The spine of the computer is the motherboard, otherwise known as the system board or mainboard. |
System Board Form FactorsSystem boards are classified by their form factor (design), such as ATX, micro ATX, and ITX. |
PCA personal computer PC is a computing device made up of many distinct electronic components that all function together in order to accomplish some useful task, such as adding up the numbers in a spreadsheet or helping you write a letter. |
Advanced Technology ExtendedIntel developed the Advanced Technology Extended (ATX) motherboard in the mid-1990s to improve upon the classic AT-style motherboard architecture that had ruled the PC world for many years. |
Micro ATXA form factor that is designed to work in standard ATX cases, as well as its own smaller cases, is known as micro ATX (also referred to as uATX).Micro ATX follows the ATX principle of component placement for enhanced cooling oer pre-ATX designs but with a smaller footprint. |
ITXThe ITX line of motherboard form factors was developed by VIA as a low-power, small form factor (SFF) board for specialty uses, such as home-theater systems and embedded components. |
Bus ArchitectureThe term bus is also used in any parallel or bit-serial wiring implementation where multiple devices can be attached at the same time in parallel or in series (daisy-chained). |
ChipsetsA chipset is a collection of chips or circuits that perform interface and peripheral functions for the processor. |
NorthbridgeThe Northbridge subset of a motherboard's chipset is the set of circuitry or chips that performs one very important function: management of high-speed peripheral communications. |
SouthbridgeThe Southbridge subset of the chipset is responsible for providing support to the sower onboard peripherals (PS/2, parallel ports, serial ports, Serial and Parallel ATA, and so on), managing their communications with the rest of the computer and the resources given to them. |
