5. BIOS (Basic Input/Output System)

- considered a ROM

- perform POST (Power On Self Test).

- responsible for operating the computer until loading OS.

- responsible for recognizing any new hardware.

- responsible for the basic input and output operations.

- PHOENIX , AWARD

7. PCI slots and AGP slot

- AGP :Accelerated Graphics Port

- PCI :Peripheral Component Interconnect

- for connecting various cards

( sound, fax and VGA cards ).

- Sound and VGA cards may be built-in

Adv:- Sheep

Dis:-

- sound card : no problem

- VGA card : needs its own memory, it will be from main memory
