What Is Context Switching in Embedded System?
Context Switching involves storing the context or state of a process so that it can be reloaded when required and execution can be resumed from the same point as earlier. This is a feature of a multitasking operating system and allows a single CPU to be shared by multiple processes.

Herein, what is context switching in RTOS?

When the task is resumed its saved context is restored by the operating system kernel prior to its execution. The process of saving the context of a task being suspended and restoring the context of a task being resumed is called context switching.

Additionally, what is context of a process? Process context is its current state. We need to save the context of the current running process so it can be resumed after the interrupt is handled. Process context is basically its current state (what is in its registers).

Hereof, what is context switching Where does it occur what is context in which type of OS context switching is found as an essential feature?

Context switching is when the CPU switches from one process to another. It occurs in the central processing unit. The contents of a CPU's register and program counter is the context. Context switching is found as an essential feature in multitasking OS.

What is context switching in OS Geeksforgeeks?

The process of saving the context of one process and loading the context of another process is known as Context Switching. In simple terms, it is like loading and unloading the process from running state to ready state.

What do you mean by context switching?

A context switch is a procedure that a computer's CPU (central processing unit) follows to change from one task (or process) to another while ensuring that the tasks do not conflict. Effective context switching is critical if a computer is to provide user-friendly multitasking.

Why is context switch overhead?

Context-switch time is pure overhead, because the system does no useful work while switching. Context switching is overhead because it is cycles (time) that the processor is being used but no user code is executing, so no directly productive computing is getting done.
