What is the first job the Basic Input Output System(BIOS) does at start-up?
-
Run memory byte count
-
Test for parity errors
-
Load instructions to RAM
-
Run the power-on-self-test
Correct Answer
A. Run the power-on-self-testExplanation
At start-up, the BIOS performs a power-on-self-test (POST) to check the hardware components of the computer. This test ensures that the essential hardware components are functioning properly before the operating system is loaded. It checks the CPU, memory, storage devices, and other peripherals for any errors or faults. By running the POST, the BIOS can identify any potential issues and provide error codes or messages if necessary. Therefore, the first job of the BIOS at start-up is to run the power-on-self-test.Rate this question:
