The document discusses several key components of a computer system: The CPU carries out computer program instructions by performing basic arithmetic, logical, control and input/output operations. The monitor displays information visually and includes a display, circuitry, casing and power supply. The mouse is a pointing device that detects motion relative to a surface and translates it into pointer movement on screen. The keyboard uses buttons or keys to act as mechanical levers or electronic switches for input. Additional components include the computer case, cooling fans, RAM and ROM for data storage and processing. Overall, computers add speed, accuracy and convenience while making important contributions across many fields.

1. Some parts of computer and its
importance

2. CPU
is the electronic
circuitry within
a computer that carries out
the instructions of
a computer program by
performing the
basic arithmetic, logical,
control and input/output (I/O)
operations specified by the
instructions.

3. Monitor
is an output device which
displays information in
pictorial form. A monitor
usually comprises
the display
device, circuitry, casing,
and power supply.

4. Mouse
is a pointing device (hand
control) that detects two-
dimensional motion
relative to a surface. This
motion is typically
translated into the motion
of a pointer on a display,
which allows a smooth
control of the graphical
user interface.

5. Keyboard
is a typewriter-style
device which uses an
arrangement of buttons
or keys to act as
a mechanical
lever or electronic switch.
Following the decline
of punch cards and paper
tape, interaction
via teleprinter-style
keyboards became the
main input
device for computers.

6. Case
A computer case, also
known as a computer
chassis, tower, system
unit, cabinet, base unit,
or simply case, is the
enclosure that contains
most of the components
of a computer (usually
excluding the display,
keyboard and mouse).

7. Computer fan
is any fan inside, or
attached to, a computer
case used for active
cooling, and may refer to
fans that draw cooler air
into the case from the
outside, expel warm air
from inside, or move air
across a heat sink to cool
a particular component.

8. RAM and ROM
RAM ROM

9. are everywhere! They help us with calculations,
storing data, staying organized and also
entertain and inform us.
Computers add speed and accuracy in various
methods and so, they help us save time and
money too!
Computers have made important contributions
in various fields including science, technology,
education, society and many more!

10. Computers can be defined as electronic devices that
receive, store and process the input data to generate the
right output. In order to receive the right and desired
output, one should enter the right information or data in
computers.
Computers process various types of data, which is
entered by users. These electronic devices execute a
number of programs to achieve the correct result.
Computers also act as highly reliable scientific equipment.
They receive and store data and carries out logical and
mathematical calculations too to provide fast and accurate
results. These days, computers are used in various fields
and at almost every place!

11. Computer is one of the best gifts of
technology! They are a pack of
entertainment, information, knowledge and
intelligence. Undoubtedly, computers have
made significant contribution in human life
and progress, but we suggest that one
should not become a slave of technology!
What we exactly mean to say is that we
should spend time in front of screen with a
purpose and meaning and that, we should
always remember that the real world lies off-
screen!
