Quizplus · Accepted Answer

POST (Power-On Self Test) is the process of testing hardware components during the startup of a computer. One of the things it checks is the status of the CMOS battery. If the battery is dead or low, the startup BIOS will report the failure during POST. Firmware refers to software that's permanently programmed into a device, and OST (Open System Testing) is not a commonly used term in the context of computer hardware.
