Question 5

(i) What is booting?

(ii) State two differences between the types of booting.
(b) What is a peripheral?
(c) Give one example each of:
(i) input device;
(ii) output device;
(iii) storage device;
(iv) a component found inside the system unit.

Observation

     (a) (i) Booting is the process of turning / switching on the computer system using the start button in which the required software for the optimal performance of the system are allowed to load into memory.
OR
Booting is a startup sequence that starts the operating system of a computer when it is turned on using the start button.
                                                                        OR
Booting is the initial set of operations that computer perform when it is switched / tuned on using the start button.
            (ii)       Differences between the types of booting

COLD BOOTING	WARM BOOTING
CPU stops running	CPU continuous running
Power supply and motherboard resources stops working	Power supply and motherboard resources do not shut down
Memory and BIOS are reset	Memory and BIOS are not reset
Computer shut-down completely	Computer doe not shut-down completely
The computer system may not necessarily have program error before it is performed	Is necessary when a program encounters an error from which it cannot recover
Use of power-switch is involved	It involved short cut keys e.g (CTRL+ALT+DEL)
It is done when the system is already off	It is done when the system is on

A peripheral is an external/physical/hardware device that provides input or output for the computer. It can be felt or touched.
