D)POST

Question

Quizplus · Accepted Answer

CMOS (Complementary Metal Oxide Semiconductor) is a type of semiconductor that uses low power, making it ideal for portable devices. It also has a non-volatile memory that retains its contents even when power is removed, making it the best choice for a portable computer system with memory that can be updated but does not lose its contents when turned off. ROM (Read Only Memory) is a type of memory that is non-volatile but cannot be updated, while RAM (Random Access Memory) is volatile and loses its contents when power is removed. POST (Power-On Self-Test) is a diagnostic program that checks the computer hardware during boot-up and is not related to memory retention.
