The actions taken by the kernal in the operating system for a contex.pdf
The actions taken by the kernal in the operating system for a context switch are as follows -> In response to a clock interrupt, the operating system saves the program counter and user stack pointer of the currently executing process , and transfers control to the kernel clock interrupt handler. -> The clock interrupt handler saves the rest of the registers, as well as other machine state, such as the state of the floating point registers, in the process PCB (process control block). -> The operating system invokes the scheduler to determine the next ptocess to execute. -> The operating system then retrieves the state of the next process from its PCB, and restores the registers. This restore operation takes the processor back to the state in which the this process was previously interrupted, executing in user code with user mode privileges.
