Question

When an operating system is loaded into the memory the dash is loaded first and remains in the memory until the computer is shut down

Answer 1

Answer:

1.When the computer is first turned on, the main memory does not contain any valid bits. The operating system itself must be loaded from the hard drive to the main memory. This seems like a catch-22! The solution is a progressive sequence of larger and larger booting programs that load the OS.

2.When the computer is turned on or restarted, it first performs the power-on-self-test, also known as POST. If the POST is successful and no issues are found, the bootstrap loader will load the operating system for the computer into memory.

3.In most modern computers, when the computer activates the hard disk drive, it finds the first piece of the operating system: the bootstrap loader. The bootstrap loader is a small program that has a single function: It loads the operating system into memory and allows it to begin operation.

Answer 2

Answer:

To be more precise, it's the Kernel.

Explanation:

The kernel is an essential part of an operating system and acts as an interface between applications and the hardware.

When the operating system is loaded into memory, the kernel is loaded first in the memory until the computer is shut down.
