Answer / al hinai
A context switch is the computing process of saving and
restoring the state (context) of a CPU such that multiple
processes can share a single CPU resource. The context
switch is an essential feature of a multitasking operating
system.
Context switches are usually time consuming and much of the
design of operating systems is to minimize the time of
context switches.

protection boundary.

Answer / ragheed
When CPU switches to another process, the system must save the state of the old process and load the saved state for the new process via a context switch.
Context of a process represented in the PCB
Context-switch time is overhead; the system does no useful work while switching The more complex the OS and the PCB -> longer the context switch
Time dependent on hardware support Some hardware provides multiple sets of registers per CPU -> multiple contexts loaded at once
