Introduction

The basic parts of a desktop computer are the computer case,monitor, keyboard, mouse,

and power cord. Each part plays animportant role whenever you use a computer.

Computer Case

A computer case

The computer case is the metal and plastic box that contains the main components of the

computer. It houses the motherboard, central processing unit (CPU), the power supply, and

more.

Computer cases come in different shapes and sizes. A desktop case lies flat on a desk, and the

monitor usually sits on top of it. A tower case is tall and sits next to the monitor or on the

floor. The front of the case usually has an on/off switchand one or more optical drives.

Most of the personal computers you can purchase today include tower cases, rather than

desktop cases; however, some computers are being made with all of the internal components

built into the monitor, which completely eliminates the tower.

Monitor

The monitor works with a video card, located inside the computer case, to display

images and text on the screen. Newer monitors usually have LCD (liquid crystal

display) or LED (light-emitting diode) displays. These can be made very thin, and they

are often called flat panel displays. Older monitors use CRT (cathode ray tube)

displays. CRT monitors are much bigger and heavier, and they take up more desk

space.

Most monitors have control buttons that allow you to change your monitor's display

settings, and some monitors also have built-in speakers.

LED displays are actually LCD displays that are backlit with light-emitting diodes.

This allows for greater contrast than a traditional LCD display.

Keyboard

The keyboard is one of the primary ways we communicate with the computer and enter

data. There are many different types of computer keyboards such as wired, wireless,

ergonomic, multimedia, and more. Although there may be differences in the location of

some keys or features, keyboards are very similar and allow you to accomplish

basically the same tasks.

Mouse

Page 3: Introduction · Traditionally, a mouse connects to the computer using a USB orPS/2 connection. However, you can also buy a wireless mouse, which can reduce clutter on your desktop.

The mouse is a peripheral that is known as a pointing device. It lets you point to

objects on the screen, click on them, andmove them.

There are two main types of mice: optical and mechanical. Theoptical mouse uses an

electronic eye to detect movement and is easier to clean. The mechanical mouse uses a

rolling ball to detect movement. Generally, a mechanical mouse is cheaper, although it

may require regular cleaning to keep it working properly.

Traditionally, a mouse connects to the computer using a USB orPS/2 connection.

However, you can also buy a wireless mouse, which can reduce clutter on your

desktop.

Mouse Alternatives

There are other devices that can do the same thing a mouse can do, but with a different

look and feel. Many people find them to be easier to use, and they also require less

desk space than a mouse. The most common mouse alternatives include:

Trackball: A trackball has a ball on top that can rotate freely. Instead of moving

the device like a mouse, you can simply roll the ball with your fingers to move the

pointer. Some mobile devices have miniature trackballs that can be controlled

with your thumb.

Touchpad: A touchpad (also called a trackpad) is a touch-sensitive pad that lets

you control the pointer by making a "drawing" motion with your finger.

Touchpads are very common on laptop computers.

A computer is an electronic machine that processes data. Information given to the computer is

called data. Computer works very fast. It saves your time and energy. It does not make mistakes.

It can remember a lot of things. The basic parts of a computer are shown in the picture given

here.

Page 4: Introduction · Traditionally, a mouse connects to the computer using a USB orPS/2 connection. However, you can also buy a wireless mouse, which can reduce clutter on your desktop.

These parts of the Computer and some other devices are connected together with the help of

wires and cables.

The basic parts of a computer system are:

1. Monitor

2. CPU (Central Processing Unit)

3. Keyboard

4. Mouse

5. Speakers

6. Printer

Let us find out about some more devices that can be connected to a computer.

Input Devices:

Devices that help us put data into the computer are called input devices. They help in giving

instructions to the computer. Let us learn about a few input devices.

Keyboard:

The keyboard is used for entering data into the computer system. It can type words, numbers and

symbols. More information of computer keyboard Click here.

Mouse:

The mouse is a pointing device. You can give input to the computer with the help of the mouse.

Joystick:

A joystick makes computer games a lot more fun. When it is moved, it passes information to the

computer.

Microphone:

A microphone is the mike that can be attached to a computer. It allows you to input sounds like

speech and songs into the computer. You can record your voice with the help of a microphone.

Scanner:

A Scanner Copies pictures and pages, and turns them into images that can be saved on a

computer.

Processing Device:

All the inputs are stored, sorted, arranged and changed by a computer. The device that helps a

computer do so is called the processing device. The processing device in a computer is known

as Central Processing Unit (CPU).

Output Devices:

The parts of a computer that help us to show the results of processing are called out devices. Let

us learn about a few output devices.

You can listen to music or any sound from a computer with the help of headphones without

disturbing others.

Storage Devices:

The parts of a computer which are used for storing data are called. Storing data are called storage

devices. They help in storing any work done on a computer permanently. Let us learn about a

few storage devices.

Hard Disk:

Inside the CPU there is a hard disk. It is made up of one or more metallic disks. It stores a large

amount of information.

Floppy Disk:

A floppy disk stores small amounts small amounts of information. It works when it is inserted

into the floppy drive. The floppy drive is fixed in the CPU.

Compact Disc (CD):

A CD stores many times more information than a floppy disk. It works when it is inserted into

the CD drive. The CD drive is fixed in the CPU. Note: Not handling the CD properly may result

in loss of data stored.
