Since the operating system has effectively suspended the execution of the first process, it can now load the PCB and context of the second process. In doing so, the program counter from the PCB is loaded, and thus execution can continue in the new process. New processes are chosen from a ...
1.1 what is Context switching This single-file line could be quite inefficent and there are times when you want a computer to be processing many different things at once, rather than one thing at a time. For example, most computers rely on peripherals for input, but those peripherals are o...
the computer must first save the current state of the CPU in memory before switching to the new program.Later, when switching back to the original, the computer must load the state of the CPU from memory
context switching造句 1、Thread context switching is NOT expensive.线程上下文切换的代价并不大。 2、The CPU simply becomes overburdened by context switching between threads.由于要在线程间进行上下文切换,因此CPU简直变成了超载。 3、Context switching in a complex task environment like software development is...

Context switching can be described in slightly more detail as thekernel(i.e., the core of theoperating system) performing the following activities with regard to processes (including threads) on the CPU: (1) suspending the progression of one process and storing the CPU'sstate(i.e., the con...
