Operating system
Computer
Load

In order to start working on a microcomputer called a desktop, you need to start it up or turn
it on. The process of turning on a computer is known as the booting process. This will allow
the computer to automatically load the operating system until the first screen appears.

How to turn on/switch on a desktop computer


If you are using a desktop computer, you will

symbol (shown besides).

Once turned on, your computer takes time before


it is ready to use. You may see a few different
displays flash on the screen. This process is
called booting up, and it can take anywhere
from 15 seconds to several minutes. Once the
computer has booted up, it may be ready to
use, or it may require you to log in.

10
The keyboard and mouse
You interact with a computer mainly by using
the keyboard and mouse, or a trackpad on
laptops.

The mouse controls the pointer on the screen.


Whenever you move the mouse across
the desk, the pointer will move in a similar
manner. A mouse usually has two buttons,
which are referred to as the left button and
the right button. You will often interact with
the computer by moving the mouse pointer
over something on the computer screen,
then clicking one of the buttons.

The keyboard allows you to type letters,


numbers, and words into the computer.
Whenever you see a flashing vertical line
called the cursor you can start typing.

Learners are put into groups of five. Groups are given numbers for identification. For
example Group 1, Group 2 and so on. One learner is the message giver. The group members
stand in a single file a metre apart. The message giver calls the group leaders and gives
them a message of choice. The group leader then goes and whispers the message to
the group member at the front. The group members pass the message in whispers. The
whisper should not be heard by any other person except the two members. They pass the
message to the last member. The last members of the group write the message down and
give it to the message giver. If the message is correct the group remains in the game, if
not they are out. The message giver continues giving messages until one group is left, the
remaining group is the winner.
