Best Answer

Context switching is how the computer's operating system multitasks different processes. It lets one process run for a while and then saves a copy of the process' run state (such as register values) off to the side, restores the run state of the next process back into the processor, and runs it for a while. Context switching is this process of swapping one program out of the CPU and replacing it with another process.

What is the difference between context switching and mode switching?

Context means ,in terms of computers, the status of various general purpose registers having some process specific data values and even some other structures dependent on computer hardware,i.e. PCB etc. Now what context switch means ,""switching from one status of registers set to another status of registers set."" This context may be of a process or thread etc. Now when we are talking about any type of context switching,,it means we are requesting the KERNEL to save the current context anywhere,and fetch the next context for us.. It requires a mode switch between user mode to kernel mode, so that required switching may be performed in right order.... Isn't it simple ,,or what.
