Inside Computer Components
ENCLOSURE
The enclosure is the major and main element of a PC.
The enclosure (AT case) forms the mechanical foundation (chassis) of PC. Other sub-assembly is fitted securely to this chassis.
The chassis is electrically grounded through the power supply.
Grounding prevents discharge of static electricity from damaging other sub-assemblies.
POWER SUPPLY
The power supply is located in the rear right quarter of the enclosure.
Ac enters the supply through the ac line cord, which is connected at the rear of the enclosure.
A supply then produces a series of dc outputs that power the motherboard and drives.
MOTHERBOARD
The motherboard (also known as the main board, system board, backplane board, or planar board) holds the majority of a computer’s processing power.
A motherboard contains the system CPU, clock/timing circuits, RAM, cache, BIOS ROM, USB port(s), parallel port, and expansion slots.
