There are four types of input into a computer system: text, graphics, audio, and video. Input devices like keyboards, mice, and cameras are used to enter these different types of data. The processing unit, like the CPU, controls all activities in the system and processes the input. The output of processed data comes in four forms: text, graphics, audio, and video. Output devices such as monitors and speakers are used to convey the processed information to the user. Storage holds data, instructions, and information for future use and comes in two types: primary storage like RAM and secondary storage like hard disks.

2. Input is any data or instructions that we enter into the
computer system for processing. There are four types of
input: which are text, graphic, audio and video. Example of
input devices are keyboard, light pen, joystick, microphone,
mouse, video & digital camera

3. The processing unit controls all activities within the system. The CPU
is an example of a processor. It has the same important as the brain
to human being.

4. Output is data that has been processed into a useful form,
called information. There are four types of output, which
are texts, graphics, audio and video. Example of output
devices are monitor, printer, speaker and plotter.

5. Storage is a location which data, instruction and
information are held for future use. It is the physical
material that keeps data, instruction and information. There
are two types of storage. They are the primary storage and
secondary storage. The example of storage devices are
hard disk, Floppy Disk, diskette, RAM, CD ROM and DVD
ROM.

7. EXAMPLE :

8. Users input data or instruction into the computer system to
be process. Input could be either text, graphic, audio or
video. Input devices are used by users to input data. Input
devices are any electronic device connected to a computer
and produces input signals.

9. Data or instruction being input into the computer system is
then processed by the CPU which controls all activities
within the system. The results of the processed data are
then sent to an output device as usable data . A CPU
interprets the and carries out the instructions by processing
data and controlling the rest of the computer’s components
. A CPU consists of two subcomponents; the Control Unit
(CU) and the Arithmetic Logic Unit (ALU). CU’s main
function is to direct the CPU to process data by extracting
instructions from memory and decodes and executes them.
The CU manages a four-step basic operation which is called
a machine cycle. The steps are Fetching, Decoding,
Executing & Storing:

10. Computer storage is important to help users store
programs and data to be used at a later time. It is also
useful to keep current data while being processed by the
processor until the information is saved in a storage media
such as a hard disk or a diskette. Computer storage also
stores instructions from a computer program. There are
two type of computer storage; primary storage and
secondary storage.
