Kernel is central component of an operating system that manages operations of computer and hardware. It basically manages operations of memory and CPU time. It is core component of an operating system. Kernel acts as a bridge between applications and data processing performed at hardware level using inter-process communication and system calls.
What is the main goal of multiprogramming system? Main goal of using of multiprogramming system is overcome issue of under utilization of CPU and primary memory. Main objective of multiprogramming is to manage entire resources of the system. The primary components of multiprogramming system are command processor, file system, I/O control system

Multiprogramming In multiprogramming, multiple programs reside in main memory (RAM) at a time. OS which handles multiple programs at a time is known as a multiprogramming operating system. One processor or CPU can only run one process at a time. OS uses context switching in the main memory for running multiple programs.
A process control block (PCB) contains information about the process, i.e. registers, quantum, priority, etc. The process table is an array of PCBs, that means logically contains a PCB for all of the current processes in the system. Pointer: It is a stack pointer that is required to be saved when the process is switched from one state to
