What is the initial hardware check performed by firmware when a computer starts called?

Answer and explanation

Correct answer: Power-On Self-Test

The governing concept is the startup or boot process. Power-On Self-Test, commonly called POST, is performed by firmware immediately after power is switched on to check essential components such as memory and basic input-output hardware. Thus, option A is correct. Disk defragmentation reorganises stored files, compression reduces file size, and system restore returns software settings; none is the initial hardware check.
