Monitor

 A monitor is the visual
component of your
computer; it is how you
interact with your
computer by seeing a
visual representation of
what you are doing.

4

Tower

 The tower is where all the
processing goes on in a
computer; it is the brains
of the computer.
 The tower is connected
via a cord to the monitor
so you can see what the
tower is doing on the
monitor.

5

Keyboard

 The keyboard is also connected to the tower
and it is used primarily to enter information
into the computer.
 This information entering is done by typing.

6

Mouse

 The mouse is the primary tool used to
navigate the user interface that is displayed
on the monitor.

7

VGA

 VGA stands for Video Graphics Array. A VGA
connector is very important, as it is used to
connect the computer tower to the monitor.
 The VGA connector allows the monitor to
display a graphical representation of what is
going on in the computer.

8

VGA cont.

 This is a standard VGA cable. One side plugs
in to the monitor, the other side will connect
to the computer tower.

9

Ethernet

 An ethernet cable is used to physically
connect the computer to the internet.
 The internet is worldwide and it is a system of
interconnected computer networks.
 Using these networks, people are able to
share information worldwide, and an ethernet
cable allows you to connect your computer
into this worldwide network.

10

Wireless

 Another option to connect to the internet is
through a wireless card.
 Many newer computers have a built in
wireless card, meaning they can detect
nearby routers and you can connect to these
routers if you have the proper permissions/
passwords to join them.
 A router is a device that can send out a
wireless internet computer to many
computers, allowing them to access the
internet.
11

USB

 USB (Universal Serial Bus) is universal
connector to enable many different devices to
connect to your computer.
 In the past, there were different connectors
for almost everything to connect to your
computer (mouse, keyboard, printer, etc.),
and many of these are being replaced with
USB connectors.

12

USB cont.
 This is a standard
USB cable. The end
that connects to your
computer tower will
always be the same
size.
 The size of the
connector on the
other side may differ
depending on the
device you are
connecting to.
13

Laptops
 Laptops are very
similar to tower
computers except
the monitor,
processing
components,
mouse, and
keyboard are all
one unit on a
laptop instead of
being separate.

16

How to Power On
 You turn on the computer by pushing the
power button, which is usually located on the
front of the tower.
 You briefly push the button and then let go –
you don’t want to hold down on the power
button.
 The computer will then take a few minutes to
power up and be ready to use.

17

How to Move a Mouse

 There is a pointer icon on the screen that you
move by physically moving the mouse.
 By clicking the buttons on the mouse, you can
interact with various programs on the
computer.
 You will physically move the mouse whatever
direction you want the pointer to move on the
screen – move it up to move the mouse up,
left to move it left, etc.

18

Logging On

 When you first turn the computer on, you will usually
see a log on screen after the computer has finished
powering on.
 There will be a menu showing an icon and name for
each user that has an account on the computer.
 Some of these accounts may be password protected
and so you will need to know the proper password to
access these accounts.
 You will select the correct name for your account,
enter the password if one is required, and then you
will be logged in to the computer.

19

Introduction to Keyboards

 Keyboards are the main tool available to enter
text into the computer.
 If you wanted to type a letter, you would open
a word processing program, such as wordpad,
notepad, or Microsoft Word.
 Using wordpad, you can type your letter just
as you would write it on paper. However,
instead of using pen and paper, you will press
on the letters on the keyboard that
correspond to the letters you wish to type.
