THE CPU..This is the most important component of a computer system. It is the brain of the
computer system and it determines the capacity of the computer system. All other hardware
component of computer system connects to Cpu in order to carry out instructions. These other
component cannot work on their own without cpu .
Main memory. .
It is the storage media on the motherboard. It is used to store data and instructions to be executed
by the cpu. Main memory is closer to the cpu than any secondary storage device.
SECONDARY STORAGE. .
secondary storage device is anon-volatile device that holds data until it is deleted or overwritten.
Secondary storage is about two orders of magnitude cheaper than primary storage. Consequently,
hard drives (a prime example of secondary storage) are the go-to solution for nearly all data kept
on today's computers.
INPUT DEVICE
It is a device that allow users to enter data and command into the computer system. Some of this
device are keyboard, mouse, trackball, etc.
OUTPUT DEVICE
An output device is a hardware that present digital information in a form that human being can
understand.
CONNECTING DEVICE..
Connecting devices are bridges between the different parts of a document that tie all of the pieces
together into one coherent package. Connecting devices show the reader how various sections of
information are related, and they help keep the reader o n track with the flow of information.
