The correct answer is: B. Power on Self Test (POST)
The Power-On Self Test (POST) is a process that is performed by the computer’s BIOS (Basic Input/Output System) when the computer is turned on. The POST checks the hardware components of the computer to make sure that they are working properly. If any problems are detected, the POST will generate an error code that can be used to troubleshoot the problem.
The POST is a very important process because it ensures that the computer’s hardware is working properly before the operating system is loaded. If the POST fails, the computer will not boot up and an error message will be displayed.
The POST typically takes a few seconds to complete. During the POST, the computer’s BIOS will perform a series of tests on the following components:
- CPU
- RAM
- ROM
- Video card
- Keyboard
- Mouse
- Hard drive
- Optical drive
If any of these components are not working properly, the POST will generate an error code. The error code can be used to troubleshoot the problem.
The POST is a very important process that ensures that the computer’s hardware is working properly before the operating system is loaded. If the POST fails, the computer will not boot up and an error message will be displayed.
The following are the other options and their explanations:
- A. Start-up utility test: This is a test that is performed by the computer’s operating system to make sure that the operating system is working properly. The start-up utility test is not as comprehensive as the POST and it does not check all of the computer’s hardware components.
- C. Power up boot process: This is the process that is used to load the operating system into the computer’s memory. The power up boot process is not as comprehensive as the POST and it does not check all of the computer’s hardware components.
- D. Power on start up process: This is the process that is used to turn on the computer. The power on start up process is not as comprehensive as the POST and it does not check all of the computer’s hardware components.
- E. None of the above: This is not an option.
