Graphics - Video card

The graphics card - otherwise called a graphics adapter, video adapter, or video card - processes and renders the graphics output from the computer to the VDU or computer monitor and is an essential part of the modern computer. On older and budget models graphics cards tended to be integrated with the motherboard but, more commonly, they are supplied in PCI, AGP, or PCI Express format. Graphic cards are also the most glamorised computer component as it is the component which creates all the visual effects on the computer which is essential for playing games.

Laptop computers

A laptop computer or simply laptop (also notebook computer or notebook) is a small personal computer designed for mobility. Usually all of the peripherals needed to operate the laptop are built in to a single unit. Most laptops contain batteries to facilitate operation without a readily available electrical outlet.

Non IBM-compatible personal computers

Though many personal computers are IBM PC compatible using either Microsoft Windows or closed and open-source Unix-likes such as Linux, a number of other personal computer types are also popular.

A leading alternative to the IBM PC is the Apple Macintosh, a combination of proprietary hardware and operating system. The Macintosh orignally used the Motorola 68000 series, then shifted to the IBM and Motorola PowerPC processors.

In January 2006, Apple shifted its architecture to the same Intel chip found in IBM compatibles, allowing their computers to run Apple's own Mac OS X as well as other IBM PC Compatible Operating Systems.

Further PC and PW (Personal Workstation) types through time:

• Amiga (previously produced by Commodore, now under license from Amiga Inc.)
• Acorn Archimedes & RiscPC
• Atari ST
• BeOS BeBox
• Pegasos
• NEC PC-9800 (At one time, in Japan)
• NeXT workstations
• Sun SPARCstation
• SGI workstations like the SGI Indigo and SGI Onyx The term "personal computer" is often avoided by advocates of the above computer systems, ostensibly because of the association it has to the "PC" in "IBM PC".
