Explanation:
Kernel is the program that is used as the first software program to connect with the hardware devices of the system. Rudimentary functions provides limited functions when the Kernel is designed with it to provide primary services to the system.
The major services required for such design are as follows :-
- Presence primary interrupt function
- Requires RAM for the memory space
- Primary services scheduling
- Citing the kernel using Bootstrap program
E.g.- By turning-on the computer system, the first program to get already loaded from disk to memory space is the Bootstrap program .Then the device is ready and can be used for calling the external program.
