Detailed explanation-1: -A power-on self-test (POST) is a process performed by firmware or software routines immediately after a computer or another digital electronic device is powered on. It is the initial set of diagnostic tests performed by the computer right after it’s powered on, with the intent to check for any hardware related issues.
Detailed explanation-2: -The power-on self-test (POST) keys can start services or can initiate service mode boots that are used for configuring the system and diagnosing problems. After power is turned on and before the operating system is loaded, the system performs a power-on self-test (POST).
Detailed explanation-3: -The POST (power on self-test) is a set of procedures that a computer runs through each time it is turned on. It ensures that all of the system’s hardware is working properly before trying to load the operating system. If the computer does not pass POST, it will not boot.
Detailed explanation-4: -Power-on self-test (POST) performs tests on workstation core components such as CPU and memory. POST checks low-level interaction between the CPU, caches, memory, JBus, and the I/O bridge chip. Typing the post command from the ok prompt initiates tests that check the CPU, I/O bridge chip, and memory modules.
