Operating Systems · Question 5 · Easy
Where does the operating system save a process's program counter, CPU registers and state during a context switch?
- Page table
- Translation Lookaside Buffer (TLB)
- Process Control Block (PCB)
- Interrupt vector table
Answer and explanation
Answer: C. Process Control Block (PCB)
Explanation: Each process has a PCB, which stores its state, program counter, registers, scheduling and memory-management information. These values are saved there and restored on a context switch.
