Battery
t5v
supply power to CMOS
Chipset
South Bridge
For low speed process
Ex. Keyboard, USB
North bridge
For high speed process
Ex. RAM, Graphic
Resources request
DMA
Faster performance
Interrupt
IRQ no. issue to all hardware
Crystal (for accurate)
For clocking/timing
Cache memory
store program instruction
RAM
SRAM
Faster ROM chip access
DRAM
Information will face if capacitator not recharge
volatile
requires power to maintain the stored information
it retains its contents while powered on but when the power is interrupted, the stored data is gone
ROM
Non-volatile
can retrieve stored information even if power off
EPROM
erased by using strong ultraviolet light source
EEPROM
allows individual bytes to be erased and reprogram by using electricity
