain is over, the child is born, Nevada this day was admitted into the Union". Statehood was rushed to the date of October 31 to help ensure Abraham Lincoln 's reelection on November   8 and post-Civil War Republican dominance in Congress, as Nevada's mining-based economy tied it to the more industrialized Union . As it turned out, however, Lincoln and

14410-457: The rest of Nevada is largely desert and semi-arid , much of it within the central Great Basin region. Areas south of the Great Basin are within the Mojave Desert shared with Southern California , while the high altitude of Lake Tahoe and the Sierra Nevada lie on the western edge. In 2020, 80.1% of the state's land was managed by various jurisdictions of the U.S. federal government , both civilian and military. Native Americans of mostly

14541-530: The result. It would have to be reconfigured to change its behavior. This is acceptable for devices such as desk calculators , digital signal processors , and other specialized devices. Von Neumann machines differ in having a memory in which they store their operating instructions and data. Such computers are more versatile in that they do not need to have their hardware reconfigured for each new program, but can simply be reprogrammed with new in-memory instructions; they also tend to be simpler to design, in that

14672-529: The same idea in 1992. The Mercuri method , as some have called it, was refined in her Ph.D. dissertation in October 2000; in her final version, the paper record is printed behind glass so that the voter may not take it or alter it. The first commercial voting systems to incorporate voter verifiable paper audit trail printers were the Avante Vote Trakker and a retrofit to the Sequoia AVC Edge called

14803-419: The security and reliability of its aging electronic voting machines, Georgia officials approved a $ 107 million contract with Dominion Voting Systems to equip all 159 Georgia counties with new ballot-marking devices that provide a paper ballot for every vote cast (VVPAT). The upgrade was completed in time for the 2020 Georgia Republican and Democratic presidential primaries . The system proved critical during

14934-480: The state's official tourism organization, TravelNevada, stylized the name of the state as "Nevăda", with a breve over the a indicating the locally preferred pronunciation, which was also available as a license plate design until 2007. Before the arrival of Europeans, the earliest inhabitants were Indigenous tribes including the Goshute , Southern Paiute , Mohave , and Wašišiw ( Washoe people ). Francisco Garcés

15065-413: The storage hierarchy can be differentiated by evaluating certain core characteristics as well as measuring characteristics specific to a particular implementation. These core characteristics are volatility, mutability, accessibility, and addressability. For any particular implementation of any storage technology, the characteristics worth measuring are capacity and performance. Non-volatile memory retains

15196-422: The stored information even if not constantly supplied with electric power. It is suitable for long-term storage of information. Volatile memory requires constant power to maintain the stored information. The fastest memory technologies are volatile ones, although that is not a universal rule. Since the primary storage is required to be very fast, it predominantly uses volatile memory. Dynamic random-access memory

15327-693: The suggestions by Rivera of a spring, on the published expedition's map, located in the Las Vegas area John C. Frémont set up camp in Las Vegas Springs in 1844. In 1847, Mormons established the State of Deseret , claiming all of Nevada within the Great Basin and the Colorado watershed. They built the first permanent settlement in what is now Nevada, called Mormon Station (now Genoa), in 1851. Additionally, in June 1855, William Bringhurst and 29 other Mormon missionaries built

15458-472: The system designed by the vendor of the DRE machine with a no bid, sole source purchase contract. That assumes the vendor has designed a component that is compatible with the DRE machine in use. The vendor may not have developed a VVPAT component that is compatible with the DRE machine in use, thus requiring the jurisdiction to purchase an entirely new voting system . For jurisdictions not currently using DRE machines,

15589-437: The thermal paper was loaded into the printer backwards leaving a blank tape, which was not realized by voters who couldn't verify the paper trail. The Cuyahoga Election Review Panel proposed in its final report to remove the opaque doors covering the VVPAT except the ones equipped with equipment for blind voters. In general collecting and counting these printed records can be difficult. Records printed on continuous rolls of paper

15720-464: The unincorporated town of Pahrump , 60 miles (97 km) west of Las Vegas on the California state line, has grown very rapidly from 1980 to 2020. At the 2020 census, the town had 44,738 residents. Las Vegas grew from a gulch of 100 people in 1900 to 10,000 by 1950 to 100,000 by 1970, and was America's fastest-growing city and metropolitan area from 1960 to 2000. From about the 1940s until 2003, Nevada

15851-403: The voter unnoticed. A VVPAT allows voters to verify their votes are cast as intended, an additional barrier to changing or destroying votes. The VVPAT includes a direct recording electronic voting system (DRE), to assure voters that their votes have been recorded as intended and as a means to detect fraud and equipment malfunction. Depending on election laws, the paper audit trail may constitute

15982-544: The voters to prove how they voted do not conform to the generally accepted definition of voting by secret ballot , as such proof raises the risk of voter intimidation and vote selling . As such, systems that allow such proof are generally forbidden under the terms of numerous international agreements and domestic laws. Professor Avi Rubin has testified in front of the United States House Committee on House Administration in favor of voting systems that use

16113-490: The west and to the east as part of Nuevo México ( New Mexico )'s colonial province and territory to the northern portion within the larger colonial era Viceroyalty of New Spain , which gained freedom as the first independent government of the First Mexican Empire ( Mexico ) in 1821. The westward expanding United States a quarter-century later annexed the area of the Mexican Cession in 1849 after its victory in

16244-525: Was confirmed in Nevada on March 5, 2020. Because of concerns about coronavirus disease 2019 (COVID-19), Nevada governor Steve Sisolak declared a state of emergency on March 12, 2020. Four days later, Nevada reported its first death. On March 17, 2020, Sisolak ordered the closure of non-essential businesses in the state to help prevent the spread of the coronavirus. Various protests were held against Sisolak's shutdown order beginning in April 2020. Nevada launched

16375-461: Was extended in the Von Neumann architecture , where the CPU consists of two main parts: The control unit and the arithmetic logic unit (ALU). The former controls the flow of data between the CPU and memory, while the latter performs arithmetic and logical operations on data. Without a significant amount of memory, a computer would merely be able to perform fixed operations and immediately output

16506-399: Was followed by a full statewide hand recount of the paper ballots, which confirmed the result. Starting in 2002 with the statewide adoption of DREs and as recently as the 2016 election, the lack of a system producing auditable paper ballots would have made a recount impossible. The VVPAT system allowed officials to cross-check electronic results with paper records, confirming the accuracy of

16637-441: Was historically called, respectively, secondary storage and tertiary storage . The primary storage, including ROM , EEPROM , NOR flash , and RAM , are usually byte-addressable . Secondary storage (also known as external memory or auxiliary storage ) differs from primary storage in that it is not directly accessible by the CPU. The computer usually uses its input/output channels to access secondary storage and transfer

16768-483: Was outlawed in 1909 as part of a nationwide anti-gambling crusade. Because of subsequent declines in mining output and the decline of the agricultural sector during the Great Depression , Nevada again legalized gambling on March 19, 1931, with approval from the legislature. Governor Fred B. Balzar 's signature enacted the most liberal divorce laws in the country and open gambling. The reforms came just eight days after

16899-426: Was resolved before the next election by omitting the consecutive numbers on Authority To Vote slips from pollbook records. However, similar vulnerabilities may still exist in other states. Also problematic is that voters are not required to actually check the paper audit before casting a ballot, which is critical to "verifying" the vote. While the option to look at the paper may provide comfort to an individual voter,

17030-775: Was the first European in the area. Nevada was annexed as a part of the Spanish Empire in the northwestern territory of New Spain . Administratively, the area of Nevada was part of the Commandancy General of the Provincias Internas in the Viceroyalty of New Spain. Nevada became a part of Alta California (Upper California) province in 1804 when the Californias were split. With the Mexican War of Independence won in 1821,

17161-455: Was used on a large-scale for the first time in India, in 10 assembly seats out of 40 in 2013 Mizoram Legislative Assembly election . VVPAT -fitted EVMs was used in entire Goa state in the 2017 assembly elections , the first time that entire state in India saw the implementation of VVPAT. A VVPAT system was introduced in all 543 Lok sabha constituencies in the 2019 Indian general election . In July 2019, after legal challenges and concerns about
