Q

What function does the POST perform in a computer?

A

Figures out what hardware is on the computer and makes sure it is running properly

The POST (Power On Self Test) figures out what hardware is on the computer and makes sure it is running properly before the BIOS initializes the hardware or loads up essential drivers.
