Computer and Information Technology for HKCEE
Assembling the Hardware
Choose the right combination of hardware
e.g. Home use and web surfing
LAN card or modem is needed
no need to install sophisticated hardware
Cost considerations
never go for CPU with the highest speed
choose a hard disk with appropriate capacity
consider reputation and warranty
Precautions in computer assembling
Discharge oneself before handling hardware
Hold the main board and expansion cards by edges
Return the main board and peripherals to anti-static bags
Disconnect the power before working on the system
