91-518: Modular Windows is a special version of Microsoft Windows 3.1 , designed to run on the Tandy Video Information System. Microsoft intended Modular Windows to be an embedded operating system for various devices, especially those designed to be connected to televisions . However, the VIS is the only known product that actually used this Windows version. It has been claimed that Microsoft created

182-442: A TV set or an appropriately sized computer display , and is often used as a digital photo viewer, music and video player, TV receiver, and digital video recorder. HTPCs are also referred to as media center systems or media servers . The goal is to combine many or all components of a home theater setup into one box. HTPCs can also connect to services providing on-demand movies and TV shows. HTPCs can be purchased pre-configured with

273-455: A Winsock package was released for Windows for Workgroups, although it was later replaced by a 32-bit stack add-on package (codenamed Wolverine) that provided TCP/IP support in Windows for Workgroups 3.11. Its connectivity with NetWare networks was increased, while it also introduced support for Open Data-Link Interface cards and Internetwork Packet Exchange drivers. Remote access service

364-401: A kit form and in limited volumes, and were of interest mostly to hobbyists and technicians. Minimal programming was done with toggle switches to enter instructions, and output was provided by front panel lamps. Practical use required adding peripherals such as keyboards, computer displays , disk drives , and printers . Micral N was the earliest commercial, non-kit microcomputer based on

455-507: A multitasking operating system . Eventually, due to the influence of the IBM PC on the personal computer market , personal computers and home computers lost any technical distinction. Business computers acquired color graphics capability and sound, and home computers and game systems users used the same processors and operating systems as office workers. Mass-market computers had graphics capabilities and memory comparable to dedicated workstations of

546-544: A portable computer prototype called SCAMP (Special Computer APL Machine Portable) based on the IBM PALM processor with a Philips compact cassette drive, small CRT , and full function keyboard. SCAMP emulated an IBM 1130 minicomputer in order to run APL/1130. In 1973, APL was generally available only on mainframe computers, and most desktop sized microcomputers such as the Wang 2200 or HP 9800 offered only BASIC . Because SCAMP

637-469: A touchscreen display, which can be controlled using either a stylus pen or finger. Some tablets may use a hybrid or convertible design, offering a keyboard that can either be removed as an attachment, or a screen that can be rotated and folded directly over top the keyboard. Some tablets may use desktop-PC operating system such as Windows or Linux, or may run an operating system designed primarily for tablets. Many tablet computers have USB ports, to which

728-442: A "business disappointment" due to its small amount of sold copies. Regarding the marketplace, Windows 3.1 had received an enthusiastic reception; its retail price sat at $ 149, and over three million copies of Windows 3.1 were sold in the first three months. The year of Windows 3.1's release was successful for Microsoft, which was named the "Most Innovative Company Operating in the U.S." by Fortune magazine, while Windows became

819-831: A 4096-color palette, stereo sound, Motorola 68000 CPU, 256 KB RAM, and 880 KB 3.5-inch disk drive, for US$ 1,295. IBM's first PC was introduced on 12 August 1981 setting what became a mass market standard for PC architecture. In 1982 The Computer was named Machine of the Year by Time magazine. Somewhat larger and more expensive systems were aimed at office and small business use. These often featured 80-column text displays but might not have had graphics or sound capabilities. These microprocessor-based systems were still less costly than time-shared mainframes or minicomputers. Workstations were characterized by high-performance processors and graphics displays, with large-capacity local disk storage, networking capability, and running under

910-410: A computer that could fit on a desk was remarkably small, leading to the desktop nomenclature. More recently, the phrase usually indicates a particular style of computer case . Desktop computers come in a variety of styles ranging from large vertical tower cases to small models which can be tucked behind or rest directly beneath (and support) LCD monitors . While the term desktop often refers to

1001-557: A computer with a vertically aligned computer tower case , these varieties often rest on the ground or underneath desks. Despite this seeming contradiction, the term desktop does typically refer to these vertical tower cases as well as the horizontally aligned models which are designed to literally rest on top of desks and are therefore more appropriate to the desktop term, although both types qualify for this desktop label in most practical situations aside from certain physical arrangement differences. Both styles of these computer cases hold

1092-506: A desk, including a keyboard, a small one-line display, and printer. The Wang 2200 microcomputer of 1973 had a full-size cathode ray tube (CRT) and cassette tape storage. These were generally expensive specialized computers sold for business or scientific uses. 1974 saw the introduction of what is considered by many to be the first true personal computer, the Altair 8800 created by Micro Instrumentation and Telemetry Systems (MITS) . Based on

1183-415: A few years before. Even local area networking, originally a way to allow business computers to share expensive mass storage and peripherals, became a standard feature of personal computers used at home. An increasingly important set of uses for personal computers relied on the ability of the computer to communicate with other computer systems, allowing interchange of information. Experimental public access to

1274-597: A free upgrade to anyone who owned Windows 3.1. An updated Simplified Chinese version of Windows 3.1 was released in November 1993, as Windows 3.2. The update was limited to this language version, as it only fixed issues related to the complex input system for the Simplified Chinese language. A font editor is present in Windows 3.2; it is used to add new Chinese characters to the already-existing fonts. Windows for Workgroups served as an update to Windows 3.1, and it

1365-432: A graphics card installed. For this reason, desktop computers are usually preferred over laptops for gaming purposes. Unlike desktop computers, only minor internal upgrades (such as memory and hard disk drive) are feasible owing to the limited space and power available. Laptops have the same input and output ports as desktops, for connecting to external displays, mice, cameras, storage devices and keyboards. Laptops are also

1456-484: A hinged second panel containing a flat display screen. Closing the laptop protects the screen and keyboard during transportation. Laptops generally have a rechargeable battery , enhancing their portability. To save power, weight and space, laptop graphics chips are in many cases integrated into the CPU or chipset and use system RAM, resulting in reduced graphics performance when compared to desktop machines, that more typically have

1547-408: A keyboard or mouse can be connected. Smartphones are often similar to tablet computers , the difference being that smartphones always have cellular integration. They are generally smaller than tablets, and may not have a slate form factor. The ultra-mobile PC (UMPC) is a small tablet computer . It was developed by Microsoft , Intel and Samsung , among others. Current UMPCs typically feature

1638-530: A larger screen or use with video projectors. IBM PC-compatible suitcase format computers became available soon after the introduction of the PC, with the Compaq Portable being a leading example of the type. Later models included a hard drive to give roughly equivalent performance to contemporary desktop computers. The development of thin plasma display and LCD screens permitted a somewhat smaller form factor, called

1729-562: A lawsuit against Microsoft over the AARD code, which was later settled with Microsoft paying $ 280 million. Windows 3.1 found a niche market as an embedded operating system after becoming obsolete in the PC world. By 2008, both Virgin Atlantic and Qantas employed it for some of the onboard entertainment systems on long-distance jets. It also sees continued use as an embedded OS in retail cash tills. On July 14, 2013, Linux kernel version 3.11

1820-468: A liquidator. Details of the system include: Additional details: Microsoft Windows 3.1 Windows 3.1 is a major release of Microsoft Windows . It was released to manufacturing on April 6, 1992, as a successor to Windows 3.0 . Like its predecessors, the Windows 3.1 series run as a shell on top of MS-DOS ; it was the last Windows 16-bit operating environment as all future versions of Windows had moved to 32-bit . Windows 3.1 introduced

1911-459: A little more expensive compared to desktops, as the miniaturized components for laptops themselves are expensive. Notebook computers such as the TRS-80 Model 100 and Epson HX-20 had roughly the plan dimensions of a sheet of typing paper ( ANSI A or ISO A4 ).

2002-708: A microprocessor, the Intel 8008 . It was built starting in 1972, and a few hundred units were sold. This had been preceded by the Datapoint 2200 in 1970, for which the Intel 8008 had been commissioned, though not accepted for use. The CPU design implemented in the Datapoint 2200 became the basis for x86 architecture used in the original IBM PC and its descendants. In 1973, the IBM Los Gatos Scientific Center developed

2093-481: A new naming scheme: devices without an integrated phone are called Windows Mobile Classic instead of Pocket PC, while devices with an integrated phone and a touch screen are called Windows Mobile Professional. Palmtop PCs were miniature pocket-sized computers running DOS that first came about in the late 1980s, typically in a clamshell form factor with a keyboard. Non-x86 based devices were often called palmtop computers, examples being Psion Series 3 . In later years

2184-451: A new, incompatible version of Modular Windows ("1.1") shortly after the VIS shipped. No products are known to have actually used Modular Windows 1.1. The VIS was not a successful product; by some reports Radio Shack only sold 11,000 units during the lifetime of the product. Radio Shack store employees jokingly referred to the VIS as "Virtually Impossible to Sell". Tandy discontinued the product in early 1994 and all remaining units were sold to

2275-406: A preview of features that would later become staples of personal computers: e-mail , hypertext , word processing , video conferencing , and the mouse . The demonstration required technical support staff and a mainframe time-sharing computer that were far too costly for individual business use at the time. Early personal computers‍—‌generally called microcomputers‍—‌were often sold in

2366-475: A printer or to run Windows on a network, additional 2.5 MB of free space will be needed on the hard drive. The amount of RAM is dependent on software that runs on the PC; if the user is on the network and if the network requires a lot of memory, more RAM will be needed. Windows 3.1 includes more drivers for printers than its predecessor. It is also possible to connect to a network using Windows 3.1 via Hayes , Multi-Tech, or Trail Blazer modems. Windows 3.1

2457-499: A protocol used for sharing files and printers over local networks . It introduced support for the NetBEUI protocol. The price sat at $ 69 for Windows 3.1 users. The other version, Windows for Workgroups 3.11, was released on November 8, 1993. It was codenamed Snowball, and it introduced support for 32-bit file access , drive sharing, and group calendaring. It also has built-in fax capabilities. It received network improvements;

2548-600: A shared mainframe computer system was demonstrated as early as 1973 in the Community Memory project, but bulletin board systems and online service providers became more commonly available after 1978. Commercial Internet service providers emerged in the late 1980s, giving public access to the rapidly growing network. In 1991, the World Wide Web was made available for public use. The combination of powerful personal computers with high-resolution graphics and sound, with

Microsoft also built Microsoft Bob , a utility that would act as a search assistant, on Windows 3.1, only for it to be released on Windows 95 in 1995. The introduction of Windows Registry , a centralized database that could store configuration information and settings for various operating systems components and applications, also occurred in this version. The Control Panel also received changes; its items were now hard-coded , and additional items could be added by placing additional .cpl files. Similarly,

3276-411: Is considered to be an improvement on its predecessors. It was praised for its reinvigoration of the user interface and technical design. Windows 3.1 sold over three million copies during the first three months of its release, although its counterpart Windows for Workgroups was noted as a "business disappointment" due to its small amount of sold copies. It was succeeded by Windows 95 , and Microsoft ended

3367-497: Is considered to be more stable and multimedia-friendly in comparison with its predecessor, while its user interface was reinvigorated. It has been shown as an improvement, and it possesses more features in comparison with its rival IBM OS/2 2.0 , which launched a month earlier than Windows 3.1. InfoWorld rated the operating environment a "very good" value. Windows for Workgroups received lukewarm reception; it has been praised for its technical design, but it has been also noted as

3458-466: Is most often proprietary, or free and open-source software , which is provided in ready-to-run , or binary form. Software for personal computers is typically developed and distributed independently from the hardware or operating system manufacturers. Many personal computer users no longer need to write their programs to make any use of a personal computer, although end-user programming is still feasible. This contrasts with mobile systems, where software

3549-400: Is often available only through a manufacturer-supported channel, and end-user program development may be discouraged by lack of support by the manufacturer. Since the early 1990s, Microsoft operating systems (first with MS-DOS and then with Windows ) and Intel hardware – collectively called Wintel – have dominated the personal computer market, and today the term PC normally refers to

3640-442: Is typically used for tasks such as word processing , internet browsing , email , multimedia playback, and gaming . Personal computers are intended to be operated directly by an end user , rather than by a computer expert or technician . Unlike large, costly minicomputers and mainframes , time-sharing by many people at the same time is not used with personal computers. The term home computer has also been used, primarily in

3731-527: The Apple I computer circuit board, which was fully prepared and contained about 30 chips. The Apple I computer differed from the other kit-style hobby computers of era. At the request of Paul Terrell , owner of the Byte Shop , Jobs and Wozniak were given their first purchase order, for 50 Apple I computers, only if the computers were assembled and tested and not a kit computer.

The Heathkit H11 model was released in 1978 and was one of the first 16-bit personal computers; however, due to its high retail cost of $ 1,295 was discontinued in 1982. During the early 1980s, home computers were further developed for household use, with software for personal productivity, programming and games. They typically could be used with

5278-673: The common people] and help with our income-tax and book-keeping calculations. But this is speculation and there is no sign of it so far. In the history of computing , early experimental machines could be operated by a single attendant. For example, ENIAC which became operational in 1946 could be run by a single, albeit highly trained, person. This mode pre-dated the batch programming, or time-sharing modes with multiple users connected through terminals to mainframe computers. Computers intended for laboratory, instrumentation, or engineering purposes were built, and could be operated by one person in an interactive fashion. Examples include such systems as

5369-475: The first single-chip microprocessor , the Intel 4004 , in 1971. The first microcomputers , based on microprocessors, were developed during the early 1970s. Widespread commercial availability of microprocessors, from the mid-1970s onwards, made computers cheap enough for small businesses and individuals to own. In what was later to be called the Mother of All Demos , SRI researcher Douglas Engelbart in 1968 gave

5733-507: The introduction of the IBM PC, portable computers consisting of a processor, display, disk drives and keyboard, in a suit-case style portable housing, allowed users to bring a computer home from the office or to take notes at a classroom. Examples include the Osborne 1 and Kaypro ; and the Commodore SX-64 . These machines were AC-powered and included a small CRT display screen. The form factor

5824-549: The keyboard. These displays were usually small, with 8 to 16 lines of text, sometimes only 40 columns line length. However, these machines could operate for extended times on disposable or rechargeable batteries. Although they did not usually include internal disk drives, this form factor often included a modem for telephone communication and often had provisions for external cassette or disk storage. Later, clamshell format laptop computers with similar small plan dimensions were also called notebooks . A desktop replacement computer

5915-432: The late 1970s and 1980s. The advent of personal computers and the concurrent Digital Revolution have significantly affected the lives of people. Institutional or corporate computer owners in the 1960s had to write their own programs to do any useful work with computers. While personal computer users may develop their applications, usually these systems run commercial software , free-of-charge software (" freeware "), which

Microsoft ended its support for Windows 3.1 and Windows for Workgroups on December 31, 2001, although the embedded version of Windows for Workgroups 3.11 was retired on November 1, 2008. The operating environment was superseded by Windows NT 3.1 , which was released in 1993, and Windows 95 in 1995. The installer of the beta release used code that checked whether it

6188-403: The old system and driver updates. The need for the continued use of Windows 3.11 could apparently be traced back to Siemens ' SIBAS (Siemens Bahn Automatisierungs System) automation system used to control trains. The job post was retracted due to "unfortunate wording". Personal computer A personal computer , often referred to as a PC , is a computer designed for individual use. It

6279-503: The primary defining characteristic of netbooks was the lack of an optical disc drive, smaller size, and lower performance than full-size laptops. By mid-2009 netbooks had been offered to users "free of charge", with an extended service contract purchase of a cellular data plan. Ultrabooks and Chromebooks have since filled the gap left by Netbooks. Unlike the generic Netbook name, Ultrabook and Chromebook are technically both specifications by Intel and Google respectively. A tablet uses

Microsoft also provided WinG , an application program interface, to entice developers to move from DOS to Windows. It also provided a device-independent interface to graphics and printer hardware, and allowed programs to have both read and write capabilities to the WinGDC. Unlike all previous versions, Windows 3.1 could not run in real mode and it insisted on

6734-561: The ubiquitous Wintel platform. Alternatives to Windows occupy a minority share of the market; these include the Mac platform from Apple (running the macOS operating system), and free and open-source , Unix-like operating systems, such as Linux . Other notable platforms until the 1990s were the Amiga from Commodore , and the PC-98 from NEC . The term PC is an initialism for personal computer. While

6825-401: The use of 80286 processors or above. Because of this, the maximum memory available was increased. While Windows 3.0 was limited to 16 MB maximum memory, Windows 3.1 could access a theoretical 4 GB in the 386 enhanced mode. The actual practical ceiling is 256 MB. Like its predecessors, it runs as a 16-bit system; Windows 3.1 is also the last Windows to run in 16-bit mode. It

6916-548: Was also added, while Object Linking and Embedding, which was implemented in Windows 3.1, was also included in the Windows for Workgroups version. The Workgroups version also introduced the Microsoft Mail program, which allowed users to receive and send email , and Microsoft Schedule+ , a time management app. Windows for Workgroups could also be accessed from an OS/2 client that uses the Server Message Block (SMB),

7007-410: Was also introduced in this version. File Manager had also received tweaks; split view-mode was introduced, users were now able to browse files without having to open separate windows, while files were able to be dragged and dropped to other locations on the system. An option for quick formatting was introduced to format floppy disks and copy its files without having to quit Windows. File Manager

7098-500: Was apparent early on. Alan Kay described the Dynabook in 1972, but no hardware was developed. The Xerox NoteTaker was produced in a very small experimental batch around 1978. In 1975, the IBM 5100 could be fit into a transport case, making it a portable computer, but it weighed about 50 pounds. Such early portable computers were termed luggables by journalists owing to their heft. Before

7189-681: Was back-ordered and not available until later that year. Three months later (April), the Apple II (usually referred to as the Apple) was announced with the first units being shipped 10 June 1977, and the TRS-80 from Tandy Corporation / Tandy Radio Shack following in August 1977, which sold over 100,000 units during its lifetime. Together, especially in the North American market, these 3 machines were referred to as

7280-429: Was designed to be controlled via television . It was a special version of Windows 3.1, which was designed to run on Tandy Video Information System ; it allowed users to run multimedia software without having to buy a personal computer. It also contained a software development kit (SDK) for programmers to write applications that would run on devices that have Modular Windows. The SDK was sold for $ 99. Modular Windows

7371-469: Was discontinued in 1994. Released on November 8, 1993, Windows 3.11 was introduced with fixes for network problems which were present on Windows 3.1. As a minor update, new features were not present in this version. It also did not run on IBM's OS/2 for Windows. Windows 3.11 allowed users to connect to each other as peers to share the resources of their computers. Microsoft replaced all retail and OEM versions of Windows 3.1 with Windows 3.11 and provided

7462-401: Was intended to allow these systems to be taken on board an airplane as carry-on baggage, though their high power demand meant that they could not be used in flight. The integrated CRT display made for a relatively heavy package, but these machines were more portable than their contemporary desktop equals. Some models had standard or optional connections to drive an external video monitor, allowing

7553-418: Was introduced as a product for users to remotely access Windows NT and its Advanced Server networks. It runs in 80386 enhanced mode, and it supports the use of network redirectors . It was sold in two versions; the complete package cost $ 219 while the "Workgroup Add-on for Windows" cost $ 69 . The official system requirements for Windows 3.1 and subsequent versions include the following: To use

7644-419: Was introduced in November 1992 as a reaction to Apple 's QuickTime technology. At the price of $ 200, the software included editing and encoding programs. It was later built into Windows 95 . Microsoft also published Windows for Pen Computing , a pen computing interface which was created in response to PenPoint OS by GO Corporation . The operating environment was also given limited compatibility with

7735-600: Was introduced with more language support, while Tandy Video Information System received a special version, called Modular Windows. In November 1993, Windows 3.11 was released as a minor update, while Windows 3.2 was released as a Simplified Chinese version of Windows 3.1. Microsoft also introduced Windows for Workgroups, the first version of Windows to allow integrated networking . Mostly oriented towards businesses , it received network improvements and it allowed users to share files, use print servers, and chat online, while it also introduced peer-to-peer networking. The series

7826-502: Was officially named "Linux For Workgroups" as a tongue-in-cheek reference to Windows for Workgroups 3.11. In November 2015, the failure of a Windows 3.1 system in Orly Airport in Paris, which was responsible for communicating visual range information in foggy weather to pilots, made operations temporarily cease. Whether the failure was hardware- or software-based is not specified, though

7917-573: Was open to shipping Tandy Sensation PCs with the Windows 3.1 operating environment. IBM and its PCs were also provided with Windows 3.1. Further enhancements were introduced in Windows 3.1. The TrueType font system was introduced to provide scalable fonts to Windows applications, without having to resort on using third-party technology such as Adobe Type Manager (ATM). Windows 3.1 introduced Arial , Courier New , and Times New Roman fonts, in regular, bold, italic, and bold-italic versions, which could be scaled to any size and rotated, depending on

8008-595: Was running on Microsoft-licensed DOS or another DOS operating system, such as DR-DOS . It was known as AARD code, and Microsoft disabled it before the final release of Windows 3.1, though without removing it altogether. Digital Research , who owned DR-DOS, released a patch within weeks to allow the installer to continue. Memos that were released during the United States v. Microsoft Corp. antitrust case in 1999 revealed that Microsoft specifically focused it on DR-DOS. When Caldera bought DR-DOS from Novell , they brought

8099-453: Was the 1973 Xerox Alto , developed at Xerox 's Palo Alto Research Center (PARC) . It had a graphical user interface ( GUI ) which later served as inspiration for Apple's Macintosh , and Microsoft's Windows operating system. The Alto was a demonstration project, not commercialized, as the parts were too expensive to be affordable. Also in 1973 Hewlett Packard introduced fully BASIC programmable microcomputers that fit entirely on top of

8190-490: Was the first to emulate APL/1130 performance on a portable, single user computer, PC Magazine in 1983 designated SCAMP a "revolutionary concept" and "the world's first personal computer". This seminal, single user portable computer now resides in the Smithsonian Institution , Washington, D.C.. Successful demonstrations of the 1973 SCAMP prototype led to the IBM 5100 portable microcomputer launched in 1975 with

8281-597: Was the first version of Windows that was suitable for integrated networking . Initially developed as an add-on for Windows 3.0, it was later released in 1992. It introduced drivers and protocols for peer-to-peer networking. Windows for Workgroups was mostly oriented towards businesses . The first version of Windows for Workgroups, 3.1, was released on October 27, 1992. Codenamed Winball and Sparta, it allows users to share files , use print servers , and chat online ; files could be accessed from other machines that run either Windows or DOS.
