(a)i) What is booting?
(i) State two differences between the types of booting.
(b) What is peripheral?
(c) Give one example each of (i) input device; (ii) output device; (iii) storage devices (iv) a component found inside the system unit.
Answer Details
(a)(i) What is booting?
Booting is the process of starting up a computer, during which the operating system is loaded from secondary storage into main memory (RAM) so that the computer becomes ready for use. It begins when power is switched on and the system runs its start-up instructions.
(a)(ii) Two differences between the types of booting (cold vs warm booting):
| Cold booting | Warm booting |
|---|---|
| Starting the computer from a completely switched-off state (power on). | Restarting a computer that is already on, without switching off the power. |
| Full Power-On Self-Test (POST) is carried out. | POST is usually skipped or reduced. |
| Done using the power button. | Done using the Restart command or Ctrl+Alt+Del. |
(Any two differences are acceptable.)
(b) What is a peripheral?
A peripheral is any device that is connected to and works with the computer but is not part of the central processing unit. Peripherals are used to put data into the computer, get results out, or store data (for example keyboard, printer, monitor and external disk).
(c) One example each:
- (i) Input device: keyboard (also mouse, scanner).
- (ii) Output device: monitor (also printer, speaker).
- (iii) Storage device: flash drive (also hard disk, CD/DVD).
- (iv) A component found inside the system unit: the motherboard (also CPU, RAM, power supply).
