Context Switching in Operating System

Context Switch in OS

Context Switching is a cost and time saving measure performed by the CPU that is handing task 1 and has to stop executing this task to priority execute another task 2. To do this effectively, the system stores the initial task in its processed form so that when this task is resumed, it can be loaded and resumed from the same progress point as earlier.

This allows the computer to multitask and multiple processes can share the same CPU. This is also done to make sure that tasks do conflict one another, as they may be holding a same resource for execution like memory etc.
