____________________ wakes up the computer
- A.
RAM
- B.
ROM
- C.
CPU
- D.
BIOS
Correct Answer
D. BIOSExplanation
The BIOS (Basic Input/Output System) is responsible for waking up the computer. It is a firmware that is stored on a ROM (Read-Only Memory) chip on the motherboard. When the computer is turned on, the BIOS initializes and performs a power-on self-test (POST) to check the hardware components. It then loads the operating system from the storage devices into the RAM (Random Access Memory) for the computer to boot up. Therefore, the BIOS is the correct answer as it is responsible for the initial startup process of the computer.Rate this question:
