Chapter 7 - Turning ON / OFF the Computer

One thing a computer definitely needs to work is electricity. A desktop computer
must always be connected to a power outlet, while a laptop may operate on its
own internal battery for a few hours. In any case, without power the computer is
pretty useless.

The Power Button (s)

A desktop computer has two power buttons. One is on the Monitor for turning on
the monitor and the other is on the front of the System Unit for turning on the
system unit. The laptop, because its system unit and monitor are built in one
unit, has only one power button which is mostly at the top right corner of the
Keyboard.

Booting

Booting is the process of pushing and releasing the power button of the

computer to load the very first software that starts and control the computer. In
other words, booting is a process of turning on the computer. Alternatively, it is
referred to as boot up.

Types of booting
Cold Booting
Warm Booting

Cold Booting
Cold booting is the process of switching on the computer from the main switch.
It involves the pressing of the power buttons on the system unit and the monitor
to on the computer.
