Peripheral devices allow information to be retrieved from an external source, and they enable

440-419: A keyboard , and computed and printed the results, demonstrating the feasibility of an electromechanical analytical engine. During the first half of the 20th century, many scientific computing needs were met by increasingly sophisticated analog computers, which used a direct mechanical or electrical model of the problem as a basis for computation . However, these were not programmable and generally lacked

550-514: A mass-production basis, which limited them to a number of specialized applications. At the University of Manchester , a team under the leadership of Tom Kilburn designed and built a machine using the newly developed transistors instead of valves. Their first transistorized computer and the first in the world, was operational by 1953 , and a second version was completed there in April 1955. However,

660-429: A monolithic integrated circuit (IC) chip. Kilby's IC had external wire connections, which made it difficult to mass-produce. Noyce also came up with his own idea of an integrated circuit half a year later than Kilby. Noyce's invention was the first true monolithic IC chip. His chip solved many practical problems that Kilby's had not. Produced at Fairchild Semiconductor, it was made of silicon , whereas Kilby's chip

770-415: A "replacement OS" for Workbench which overlaid itself upon the system. It started as a file manager, and then became a complete desktop replacement and an alternative to the official Workbench. The utility was later ported to Windows and remains widely used.

In 1985 Commodore licensed the software called Transformer from Simile Research and put it on the market in January 1986, bundled with an external A1020 5.25-inch floppy drive . It emulated 8086 Intel -based PC-XT hardware. It could run MS-DOS and MS-DOS software such as Lotus 123 or WordStar . This provided early access to many applications, while waiting for native Amiga software to be developed . In 1985, Deluxe Paint emerged with graphic features that had been available only on dedicated graphic computers. It

1210-519: A double-density disk, but could actually read tracks 80 through 82. Standard disk-imaging software ignored these tracks, so that a duplicate of a boxed disk would not contain the key and the software would not work. A similar technique involved writing to normally-unused sectors of the disk. Copy software called "nibble" copiers appeared that could exactly reproduce such disks. Publishers turned to other methods. Hardware dongles were occasionally used for high-end software. AmigaHASP protected Rashumon and

Conventionally, a modern computer consists of at least one processing element , typically

3960-504: The "second generation" of computers. Compared to vacuum tubes, transistors have many advantages: they are smaller, and require less power than vacuum tubes, so give off less heat. Junction transistors were much more reliable than vacuum tubes and had longer, indefinite, service life. Transistorized computers could contain tens of thousands of binary logic circuits in a relatively compact space. However, early junction transistors were relatively bulky devices that were difficult to manufacture on

Alternative filesystems included AsimCDFS , AmiCDROM , CDVDFS , Allegro CDFS and CacheCDFS . BurnIt! , Frying Pan , MakeCD , AmiDVD , DVDRecord , DVDAuthor could burn CDs, DVDs and/or Blu-ray media. MakeCD

7700-473: The exact definition of the term "microprocessor", it is largely undisputed that the first single-chip microprocessor was the Intel 4004 , designed and realized by Federico Faggin with his silicon-gate MOS IC technology, along with Ted Hoff , Masatoshi Shima and Stanley Mazor at Intel . In the early 1970s, MOS IC technology enabled the integration of more than 10,000 transistors on a single chip. System on

7810-740: The file extension of " ADF " (Amiga Disk File). Actual Amiga disks cannot be used, because of limitations in the floppy controllers used in other computers. Images of Amiga formatted hard drives can also be made. UAE also supports mapping host operating system 's directories to Amiga hard drives, and finally, physical Amiga formatted hard drives can be mounted. UAE does not include the original Amiga operating system ROM and files, which are required for running an Amiga system. These are included under license in packages like Amiga Forever . Original Kickstart 3.1 ROM images are also included with AmigaOS4 for PowerPC since version 4.1 Update 4. UAE also supports alternative system ROMs, such as those derived from

7920-503: The first Colossus. After a functional test in December 1943, Colossus was shipped to Bletchley Park, where it was delivered on 18 January 1944 and attacked its first message on 5 February. Colossus was the world's first electronic digital programmable computer. It used a large number of valves (vacuum tubes). It had paper-tape input and was capable of being configured to perform a variety of boolean logical operations on its data, but it

8030-725: The first attested use of computer in the 1640s, meaning 'one who calculates'; this is an "agent noun from compute (v.)". The Online Etymology Dictionary states that the use of the term to mean " 'calculating machine' (of any type) is from 1897." The Online Etymology Dictionary indicates that the "modern use" of the term, to mean 'programmable digital electronic computer' dates from "1945 under this name; [in a] theoretical [sense] from 1937, as Turing machine ". The name has remained, although modern computers are capable of many higher-level functions. Devices have been used to aid computation for thousands of years, mostly using one-to-one correspondence with fingers . The earliest counting device

8140-409: The form of conditional branching and loops , and integrated memory , making it the first design for a general-purpose computer that could be described in modern terms as Turing-complete . The machine was about a century ahead of its time. All the parts for his machine had to be made by hand – this was a major problem for a device with thousands of parts. Eventually, the project was dissolved with

8250-415: The integrated circuit in July 1958, successfully demonstrating the first working integrated example on 12 September 1958. In his patent application of 6 February 1959, Kilby described his new device as "a body of semiconductor material ... wherein all the components of the electronic circuit are completely integrated". However, Kilby's invention was a hybrid integrated circuit (hybrid IC), rather than

8360-411: The integration. In 1876, Sir William Thomson had already discussed the possible construction of such calculators, but he had been stymied by the limited output torque of the ball-and-disk integrators . In a differential analyzer, the output of one integrator drove the input of the next integrator, or a graphing output. The torque amplifier was the advance that allowed these machines to work. Starting in

8470-566: The lead for creating the ANIM file type standard. Byte-by-Byte Software Inc. released Sculpt-3D . It was the first rendering tool available for the first time to a vast audience of public, and in October of the same year, Impulse released TurboSilver . In 1987 the Amiga 500 (A500) was released. The Amiga software market moved in favor of entertainment over professional software. ProWrite (word processor), Maxiplan 500 (spreadsheet), and Aegis Sonix ,

8580-569: The machine did make use of valves to generate its 125 kHz clock waveforms and in the circuitry to read and write on its magnetic drum memory , so it was not the first completely transistorized computer. That distinction goes to the Harwell CADET of 1955, built by the electronics division of the Atomic Energy Research Establishment at Harwell . The metal–oxide–silicon field-effect transistor (MOSFET), also known as

8690-1016: The memory bus) with the CPU, throughput increases measurably if the display is disabled. Some processor-intensive software, such as 3D renderers, disable the display during calculation to gain speed. Medusa ( Atari ST emulator), Fusion ( Macintosh Emulator), AMax and AMax II, (Macintosh), GO64 (first Commodore C64 emulator), Transformer and PCTask (it was an Intel 8088 emulator, all software based, capable to emulate Intel PC based platforms ranging from PC XT 4,7 and 7 MHz on Amiga 500 , up to 80486 running at 12 MHz on Amiga 4000 and other accelerated Amigas), A64 Package (C64), Amiga BBC Emulator ( Acorn BBC emulator) Atari ST Emulator (AtariST), Hatari (Atari ST and STE), Basilisk II (Macintosh) classic, Frodo (C64), PSXE (Sony PlayStation ), Hu-Go! ( PC Engine , TurboGrafx-16 ), FunnyMu ( Creativision , Funvision , Wizzard ), AmiArcadia ( Arcadia 2001 and VC 4000 , TVGC). VICE emulator

8800-452: The modern computer was proposed by Alan Turing in his seminal 1936 paper, On Computable Numbers . Turing proposed a simple device that he called "Universal Computing machine" and that is now known as a universal Turing machine . He proved that such a machine is capable of computing anything that is computable by executing instructions (program) stored on tape, allowing the machine to be programmable. The fundamental concept of Turing's design

8910-403: The more famous Sir William Thomson. The art of mechanical analog computing reached its zenith with the differential analyzer , built by H. L. Hazen and Vannevar Bush at MIT starting in 1927. This built on the mechanical integrators of James Thomson and the torque amplifiers invented by H. W. Nieman. A dozen of these devices were built before their obsolescence became obvious. By the 1950s,

9020-422: The past on Usenet and other public forums where people argued about the possibility of writing an Amiga emulator. Some considered UAE to be attempting the impossible; to be demanding that a system read, process and output 100 MB/s of data when the fastest PC was a 66 MHz 486 , while keeping various emulated chips (the Amiga chipset ) all in sync and appearing as they were supposed to appear to software. UAE

9130-486: The practical use of MOS transistors as memory cell storage elements, leading to the development of MOS semiconductor memory , which replaced earlier magnetic-core memory in computers. The MOSFET led to the microcomputer revolution , and became the driving force behind the computer revolution . The MOSFET is the most widely used transistor in computers, and is the fundamental building block of digital electronics . The next great advance in computing power came with

9240-571: The programming specifications and development computers to various software houses, prominently Electronic Arts , a software house that then offered Deluxe Paint , Deluxe Music and others. Electronic Arts also developed the Interchange File Format (IFF) file container, to store project files realized by Deluxe Paint and Deluxe Music. IFF became the de facto standard in AmigaOS. The first to be shown were digitizer software ProPaint (in early beta). Both were used by Andy Warhol to produce

9350-532: The results of operations to be saved and retrieved. It was not until the mid-20th century that the word acquired its modern definition; according to the Oxford English Dictionary , the first known use of the word computer was in a different sense, in a 1613 book called The Yong Mans Gleanings by the English writer Richard Brathwait : "I haue [ sic ] read the truest computer of Times, and

9460-575: The same time that digital calculation replaced analog. The engineer Tommy Flowers , working at the Post Office Research Station in London in the 1930s, began to explore the possible use of electronics for the telephone exchange . Experimental equipment that he built in 1934 went into operation five years later, converting a portion of the telephone exchange network into an electronic data processing system, using thousands of vacuum tubes . In

9570-478: The standard in the home and the office. Many software houses either left the Amiga market or ran into financial troubles. In 1996, Aminet was created. Aminet was the first centralized Internet repository of all Amiga public domain software and documents. It was the first Internet experiment of a centralized software repository created and maintained by one community for the community itself. Amiga's browsers like AWeb , IBrowse and Voyager were enhanced. Voyager

9680-478: The stored-program computer was laid out by Alan Turing in his 1936 paper. In 1945, Turing joined the National Physical Laboratory and began work on developing an electronic stored-program digital computer. His 1945 report "Proposed Electronic Calculator" was the first specification for such a device. John von Neumann at the University of Pennsylvania also circulated his First Draft of a Report on

9790-443: The success of digital electronic computers had spelled the end for most analog computing machines, but analog computers remained in use during the 1950s in some specialized applications such as education ( slide rule ) and aircraft ( control systems ). Claude Shannon 's 1937 master's thesis laid the foundations of digital computing, with his insight of applying Boolean algebra to the analysis and synthesis of switching circuits being

9900-456: The use of Just-in-time compilation , which significantly improved the emulation speed, to the extent that average PCs could now emulate some Amiga software faster than any real Amiga could run it. UAE can use as much of the host's power in native mode as possible, or balance it with other requirements of the host OS, or to accurately reflect the original speed, depending on a user's choice. UAE also provides an RTG -compatible " video card " for

10010-412: The versatility and accuracy of modern digital computers. The first modern analog computer was a tide-predicting machine , invented by Sir William Thomson (later to become Lord Kelvin) in 1872. The differential analyser , a mechanical analog computer designed to solve differential equations by integration using wheel-and-disc mechanisms, was conceptualized in 1876 by James Thomson , the elder brother of

10120-406: Was a 16-transistor chip built by Fred Heiman and Steven Hofstein at RCA in 1962. General Microelectronics later introduced the first commercial MOS IC in 1964, developed by Robert Norman. Following the development of the self-aligned gate (silicon-gate) MOS transistor by Robert Kerwin, Donald Klein and John Sarace at Bell Labs in 1967, the first silicon-gate MOS IC with self-aligned gates

10230-459: Was almost entirely unusable in its first releases, but slowly and step by step, it fleshed out its support of the Amiga chipset and by the end of 1997 was able to emulate an Amiga 500 at a quality and speed that were sufficient for productivity use and for many games. Since then, UAE has been usable, thanks partly to the effort taken to develop it and partly to the big improvements in technology that brought computers many times faster than those UAE

10340-614: Was an early example. Later portables such as the Osborne 1 and Compaq Portable were considerably lighter but still needed to be plugged in. The first laptops, such as the Grid Compass , removed this requirement by incorporating batteries – and with the continued miniaturization of computing resources and advancements in portable battery life, portable computers grew in popularity in the 2000s. The same developments allowed manufacturers to integrate computing resources into cellular mobile phones by

10450-530: Was built with 2000 relays , implementing a 22 bit word length that operated at a clock frequency of about 5–10 Hz . Program code was supplied on punched film while data could be stored in 64 words of memory or supplied from the keyboard. It was quite similar to modern machines in some respects, pioneering numerous advances such as floating-point numbers . Rather than the harder-to-implement decimal system (used in Charles Babbage 's earlier design), using

10560-678: Was changed to a fake 3D aspect using gray shades. For the first time, Commodore introduced a style guide for developers on AmigaOS; because of this, the majority of Amiga software developed for AmigaDOS 2.0 had a standardized GUI that improved usability. Programs such as Imagine 3D , Lightwave , ImageFX , and Scala continued using non-standard GUIs. AmigaVision was released and bundled free with any model of Amiga 3000 . Directory Master, Directory Opus, TurboCalc, Photogenics, ImageFX, PC Task, Photogenics, Caligari, Final Calc, and Cinema 4D all belong to this period. After 1994, Commodore's demise left Amiga to an uncertain future. Windows-based PCs became

10670-501: Was delivered to the University of Manchester in February 1951. At least seven of these later machines were delivered between 1953 and 1957, one of them to Shell labs in Amsterdam . In October 1947 the directors of British catering company J. Lyons & Company decided to take an active role in promoting the commercial development of computers. Lyons's LEO I computer, modelled closely on

10780-443: Was developed by Federico Faggin at Fairchild Semiconductor in 1968. The MOSFET has since become the most critical device component in modern ICs. The development of the MOS integrated circuit led to the invention of the microprocessor , and heralded an explosion in the commercial and personal use of computers. While the subject of exactly which device was the first microprocessor is contentious, partly due to lack of agreement on

10890-825: Was developed in the late 16th century and found application in gunnery, surveying and navigation. The planimeter was a manual instrument to calculate the area of a closed figure by tracing over it with a mechanical linkage. The slide rule was invented around 1620–1630, by the English clergyman William Oughtred , shortly after the publication of the concept of the logarithm . It is a hand-operated analog computer for doing multiplication and division. As slide rule development progressed, added scales provided reciprocals, squares and square roots, cubes and cube roots, as well as transcendental functions such as logarithms and exponentials, circular and hyperbolic trigonometry and other functions . Slide rules with special scales are still used for quick performance of routine calculations, such as

11000-573: Was dubbed the first Amiga " Killer application ". In 1986 (the year of the launch of Amiga 2000 ) Amiga software products contributed to the Amiga's success as a game and multimedia machine. AmigaBasic from Microsoft , VizaWrite , TextCraft (word processors), Pagesetter (Desktop Publishing), Analyze! (Spreadsheet), Superbase Personal (Database), MovieCraft (animation), Deluxe paint II, Deluxe Music, Instant Music (a composition music program for non musicians) from Electronic Arts, and GraphiCraft again from Commodore were released. GraphiCraft

11110-416: Was initially running on. Many Amiga games and applications can run smoothly on a Pentium II -era system. The realization that a useful Amiga emulator could be written contributed to an increase in enthusiasm about emulation, which started or sped-up efforts to write emulators for other and often less popular computer and electronic game architectures. A major improvement was made in 2000 by Bernd Meyer with

11220-449: Was invented by Abi Bakr of Isfahan , Persia in 1235. Abū Rayhān al-Bīrūnī invented the first mechanical geared lunisolar calendar astrolabe, an early fixed- wired knowledge processing machine with a gear train and gear-wheels, c.  1000 AD . The sector , a calculating instrument used for solving problems in proportion, trigonometry , multiplication and division, and for various functions, such as squares and cube roots,

11330-477: Was made of germanium . Noyce's monolithic IC was fabricated using the planar process , developed by his colleague Jean Hoerni in early 1959. In turn, the planar process was based on Carl Frosch and Lincoln Derick work on semiconductor surface passivation by silicon dioxide. Modern monolithic ICs are predominantly MOS ( metal–oxide–semiconductor ) integrated circuits, built from MOSFETs (MOS transistors). The earliest experimental MOS IC to be fabricated

11440-630: Was most likely a form of tally stick . Later record keeping aids throughout the Fertile Crescent included calculi (clay spheres, cones, etc.) which represented counts of items, likely livestock or grains, sealed in hollow unbaked clay containers. The use of counting rods is one example. The abacus was initially used for arithmetic tasks. The Roman abacus was developed from devices used in Babylonia as early as 2400 BCE. Since then, many other forms of reckoning boards or tables have been invented. In

11550-434: Was not Turing-complete. Nine Mk II Colossi were built (The Mk I was converted to a Mk II making ten machines in total). Colossus Mark I contained 1,500 thermionic valves (tubes), but Mark II with 2,400 valves, was both five times faster and simpler to operate than Mark I, greatly speeding the decoding process. The ENIAC (Electronic Numerical Integrator and Computer) was the first electronic programmable computer built in

11660-562: Was one of the first game-oriented computers to feature a built-in floppy disk drive, it simplified software piracy . Many of the arguments pertaining to software copying, intellectual property rights in software, the open-source movement by the early 1990s. It was not unusual for demo groups to be openly involved in software piracy. Anti-piracy measures included the practice of distributing software on disks that contained secret "keys" on high-numbered tracks that were officially unused. The Amiga disk drive officially supported tracks 0–79 from

11770-498: Was sold by HarmonySoft to Aladdin Systems. Some software manufacturers asked users to type a word from a particular page number and line number of the manual, meaning that successfully copying software included photocopying a large quantity of text. Sometimes the text was designed so that photocopiers would produce illegible copies, meaning that pirates had to manually add the text. Pirates responded with " cracking " software that altered

11880-434: Was the first Amiga program to support Disk At Once (DAO). Frying Pan was the first Amiga program capable to create DVDs. Frying Pan and BurnIt! are capable to handle DVD. BlueHD from German programmer Carsten Siegner is a MorphOS program capable of authoring and burning HD-DVDs in these formats: (A complete list of ISO managements and converters is available on Aminet.) AmiDock creates application launching docks on

11990-519: Was the first browser to adopt tabbed browsing . Mailers like YAM are still used. In productivity software, programs like Candy Factory for image processing were still being developed, for VFX and animation programs like Wildfire by Andreas Maschke (ported by the author to Java later). other prominent graphic software include fxPAINT by IOSpirit, fxSCAN for OCR and scanning by IOSpirit , and SketchBlock painting program by Andy Broad for AmigaOS 4.x. Last but not least Tornado3D raytracing program by

12100-577: Was used by computer artist Jim Sachs to produce Amiga software such as Defender of the Crown and Centurion: Defender of Rome from Cinemaware and the Amiga porting of Saucer Attack . Graphicraft was a predecessor of Aegis Images and AEGIS Animator , one of the first programs worldwide capable of creating animation videos and cartoons complete with audio stereo, featuring a cel animation working paradigm interface and outputting files based on delta-frame difference compression method which then were
