The procedure is known as<u> context switching</u>.
In the field of computers, context switching can be described as a procedure in which a process is stored so that it can be executed at a later point. Such a procedure allows multitasking operations easier. A simple CPU can be utilized for multiple processes.
After a task is done, it can be swapped out of the CPU and can be restored later. By using context switching, more space can be provided on a CPU as freeing from one process will make space for the other.
When switching a process, the status of the older running process is saved on the CPU as registers.
Context switch makes it feasible to share one CPU for multiple procedures hence reducing the concerns that arise from using additional processors.
