Satisfactory Essays

The motherboard is the most important component within a PC system.
A motherboard is the main printed circuit board found in computers. It holds many of the crucial electronic components of the system, such as the CPU and memory and provides connectors for other peripherals.
The form factor defines whereabouts the components are positioned on the motherboard and how it is mounted within the chassis.
Various form factors exist for motherboards.
AT – Advanced Technology
ATX – Advanced Technology Extended
Mini-ATX – Smaller footprint of ATX
Micro-ATX – Smaller footprint of ATX
LPX – Low-profile Extended
NLX – New Low-profile Extended
BTX – Balanced Technology Extended
Families of Motherboards:
•A backplane mainboard provides a number of card slots into which other cards (daughterboards) can be fitted – this allows processors and memory circuit cards to be put together to create particular capability.
•A motherboard-style mainboard – unlike a backplane, a motherboard contains significant subsystems such as the processor.
Two types of backplane mainboards:
A passive backplane provides a simple bus structure and limited data buffering
An active backplane provide chips which buffer the various signals to the slots.
BIOS = Basic Input/Output Systems
The BIOS is a collection of software utilities that forms part of the operating system
Being on ROM, the BIOS is not affected by power failure and makes it possible for the computer to boot itself
The POST (power on self test) is a
