On computer start-up, which program locates and loads the kernel into main memory for execution?

Correct option is A

The Bootstrap program is a small program stored in the ROM (Read-Only Memory) of a computer. It is responsible for initializing the hardware and loading the operating system kernel into the main memory during the start-up process. This process is also known as bootstrapping.
Important Key Points:
1. The Bootstrap program is executed automatically when the computer is powered on or restarted.
2. It performs a series of steps called POST (Power-On Self-Test) to ensure hardware functionality.
3. Once the kernel is loaded into memory, the operating system takes over control of the system.
Knowledge Booster:
· Start-up program: A generic term, not specifically tied to kernel loading.
· Boot-first program: Not a valid term in operating system terminology.
· Bootup program: Incorrect phrasing for the Bootstrap program.
· The Bootstrap program is essential for enabling the computer to transition from hardware initialization to OS execution.
