From what location are the 1st computer instructions available on boot up?
Answer & Solution
Correct Answer:
Option
A
During boot-up, the first computer instructions are typically fetched from the ROM BIOS (Read-Only Memory Basic Input/Output System).
ROM BIOS contains firmware that initializes hardware components and performs the initial loading of the operating system.
It is a crucial component of the boot process, responsible for tasks such as POST (Power-On Self Test), hardware initialization, and loading the bootloader.
The BIOS resides on a ROM chip on the motherboard and is essential for the computer to start up properly.
Therefore, the first set of instructions during boot-up comes from the ROM BIOS.
