The correct answer is (a) POST.
POST stands for Power-On Self Test. It is a self-diagnostic test that is performed by the computer’s BIOS (Basic Input/Output System) when the computer is turned on. The purpose of POST is to verify that the computer’s hardware is functioning properly before loading the operating system.
If POST detects any errors, it will usually display an error code on the screen. The error code can be used to identify the specific hardware component that is causing the problem.
If POST does not detect any errors, it will load the operating system from the hard drive. The operating system then takes over control of the computer and allows the user to start working.
The other options are incorrect.
(b) GHOST is a software program that can be used to create images of a computer’s hard drive. These images can then be used to restore the computer to its original state or to transfer the image to another computer.
(c) HOST is a networking term that refers to a computer that is connected to a network and that provides services to other computers on the network.
(d) HOTS is a term that is used in the field of education to refer to higher-order thinking skills. These skills include critical thinking, problem solving, and creativity.
