2. COMPONENTS OF A
COMPUTER
AND HOW IT WORKS

3. WHAT IS A COMPUTER?
A computer is an electronic device that manipulates
information, or data. It has the ability to store, retrieve,
and process data. You may already know that you can
use a computer to type documents, send email, play
games, and browse the Web.

4. COMPONENTS OF A COMPUTER
There are more then 20 components of a computer but 5 parts
are basic parts of a computer. We will talk about those parts
today. Those parts are
1. Motherboard
2. CPU
3. GPU
4. RAM
5. Storage

5. MOTHERBOARD
TThe motherboard of a computer is the circuit board on which all the basic
and high-end chipsets are installed. All the circuits installed on the
motherboard propel the working of a computer. The motherboard is one of
the main parts of a computer and is also known as the printed circuit board.
It is present in all computer systems,
be it the general-purpose systems or the expandable ones.
The main electronic components of a computer such as
its central processor, interface connectors,
memory controllers are all integrated into the motherboard.
The peripheral components, sound cards, hard drives,
interface cards, network cards, video cards, and cards
for extra USB slots, are attached to the motherboard.

6. CPU
• CsU or the Central Processing Unit is among the basic parts of computer and is
often referred to as the brain of the computer. All the data provided to a
computer is processed in the Central Processing Unit of the computer. The
instructions given to a
• computer through various computer programs are executed
• in this processor. The basic controlling, logical, arithmetic,
• and I/O operations are executed in the CPU. There are
• two components of a basic CPU, namely, the Arithmetic
• Logic Unit (ALU), and the Control Unit. All the arithmetic
• and logical operations are carried out in the ALU. The
• results of the arithmetic operations are stored in the processor. The Control

7. GPU
The Graphics Processing Unit is used as a co-processor to enhance the
performance of the Central Processing Unit in engineering and scientific
computing. It offloads some of the time-consuming parts of program codes, to
improve the performance of the CPU. The Graphics Processing Unit boosts the
CPU performance by providing a parallel processing facility. A GPU may contain
hundreds of cores, whereas a CPU contains a maximum of 8 cores. The highly
programmable feature of graphics chips led to the invention
of the Graphics Processing Unit. These cards
can directly communicate with the display
monitors. A graphics card comes with a
processing unit, a cooling mechanism,
connections to display devices, and a memory.

8. RAM
Random Access Memory or RAM refers to the volatile memory of a computer. It
is a very common topic covered in the chapter on the parts of computer for kids.
It is referred to as the main memory of the computer. RAM is one of the main
parts of computer and it stores the application programs, operating system, and
the data that is currently used. It takes a shorter time to read data from RAM
and to write data in it. Therefore, the processor of
a computer can access the data stored in the Random
Access Memory, in a short time. As stated above,
RAM is volatile in nature, that is, all the data
stored in it is lost when we turn off the computer.
So, every time we restart the computer the
operating system along with the other programs

9. STORAGE
• One of the basic parts of computer is constituted by its storage components.
The solid-state drive
• and the hard disk drive are the key storage components of a computer. The
hard disk drive of a
• computer system stores data permanently.
• Therefore, even if you turn off the computer,
• the data stored in the hard disk drive will be
• saved. All the important data, software programs,
• and operating systems are stored in the hard
• disk drive of a computer. Hard disk drives
• are secondary storage devices.

10. • Without these components there are also so many other components But
these are the basic components.
• There are some input and output components
• 1 Mouse
• 2 Keyboard
• 3 Microphone
• Many more
• These input and output device are why we can control a computer easily.

11. MOUSE
• The mouse is a small, movable device that lets you control a
range of things on a computer. Most types of mouse have two
buttons, and some will have a wheel in between the buttons.
Most types of mouse
• connect to the computer with a cable, and use
• the computer’s power to work.
• Some types of mouse are wireless.

12. KEYBOARD
• A computer keyboard is an input device used to enter characters and functions
into the computer system by pressing buttons, or keys. It is the primary device
used to enter text. A keyboard typically contains keys for individual letters,
numbers and special characters, as well as keys for specific functions. A
keyboard is connected to a computer system using a cable or a wireless
connection.

13. •Without these there are so many other
components. But these are common and
important parts/components of a
computer system
