Hardware Components of a
Computer System and their
Functions
Power supply unit
Power supply unit is a hardware component
that supplies power to other components inside the system
unit by converting an alternating current to a direct current
from standard wall outlets or directly from batteries.
SLOTS
Slots are physical connection points on a motherboard that
allow the hardware of a computer to be expanded.
Examples include RAM and Expansion cards.
