A smartbook was a class of mobile device that combined certain features of both a smartphone and netbook computer, produced between 2009 and 2010. Smartbooks were advertised with features such as always on , all-day battery life, 3G , or Wi-Fi connectivity and GPS (all typically found in smartphones) in a laptop or tablet-style body with a screen size of 5 to 10 inches and a physical or soft touchscreen keyboard.
103-542: A German company sold laptops under the brand Smartbook and held a trademark for the word in many countries (not including some big markets like United States , China , Japan , or India ). It acted to preempt others from using the term smartbook to describe their products. Smartbooks tended to be designed more for entertainment purposes than for productivity and typically targeted to work with online applications. They were projected to be sold subsidized through mobile network operators , like mobile phones , along with
206-447: A hard disk drive (HDD) for storage; since then, solid-state drives (SSD) have gradually come to supplant hard drives in all but some inexpensive consumer models. Solid-state drives are faster and more power-efficient, as well as eliminating the hazard of drive and data corruption caused by a laptop's physical impacts, as they use no mechanical parts such as a rotational platter. In many cases, they are more compact as well. Initially, in
309-417: A separate graphics processor were limited in their utility for gaming and professional applications involving 3D graphics, but the capabilities of CPU-integrated graphics have converged with the low-end of dedicated graphics processors since the mid-2010s. For laptops possessing limited onboard graphics capability but sufficient I/O throughput, an external GPU (eGPU) can provide additional graphics power at
412-408: A 2 GB or larger installation medium. The last release of Ubuntu available on a minimal CD was 18.04. 32-bit x86 processors were supported up to Ubuntu 18.04. It was decided to support " legacy software ", i.e. select 32-bit i386 packages , for Ubuntu 19.10 (since out of support) and 20.04 LTS. On 9 August 2024, Ubuntu announced a change in policy to always use the latest upstream code of
515-399: A 5.5" touchscreen, runs Ubuntu on an ARM Cortex-A8 based Freescale i.MX515 and was packaged in a small clamshell design. Sharp reported the device weighs less than 500 grams and will run 10 hours on one battery charge. The device is said to run 720p video, and have both 2D and 3D graphics acceleration. It comes with Adobe Flash Lite 3.1 installed. Pegatron, an Asus company, showed
618-414: A broad range of devices, which combined features of several previously separate device types. The hybrids , convertibles , and 2-in-1s emerged as crossover devices, which share traits of both tablets and laptops. All such devices have a touchscreen display designed to allow users to work in a tablet mode, using either multi-touch gestures or a stylus / digital pen . Convertibles are devices with
721-399: A developer. In combination with other freezes, this helps packagers ensure that frozen features interoperate well together. Ubuntu aims to be secure by default. User programs run with low privileges and cannot corrupt the operating system or other users' files. For increased security, the sudo tool is used to assign temporary privileges for performing administrative tasks, which allows
824-461: A different set of default packages compared to the standard Ubuntu Desktop. Since they share the same package repositories, all of the same software is available for each of them. Ubuntu Core is the sole exception as it only has access to packages in the Snap Store. The server edition (like the desktop version) supports hardware virtualization and can be run in a virtual machine , either inside
927-458: A few high-end models intended for gaming do as well. As of 2021, 8 GB RAM is most common, with lower-end models occasionally having 4 GB. Higher-end laptops may come with 16 GB of RAM or more. The earliest laptops most often used floppy disk for storage, although a few used either RAM disk or tape, by the late 1980s hard disk drives had become the standard form of storage. Between 1990 and 2009, almost all laptops typically had
1030-405: A full-featured desktop OS like Windows 10 , and have a number of typical laptop I/O ports, such as USB 3 and Mini DisplayPort . 2-in-1s are designed to be used not only as a media consumption device but also as valid desktop or laptop replacements, due to their ability to run desktop applications, such as Adobe Photoshop . It is possible to connect multiple peripheral devices, such as
1133-784: A host operating system or in a hypervisor , such as VMware ESXi , Oracle , Citrix XenServer , Microsoft Hyper-V , QEMU , a Kernel-based Virtual Machine , or any other IBM PC compatible emulator or virtualiser. AppArmor security module for the Linux kernel is used by default on key software packages, and the firewall is extended to common services used by the operating system. It has versions of key server software pre-installed, including Tomcat, PostgreSQL (v12.2), Docker, Puppet, Python (v3.9), PHP (v8.0), NGINX (v1.17), and MySQL (v8.0). Ubuntu had some official distributions that have been discontinued, such as Gobuntu ; including some previously supported by Canonical, like Ubuntu Touch , that

The Dell M17x and Samsung 700G7A, both released in 2011, were among the first laptops to feature a 120 Hz refresh rate, and more such laptops have appeared in the years since. A laptop's CPU has advanced power-saving features and produces less heat than one intended purely for desktop use. Mainstream laptop CPUs made after 2018 have at least two processor cores, often four cores, and sometimes more, with 6 and 8 cores becoming more common. For
1339-506: A list which is a reordering of former list, ordered by power-efficiency. On the TOP500 list, that supercomputer was ranked 170nd (and many Ubuntu-based rank higher than that). The public sector has also adopted Ubuntu. As of January 2009 , the Ministry of Education and Science of North Macedonia deployed more than 180,000 Ubuntu-based classroom desktops, and has encouraged every student in
1442-510: A mouse, keyboard, and several external displays to a modern 2-in-1. Microsoft Surface Pro-series devices and Surface Book are examples of modern 2-in-1 detachable, whereas Lenovo Yoga -series computers are a variant of 2-in-1 convertibles. While the older Surface RT and Surface 2 have the same chassis design as the Surface Pro, their use of ARM processors and Windows RT do not classify them as 2-in-1s, but as hybrid tablets. Similarly,
1545-742: A number of hybrid laptops run a mobile operating system , such as Android . These include Asus's Transformer Pad devices, examples of hybrids with a detachable keyboard design, which do not fall in the category of 2-in-1s. A rugged laptop is designed to reliably operate in harsh usage conditions such as strong vibrations, extreme temperatures, and wet or dusty environments. Rugged laptops are bulkier, heavier, and much more expensive than regular laptops, and thus are seldom seen in regular consumer use. The basic components of laptops function identically to their desktop counterparts. Traditionally they were miniaturized and adapted to mobile use, The design restrictions on power, size, and cooling of laptops limit
1648-444: A partner repository that let vendors of proprietary software deliver their products to Ubuntu users at no cost through the same familiar tools for installing and upgrading software. The software in the partner repository was officially supported with security and other important updates by its respective vendors. Canonical supported the packaging of the software for Ubuntu and provided guidance to vendors. However, in anticipation for
1751-485: A small niche market , mostly for specialized field applications, such as in the military, for accountants, or travelling sales representatives. As portable computers evolved into modern laptops, they became widely used for a variety of purposes. The history of the laptop follows closely behind the development of the personal computer itself. A "personal, portable information manipulator" was imagined by Alan Kay at Xerox PARC in 1968, and described in his 1972 paper as
1854-423: A smartbook, but due to the popularity of tablets, MacBook Air and Ultrabooks , plans were scrapped. Laptop A laptop computer or notebook computer , also known as a laptop or notebook , is a small, portable personal computer (PC). Laptops typically have a clamshell form factor with a flat-panel screen on the inside of the upper lid and an alphanumeric keyboard and pointing device on
1957-493: A standard for memory cards in PCs. The specification for PCMCIA type I cards, later renamed PC Cards, was first released in 1990. Displays reached 640x480 ( VGA ) resolution by 1988 ( Compaq SLT/286 ), and color screens started becoming a common upgrade in 1991, with increases in resolution and screen size occurring frequently until the introduction of 17" screen laptops in 2003. Hard drives started to be used in portables, encouraged by
2060-587: A type of portable computer that was smaller and lighter than mainstream laptops of the time, but has since come to mean the same thing and no longer refers to any specific size. Laptops are used in a variety of settings, such as at work (especially on business trips ), in education , for playing games , web browsing , for personal multimedia , and for general home computer use. They can run on both AC power and rechargable battery packs and can be folded shut for convenient storage and transportation, making them suitable for mobile use . Laptops combine many of
2163-485: A wide range of CPUs designed for laptops available from both Intel , AMD , and other manufacturers. On non- x86 architectures, Motorola and IBM produced the chips for the former PowerPC -based Apple laptops ( iBook and PowerBook ). Between around 2000 to 2014, most full-size laptops had socketed, replaceable CPUs; on thinner models, the CPU was soldered on the motherboard and was not replaceable or upgradable without replacing

It consisted of an ARM Cortex-A8 based Freescale i.MX515 supports 2D/3D graphics as well as 720p HD video, 512 MB DDR2 RAM , 1024x600 8.9" LCD screen, Bluetooth 2.0, 802.11g and run off a SD card . It also featured one USB and one micro USB port, a VGA port as well as a card reader. The smartbook ran Ubuntu Netbook 9.04 and contained a version of Adobe Flash Player which
2472-462: Is 24.04 ("Noble Numbat"). As with other Linux distributions, all of the editions can run on a computer alone, or in a virtual machine . An upgrade to Ubuntu is released every six months, with long-term support (LTS) releases every two years. Canonical provides security updates and support for each Ubuntu release, starting from the release date until the release reaches its designated end-of-life (EOL) date. Canonical generates revenue through
2575-398: Is a concept for a laptop that can be easily disassembled. The terms laptop and notebook both trace their origins to the early 1980s, coined to describe portable computers in a size class smaller than the contemporary mainstream units (so-called "luggables" ) but larger than pocket computers . The etymologist William Safire traced the origin of laptop to some time before 1984;
2678-468: Is able to remain in stand-by mode for up to 7 days. The device was officially available at the Toshiba United Kingdom site. Originally delivered with Android v2.1 (upgradable to v2.2 since 2011 ) it can also be modified to run a customized Linux distribution. In Japan, was sold as "Dynabook AZ". The Genesi company announced an MX Smartbook as part of their Efika line in August 2010. It
2781-434: Is also officially supported. Live images are the typical way for users to assess and subsequently install Ubuntu. These can be downloaded as a disk image ( .iso ) and subsequently burnt to a DVD or USB flash drive and then booted. Other methods include running the live version via Ventoy , UNetbootin , Universal USB Installer , or Startup Disk Creator (a pre-installed tool on Ubuntu, available on machines already running
2884-504: Is also prevalent on VPS platforms such as DigitalOcean . Ubuntu has support for OpenStack, with Eucalyptus to OpenStack migration tools added by Canonical. Ubuntu 11.10 added focus on OpenStack as the Ubuntu's preferred IaaS offering though Eucalyptus is also supported. Another major focus is Canonical Juju for provisioning, deploying, hosting, managing, and orchestrating enterprise data center infrastructure services, by, with, and for
2987-416: Is available to configure it. Ubuntu compiles its packages using GCC features such as PIE and buffer overflow protection to harden its software. These extra features greatly increase security at the performance expense of 0.01% in 64-bit . Ubuntu also supports full disk encryption as well as encryption of the home and private directories. The system requirements vary among Ubuntu products. For

3296-584: Is more limited than that of Main, because the developers may not have access to the source code . It is intended that Main and Restricted should contain all software needed for a complete desktop environment. In addition to the above, in which the software does not receive new features after an initial release, Ubuntu Backports is an officially recognised repository for backporting newer software from later versions of Ubuntu. The -updates repository provides stable release updates (SRU) of Ubuntu and are generally installed through update-manager. Each release

Non-free software is usually unsupported (Multiverse), but some exceptions (Restricted) are made for important non-free software. Supported non-free software includes device drivers that can be used to run Ubuntu on some current hardware, such as binary-only graphics card drivers . The level of support in the Restricted category
3708-430: Is not unknown as of 2022, but since around 2010, the practice has been restricted to small-volume gaming models. Laptop CPUs are rarely able to be overclocked ; most use locked processors. Even on gaming models where unlocked processors are available, the cooling system in most laptops is often very close to its limits and there is rarely headroom for an overclocking–related operating temperature increase. On most laptops,
3811-426: Is now maintained by volunteers (UBports Community). Alongside the official flavours are those that are unofficial. These are still in the process of becoming recognised as official flavours by Canonical. Ubuntu offers Ubuntu Cloud Images which are pre-installed disk images that have been customised by Ubuntu engineering to run on cloud-platforms such as Amazon EC2 , OpenStack , Microsoft Azure and LXC . Ubuntu
3914-463: Is officially released in multiple editions: Desktop , Server , and Core for Internet of things devices and robots . The operating system is developed by the British company Canonical and a community of other developers, under a meritocratic governance model. As of October 2024 , the latest interim release is 24.10 ("Oracular Oriole"), with most-recent long-term support release
4017-407: Is possible to skip an LTS upgrade, going straight from 16.04 LTS to 18.04.5 LTS, by waiting for a point release that supports such updating. LTS releases have optional extended security maintenance (ESM) support available, including e.g. 18.04 "Bionic" that is otherwise out of public support, adding support for that version up to 2028, giving a total of 10 years. Ubuntu 10.10 (Maverick Meerkat) ,

As of version 24.10, a default installation of Ubuntu contains a minimal selection of software, namely a web browser ( Firefox ) and basic GNOME utilities (including the desktop). Many additional software packages are accessible from the built-in Ubuntu Software (previously Ubuntu Software Center ) as well as any other APT-based package management tools. Many additional software packages that are no longer installed by default, such as Evolution , GIMP , Pidgin , and Synaptic , are still accessible in
4429-501: The RAR file format . Additionally, third-party application suites are available for download via Ubuntu Software and the Snap store , including many games such as Braid , Minecraft and Oil Rush , software for DVD playback and media codecs. Each Ubuntu release has a version number that consists of the year and month number of the release. For example, the first release was Ubuntu 4.10 as it
4532-576: The Socket G2 , but many laptops use processors that are soldered to the motherboard. Many laptops come with RAM and storage that is soldered to the motherboard and cannot be easily replaced. This restriction is one of the major differences between laptops and desktop computers, because the large " tower " cases used in desktop computers are designed so that new motherboards , hard disks , sound cards , RAM , and other components can be added. Memory and storage can often be upgraded with some disassembly, but with

The US$ 8,150 (equivalent to $ 25,730 in 2023) GRiD Compass 1101 , released in 1982, was used at NASA and by the military , among others. The Sharp PC-5000 , the Ampere WS-1 , and Gavilan SC were released between 1983 and 1985. The Toshiba T1100 won acceptance by PC experts and
4738-626: The iPad already occupied the niche of the smartbook, so the name was dropped. In February 2011 Qualcomm won its legal battle when the German patent office ruled the words "smart" and "book" could be used. However, several trademarks have been registered. In March 2009 the Always Innovating company announced the Touch Book . It was based on the Texas Instruments OMAP 3530 which implemented

The IBM 5100 , the first commercially available portable computer , appeared in September 1975, and was based on the SCAMP prototype. As 8-bit CPU machines became widely accepted, the number of portables increased rapidly. The first "laptop-sized notebook computer"
5150-1055: The 'Ubuntu stack' (cloud computing infrastructure). The first LTS releases were supported for three years on the desktop and five years on the server; since Ubuntu 12.04 LTS, desktop support for LTS releases was increased to five years as well. LTS releases get regular point releases with support for new hardware and integration of all the updates published in that series to date. Ubuntu packages are based on Debian 's unstable branch, which are synchronized every six months. Both distributions use Debian's deb package format and package management tools (e.g. APT and Ubuntu Software ). Debian and Ubuntu packages are not necessarily binary compatible with each other, however, so packages may need to be rebuilt from source to be used in Ubuntu. Many Ubuntu developers are also maintainers of key packages within Debian. Ubuntu cooperates with Debian by pushing changes back to Debian, although there has been criticism that this does not happen often enough. Ian Murdock ,

Excepting distinct legal trademark around terms (notably Ultrabook ), hard distinctions between these classes were rare, and their usage has varied over time and between sources. Since the late 2010s, more specific terms have become less commonly used, with sizes distinguished largely by

The development of memory cards was driven in the 1980s by the need for a floppy-disk-drive alternative, having lower power consumption, less weight, and reduced volume in laptops. The Personal Computer Memory Card International Association (PCMCIA) was an industry association created in 1989 to promote
5459-509: The 2011 Samsung 700G7A have passed the 10 GB RAM barrier, featuring 16 GB of RAM. When upgradeable, memory slots are sometimes accessible from the bottom of the laptop for ease of upgrading; in other cases, accessing them requires significant disassembly. Most laptops have two memory slots, although some will have only one, either for cost savings or because some amount of memory is soldered. Some high-end models have four slots; these are usually mobile engineering workstations, although
5562-635: The ARM architecture delayed releases until the first quarter of 2010. Smartbooks would have been powered by processors which were more energy-efficient than traditional ones typically found in desktop and laptop computers. The first smartbooks were expected to use variants of the Linux operating system , such as Google's Android or ChromeOS . The ARM processor would have allowed them to achieve longer battery life than many larger devices using x86 processors. In February 2010, ABI Research projected that 163 million smartbooks would ship in 2015. In many countries
5665-546: The GPU is integrated into the CPU to conserve power and space. This was introduced by Intel with the Core i-series of mobile processors in 2010, followed by similar AMD APU processors in January 2011. Before that, lower-end machines tended to use graphics processors integrated into the system chipset , while higher-end machines had a separate graphics processor. In the past, laptops lacking

In addition, Ubuntu redistributes some hardware drivers that are available only in binary format, but such packages are clearly marked in the restricted component. Current long-term support (LTS) releases are supported for five years, and are released every two years. Since the release of Ubuntu 6.06, every fourth release receives long-term support. Long-term support includes updates for new hardware, security patches and updates to

Higher-end laptops intended for gaming or professional 3D work still come with dedicated (and in some cases even dual) graphics processors on the motherboard or as an internal expansion card . Since 2011, these almost always involve switchable graphics so that when there is no demand for the higher performance dedicated graphics processor, the more power-efficient integrated graphics processor will be used. Nvidia Optimus and AMD Hybrid Graphics are examples of this sort of system of switchable graphics. Traditionally,

7210-600: The end of March 2010 the smartbook made an appearance at FCC again, this time listing its 3G capabilities. According to FCC, the device will support GSM 850 and 1900, as well as WCDMA II and V bands. These WCDMA bands may indicate the usage in AT&;T network in the United States. Details of the product is now available on the HP website. In June 2010, a smartbook device from Toshiba was announced. It features Nvidia Tegra processor and
7313-490: The founder of Debian, had expressed concern about Ubuntu packages potentially diverging too far from Debian to remain compatible. Before release, packages are imported from Debian unstable continuously and merged with Ubuntu-specific modifications. At some point during the release process, the Debian Import Freeze is implemented. This prevents the automatic import of packages from Debian without an explicit request from
7416-763: The higher resolutions on smaller screens, the resolution may only serve to display sharper graphics and text rather than increasing the usable area. Since the introduction of the MacBook Pro with Retina display in 2012, there has been an increase in the availability of "HiDPI" (or high Pixel density ) displays; as of 2022, this is generally considered to be anything higher than 1920 pixels wide. This has increasingly converged around 4K (3840-pixel-wide) resolutions. External displays can be connected to most laptops, with most models supporting at least one. The use of technology such as USB4 (section Alternate Mode partner specifications ). DisplayPort Alt Mode has been utilized to charge
7519-483: The inside of the lower lid. Most of the computer's internal hardware is fitted inside the lower lid enclosure under the keyboard, although many modern laptops have a built-in webcam at the top of the screen, and some even feature a touchscreen display. In most cases, unlike tablet computers which run on mobile operating systems , laptops tend to run on desktop operating systems, which were originally developed for desktop computers . The word laptop , modeled after
7622-644: The intended use. Examples of specialized models of laptops include 2-in-1 laptops , with keyboards that either be detached or pivoted out of view from the display (often marketed having a "laptop mode"); rugged laptops , for use in construction or military applications ; and low-production-cost laptops such as those from the One Laptop per Child (OLPC) organization, which incorporate features like solar charging and semi-flexible components not found on most laptop computers. Portable computers , which later developed into modern laptops, were originally considered to be
7725-464: The introduction of 3.5" drives in the late 1980s, and became common in laptops starting with the introduction of 2.5" and smaller drives around 1990; capacities have typically lagged behind those of physically larger desktop drives. Resolutions of laptop webcams are 720p (HD), or 480p in lower-end laptops. The earliest-known laptops with 1080p (Full HD) webcams, like the Samsung 700G7C, were released in
7828-455: The late 2000s, SSDs were substantially more expensive than HDDs, but as of 2021 prices on smaller capacity (under 1 terabyte ) drives have converged; larger capacity drives remain more expensive than comparable-sized HDDs. Ubuntu (operating system) Ubuntu ( / ʊ ˈ b ʊ n t uː / uu- BUUN -too ) is a Linux distribution derived from Debian and composed mostly of free and open-source software . Ubuntu
7931-492: The live environment. The Ubuntu Desktop Installer replaced the former Ubiquity installer since Ubuntu 23.04. Disk images of all current and past versions are available for download at the Ubuntu web site. Additionally, USB flash drive installations can be used to boot Ubuntu and Kubuntu in a way that allows permanent saving of user settings and portability of the USB-installed system between physical machines (however,
8034-478: The low price and mainstream performance, there is no longer a significant performance difference between laptop and desktop CPUs, but at the high end, the fastest desktop CPUs still substantially outperform the fastest laptop processors, at the expense of massively higher power consumption and heat generation; the fastest laptop processors top out at 56 watts of heat, while the fastest desktop processors top out at 150 watts (and often need water cooling). There has been
8137-560: The mass market as a way to have PC portability. From 1983 onward, several new input techniques were developed and included in laptops, including the touch pad ( Gavilan SC , 1983), the pointing stick (IBM ThinkPad 700 , 1992), and handwriting recognition (Linus Write-Top, 1987). Some CPUs, such as the 1990 Intel i386SL , were designed to use minimum power to increase the battery life of portable computers and were supported by dynamic power management features such as Intel SpeedStep and AMD PowerNow! in some designs. Some laptops in
8240-406: The maximum performance of laptop parts compared to that of desktop components, although that difference has increasingly narrowed. In general, laptop components are not intended to be replaceable or upgradable by the end-user, except for components that can be detached; in the past, batteries and optical drives were commonly exchangeable. Some laptops feature socketed processors with sockets such as
8343-479: The most compact laptops, there may be no upgradeable components at all. The following sections summarize the differences and distinguishing features of laptop components in comparison to desktop personal computer parts. The typical laptop has a screen that, when unfolded, is upright to the user. Laptop screens most commonly employ liquid-crystal display (LCD) technology, although use of OLED panels has risen substantially since 2020. The display interfaces with
8446-516: The most page requests to Wikimedia sites, including Misplaced Pages, among recognizable Linux distributions. As of June 2024 , Ubuntu 22.04 is used in Microsoft NDv5, a Microsofts Azure cloud computer , its fastest one (of 7 Azure supercomputers, all running on Ubuntu), currently 3rd fastest supercomputer on the TOP500 list (only beaten by the only two exaflop computers; is itself half an exaflop , only
8549-921: The motherboard using the embedded DisplayPort protocol via the Low-voltage differential signaling (LVDS) 30 or 40 pin connector. The panels are mainly manufactured by AU Optronics , BOE Technology , LG Display or Samsung Display . Externally, it can be a glossy or a matte (anti-glare) screen. In the past, there was a broader range of marketing terms (both formal and informal) to distinguish between different sizes of laptops. These included Netbooks , subnotebooks , Ultra-mobile PC , and Desktop replacement computers ; these are sometimes still used informally, although they are essentially dead in terms of manufacturer marketing. As of 2021, mainstream consumer laptops tend to come with 11", 13" or 15"-16" screens; 14" models are more popular among business machines. Larger and smaller models are available, but less common – there
8652-428: The motherboard. Since 2015, Intel has not offered new laptop CPU models with pins to be interchangeable, preferring ball grid array chip packages which have to be soldered; and as of 2021, only a few rare models using desktop parts. In the past, some laptops have used a desktop processor instead of the laptop version and have had high-performance gains at the cost of greater weight, heat, and limited battery life; this
8755-536: The release of Ubuntu 22.04 LTS Canonical closed the partner repository, as the only package still hosted in it was Adobe Flash , which would not be released with 22.04. Ubuntu developer Steve Langasek said in a development mailing list that he felt the "Snap Store has matured to the point that I believe it supersedes the partner archive". A Personal Package Archive (PPA) is a software repository for uploading source packages to be built and published as an Advanced Packaging Tool (APT) repository by Launchpad . While
8858-474: The release of the NEC UltraLite in 1988. Notebooks and laptops continued to occupy distinct market segments into the mid-1990s, but ergonomic considerations and customer preference for larger screens soon led to notebooks converging with laptops in the late 1990s. Today, the terms laptop and notebook are synonymous, with laptop being the more common term in most English-speaking territories. Since
8961-409: The release. In addition to the -updates repository, the unstable -proposed repository contains uploads that must be confirmed before being copied into -updates. All updates must go through this process to ensure that the patch does truly fix the bug and there is no risk of regression . Updates in -proposed are confirmed by either Canonical or members of the community. Canonical previously hosted
9064-485: The repositories and installable by the main tool or by any other APT-based package management tool. Cross-distribution snap packages and Flatpaks are also available, that both allow installing software, such as some of Microsoft's software, in most of the major Linux operating systems (such as any currently supported Ubuntu version and in Fedora ). The default file manager is GNOME Files , formerly called Nautilus. All of
9167-457: The sale of premium services related to the Ubuntu software and donations from those who download Ubuntu directly. Ubuntu is named after the Nguni philosophy of ubuntu , "humanity to others" with a connotation of "I am what I am because of who we all are". Since the release of the first version in 2004, Ubuntu has become one of the most popular Linux distributions for general purposes and
9270-432: The size of mainstream laptops has gone down and their capabilities have gone up; except for niche models, laptop sizes tend to be distinguished by the size of the screen, and for more powerful models, by any specialized purpose the machine is intended for, such as a " gaming laptop " or a " mobile workstation " for professional use. The latest trend of technological convergence in the portable computer industry spawned
9373-511: The size of the screen. There were in the past a number of marketing categories for smaller and larger laptop computers; these included "notebook" and " subnotebook " models, low cost " netbooks ", and " ultra-mobile PCs " where the size class overlapped with devices like smartphone and handheld tablets , and " Desktop replacement " laptops for machines notably larger and heavier than typical to operate more powerful processors or graphics hardware . All of these terms have fallen out of favor as
9476-418: The system RAM on laptops (as well as on desktop computers) was physically separate from the graphics memory used by the GPU. Apple's M series SoCs feature a unified pool of memory for both the system and the GPU; this approach can produce substantial efficiency gains for some applications but comes at the cost of eGPU support. Since around the year 2000, most laptops have used SO-DIMM slots in which RAM
9579-491: The term desktop (as in desktop computer ), refers to the fact that the computer can be practically placed on the user's lap ; while the word notebook refers to most laptops sharing a form factor with paper notebooks . As of 2024 , in American English , the terms laptop and notebook are used interchangeably; in other dialects of English , one or the other may be preferred. The term notebook originally referred to
9682-488: The term is used exclusively within Ubuntu, Launchpad's host, Canonical , envisions adoption beyond the Ubuntu community. Some third-party software that does not limit distribution is included in Ubuntu's multiverse component. The package ubuntu-restricted-extras additionally contains software that may be legally restricted, including support for DVD playback, Microsoft TrueType core fonts , many common audio/video codecs , and unrar, an unarchiver for files compressed in
9785-505: The top 3 are that powerful). Other supercomputers running Ubuntu rank also high on the list e.g. NVIDIA's Selene supercomputer still ranks highly, and was fifth-fastest one in the world in November 2022 after an upgrade from seventh place, where it entered the list in June. Another Nvidia-based supercomputer using Ubuntu previously topped the Green500 list (it and the next one was also Ubuntu-based),
9888-414: The word Smartbook was a trademark registered by Smartbook AG. In August 2009 a German court ruled Qualcomm must block access from Germany to all its webpages containing the word Smartbook unless Smartbook AG is mentioned. Smartbook AG defended its trademark. A February 2010 ruling prevented Lenovo from using the term. By the end of 2010, Qualcomm CEO Paul Jacobs admitted that tablet computers such as
9991-516: Was in October 2004. Ubuntu is currently funded by Canonical Ltd . On 8 July 2005, Mark Shuttleworth and Canonical announced the creation of the Ubuntu Foundation and provided initial funding of US$ 10 million. The purpose of the foundation is to ensure the support and development for all future versions of Ubuntu. Mark Shuttleworth describes the foundation's goal to ensure the continuity of
10094-437: Was originally priced at US$ 349, and some reviewers questioned if it was small enough to fit this definition. It is ostensibly a derivative of the above-mentioned Pegatron design. In September 2009, Foxconn announced it is working on smartbook development. In November 2009, a Quanta Computer pre-production Snapdragon powered sample smartbook device that ran Android was unveiled. Companies like Acer Inc. planned to release
10197-530: Was out of date. The bill of materials for the Pegatron smartbook prototype was $ 120. In November 2009 Pegatron said it had received a large number of orders for smartbooks that would launch in early 2010. The devices were rumored to sell for about $ 200 when subsidized. Asus announced plans to release their own smartbook in the first quarter of 2010. Qualcomm was expected to announce a smartbook on November 12, 2009, at an analyst meeting. A Lenovo device concept
10300-576: Was released on 10 October 2010 (10–10–10). This departed from the traditional schedule of releasing at the end of October in order to get "the perfect 10", and makes a playful reference to The Hitchhiker's Guide to the Galaxy books, since, in binary , 101010 equals decimal 42 , the "Answer to the Ultimate Question of Life, the Universe and Everything" within the series. Ubuntu Desktop (formally named as Ubuntu Desktop Edition, and simply called Ubuntu)
10403-440: Was released on 20 October 2004. Ubuntu releases are also given alliterative code names , using an adjective and an animal (e.g., "Bionic Beaver"). With the exception of the first two releases, code names are in alphabetical order, allowing a quick determination of which release is newer, at least until restarting the cycle with the release of Artful Aardvark in October 2017. Commonly, Ubuntu releases are referred to using only
10506-556: Was shown, and announced in January 2010. In May 2010 the Skylight was cancelled. In late January 2010 a U.S. Federal Communications Commission (FCC) listing featured a device from HP that was referred as smartbook , while a prototype of the same device was already shown earlier. In beginning February on Mobile World Congress in Barcelona, HP announced it will bring this device to market. The specifications will most likely be following: In
