Booting is a process that starts operating system when the user turns on the computer.
Steps in booting a Computer:
- Put on the switch on the main socket to supply power to the system.
- Switch on the voltage regulator( known as stabilizer)
- Switch on the UPS
- Switch on the monitor before the system unit
- Wait for system check until you see start up icon, if you are using window Operating system.
It is advisable to watch out for any unusual message that might be displayed on the screen during this period and respond appropriately.
The computer tests its entire hardware component to ensure that they are in working condition. The test is known as power on self-test (POST).
If booting is successful, the operating system is loaded from the disk into RAM. The screen shows icons such as the computer, recycling bin, internet explorer. At this point computer is ready for use.
TYPES OF BOOTING
We have two types of booting: warm booting and cold booting
Warming Booting: means re-starting the computer after it has been switched on and it is still currently working. This take place when any of the following problems occur.
- Changing of the computer during system checks
- Stopping of the booting process due to some hardware failure
- Sudden power failure resulting in the abortion of a running program
- Failure of some programs to execute
Cold booting: when computer is switched on from the scratch following the the above procedure of powering up a computer.
Difference between Cold Booting and Warm Booting
|COLD BOOTING||WARM BOOTING|
|THE SYSTEM IS TURNED ON FROM THE SCRATCH||THE SYSTEM IS ALREADY ON|
|COLD BOOTING IS SLOWER||WARM BOOTING IS FASTER|
|SYSTEM CHECKS TAKES PLACE AND YOU SEE WINDOWS DESKTOP AFTER BOOTING||CONMPUTER SKIPES SOME STAGES OF THE SYTEM BOOT PROCESSES|
