Interesting Uses of Computers

A pilot uses the computer to fly safely.
He can check the direction his plane is
flying. He can find out if the weather is
safe for flying. He can tell if other planes
are flying in his direction.
A doctor uses the computer to check

if her patient is sick. A special
machine lets her see inside her
patient’s body. The pictures shown by
the computer tell her what is wrong
with the patient.
A computer is really great! It is useful in many

places. Do you know of other uses of our friend
—the computer?
SECTION 2 Getting to Know the Computer
In this section, we will know more about

computers. We will find out that there are
different types of computers. They each
have a different purpose.
LESSON 4: Computers, Big and Small
1.Identify the different

types of computers
2.Explain the purpose of

each type
Computers come in different shapes and sizes
Not all computers have a screen that looks like a

TV screen and has a keyboard where you can
type
Mainframe Computer
This type of computer is used by large
companies to service their customers. For
example, ATM machines in the country are
linked to their bank’s powerful mainframe
computers.
Minicomputer
This minicomputer is smaller than a
mainframe. It is larger than the computer you
have at home. It is used by medium-sized
companies. It can store all the data that is
needed by a small company.

Microcomputer
The microcomputer is the most common type of
computer. You might have one at home. You also
see many of these in Internet cafés, in your school,
and in most offices. This type of computer is
usually called a desktop personal computer.
Mobile Devices
A mobile device is a very small computer that
can fit in your pocket or that is small enough to
hold in your hand. There are many different
kinds of mobile devices out there.
LESSON 5: Say Hello to the Desktop
1.Identify the main parts

of a desktop
2.Explain the function of

each main part
The desktop computer is

the most common type
of computer. It is the one
we see in our school. We
use it for different
purposes.
Input, Process, Output
Parts of the Desktop

• Keyboard
• Mouse
• System Unit
• Monitor
SECTION 3 The Computer’s Companions
We have already learned the different

ways computers help us. In this section,
we will be introduced to the different
things that are attached to computers.
They help computers become more
useful. We will also learn how these things
are used.
LESSON 6: Little Machines on the Side
1.Differentiate peripheral
devices
2.Explain the uses of

peripheral devices
What are Peripheral Devices?
Computers become more useful with

the help of little machines that are
attached to them. These are called
peripheral devices.
Input and Output Devices
Printer Scanner
Input and Output Devices
Speakers Microphone CD/DVD

Drive
LESSON 7: Like a Shelf
1.Identify the different

storage devices
2.Explain why we use

storage devices
What is Storage?
A computer can remember information we input

with the help of a data storage device. A data
storage device is a peripheral device that can
keep information. Despite its small size, it can
keep a lot of data. You can think of it like a shelf.
You can put your things inside it, then take them
out again when you need them.
Examples of Data Storage Devices
Hard Disk Memory

Card
Flash Optical Discs

Drive
SECTION 4 Running the Computer Right
Like all other machines, computers must be
used correctly so that they will last. They
have to be taken care of. In this section, we
will learn how to correctly switch the
computer on and off. We will also learn some
healthful habits when using them.
LESSON 8: Computer On, Computer Off
1.Show the proper way

of switching a
computer on
2.Show the proper way

of switching a
computer off

Switching the Computer On
Our computers are usually connected to the
electric outlet by means of a device called an
automatic voltage regulator or AVR. Switch on
the AVR to bring power to your computer unit.
Turn your system unit on. The power switch is

usually located in front of the system unit. It is
often the largest button that you see.

Switch on the monitor so you can
watch your computer start.
After turning on your system unit and

your monitor, your monitor will show a
black screen with words and numbers
on it. This means that the system unit is
starting up.

A colored screen with little
images will then appear. We
call this screen the desktop.
The desktop can also have
pictures or drawings as its
background. We call this
background the wallpaper.

Switching the Computer Off
Using the mouse, bring the mouse pointer over the Start
button and click the left mouse button. A small menu will
appear. Bring the pointer over the Shut Down button and click
the left button again.
Switching the Computer Off
Finally, turn off the AVR.

LESSON 9: Habits that Help
1.Show healthful habits

when using a computer
2.Explain the importance

of having healthful
computer habits
Healthful Computer Habits

Stretch every twenty minutes. Sit up straight in your chair with
both feet on the floor.

Make sure your eyes are about You should not press the keyboard
two feet away from the screen. keys too hard.

Make sure your eyes are about two
feet away from the screen.
SECTION 5 Exploring the Keyboard
We will explore how to use the keyboard

in this section. The keyboard allows us to
input data, usually text, into the computer.
It is important for us to be familiar with the
keyboard so it will be easy for us to input
data quickly and correctly.
LESSON 10: What’s in the Keyboard
1.Describe the layout of

the keyboard
2.Identify the basic keys

to use when we input
text

The Keyboard
QWERTY layout
The easiest way to put information into your computer is by typing it
on the keyboard. It will help if you are familiar with the keyboard
layout. This refers to how the keys on the keyboard are arranged.

Basics of Text Input
Text input means pressing the correct keys on the keyboard to
write letters, numbers, and other symbols. Aside from
knowing the alphabet keys, you also have to know these keys:
Caps Lock Key

Enter Key
Shift Key
Backspace
Space Bar Key
LESSON 11: More Than Letters
1.Describe the layout of

the numeric keypad
2.Explain ways of
inputting numbers and
symbols
LESSON 11: More Than Letters
• Numbers and Symbols
• Input of Numbers
• Input of Symbols
LESSON 12: Keys in Action
1.Identify the keys used

for cursor movement
2.Identify other editing

keys
LESSON 12: Keys in Action
Movement Keys
• Arrow Keys
• Home Key
• End Key
Other Editing Keys
• Delete Key

SECTION 6 Matters of the Mouse
Another way to input data into the

computer is by using a mouse. There are
computer tasks that require the use of a
mouse. So it is very important to learn
how to use a mouse.
LESSON 13: What’s in a Mouse?
1.Identify the mouse and

its parts
2.State the different

types of mouse devices
LESSON 13: What’s in a Mouse?
