The first model looked like the later IBM PC ( which came on the market years later ), a rectangular base unit with two floppy drives on the front, and a monitor on top with a separate detachable keyboard.

In a typical central processing unit ( CPU ), PC is a binary counter ( which is the origin of the term program counter ) that may be one of many registers in the CPU hardware.

The 8051's predecessor, the 8048, was used in the keyboard of the first IBM PC, where it converted keypresses into the serial data stream which is sent to the main unit of the computer.

In 1994, Acorn used the ARM 610 as the main central processing unit ( CPU ) in their Risc PC computers.

This is even more apparent for PC users who are able to improve the specifications of the computer by upgrading parts such as the graphics card, processor unit and RAM modules.

An Apollo workstation resembled a modern PC, with base unit, keyboard, mouse, and screen.

The 3DMark measurement unit is intended to give a normalized mean for comparing different PC hardware configurations ( mostly graphics processing units and central processing units ), which proponents such as gamers and overclocking enthusiasts assert is indicative of end-user performance capabilities.

The main parts of an X-ray Baggage Inspection System are the generator used to generate x-rays, the detector to detect radiation after passing through the baggage, signal processor unit ( usually a PC ) to process the incoming signal from the detector, and a conveyor system for moving baggage into the system.

The unit was designed with a Game Boy-specific slot on the top of the unit and took 6 AAA batteries or a 9V adapter for power, and it connected to a PC via a parallel port.

In the 2009 PC game Empire: Total War, the Puckle Gun is available as a unit in the late 18th century.

* In the PC games Medieval: Total War and Medieval II: Total War the Varangian Guard is an axe-wielding elite infantry unit of the Byzantine Empire.

Asus is the world's fifth-largest PC vendor by 2011 unit sales ( after HP, Lenovo, Dell and Acer ).

When connected to a PC, " PC -- MD " appears on the Hi-MD device's display to indicate the unit is connected in PC — MD mode.

In PC — MD mode, pressing Play on the unit, for example, results in " PC -- MD " flashing, indicating this function cannot be activated from the device when connected to the computer.

PC — MD status is constant as long as the unit is connected via USB cable ( regardless of whether SonicStage is running or not ).

The cradle is used for both charging and synchronizing the Palm's data to a PC ( software is included for Windows and Mac OS X, but with the pilot-link software, the unit synchronizes perfectly with a Unix operating system ).

* CD: The SuperGrafx was compatible with the PC Engine Super CD-ROM² unit, and could play all PC-Engine CD games with it attached.

* In the PC strategy game Empire Earth, the Japanese special unit, the Cyber Ninja, has an attack called " Logic Bomb ".

The Amiga brand was then sold to another PC manufacturer, Gateway 2000, which had announced grand plans for it.

The original AIX ( sometimes called AIX / RT ) was developed for the IBM 6150 RT workstation by IBM in conjunction with Interactive Systems Corporation, who had previously ported UNIX System III to the IBM PC for IBM as PC / IX.

In the meantime IBM had released its original IBM PC, which incidentally looked remarkably like the Asters base with floppy drives + separate keyboard set-up.

By the mid-1990s, however, companies were beginning to ask what the return was on the investment they had made in this loosely controlled PC software buying spree.

PC style subdirectories were rejected as being too difficult to work with in terms of Block Allocation Maps, then still much in vogue, and which for some time had been the traditional way of inquiring into block availability.

By the late 1980s, the personal computer market had become dominated by the IBM PC and Apple Macintosh platforms.

By this point, both the IBM PC and Apple Macintosh had a much larger market share than the Amiga platform.

Two key marketing executives in Compaq's early years, Jim D ' Arezzo and Sparky Sparks, had come from IBM's PC Group.

Rosen and Canion had disagreed about how to counter the cheaper Asian PC imports, as Canion wanted Compaq to build lower cost PCs in-house, while Rosen believed that Compaq needed to buy standard components from suppliers and reach the market faster.

While rival Dell Computer had 55 % growth in U. S. PC sales in the first quarter of 1999, Compaq could only manage 10 %.

Capellas was able to restore some of the luster lost in the latter part of the Pfeiffer era and he repaired the relationship with Microsoft which had deteriorated under his predecessor's tenure, but the company still struggled against lower-cost competitors such as Dell who took over the top spot of PC manufacturer from Compaq in 2001.

By the mid-1990s, Compaq's price war had enabled it to overtake IBM and Apple, while other IBM PC Compatible manufacturers such as Packard Bell and AST were driven from the market.

An Ethernet adapter card for the IBM PC was released in 1982 and by 1985, 3Com had sold 100, 000.

The PC / AT, introduced in 1984, had three 8-bit slots and five 16-bit slots, all running at the system clock speed of 6 MHz in the earlier models and 8 MHz in the last version of the computer.

Sams related the story to Gates, who had already agreed to provide a BASIC interpreter and several other programs for the PC.

Although we were competitors, I always had tremendous respect for his contributions to the PC industry.

In 1983, Microsoft announced the development of Windows, a graphical user interface ( GUI ) for its own operating system ( MS-DOS ), which had shipped for IBM PC and compatible computers since 1981.

Windows / 386 2. 1 had a protected mode kernel with LIM-standard EMS emulation, the predecessor to XMS which would finally change the topology of IBM PC computing.

They cooperated with each other in developing their PC operating systems, and had access to each other's code.

As the 1980s began, hard disk drives were a rare and very expensive additional feature on personal computers ( PCs ); however by the late ' 80s, their cost had been reduced to the point where they were standard on all but the cheapest PC.

The 80286 provided built in memory protection mechanisms which had been almost exclusive to mainframes and minicomputers ( CPUs like the NS320xx and M68000 needed additional components in order to implement MMU functions ) and the large performance enhancements represented by the 80286 and many of its successors would pave the way for the x86 and the IBM PC architecture to extend from low performance personal computers all the way to high-end workstations and servers and even drive the market for other architectures.

Despite their work, Nintendo turned them down, saying they had no interest in expanding to the PC market, and that Mario games were to remain exclusive to Nintendo consoles.

The K6 had a considerable impact on the PC market and presented Intel with serious competition.
