If process P0 is switched to process P1, state for P0 will be saved into , and state from ___ will be reloaded.

1. PCB0

2. PCB1

Explanation:

Given that PCB is often referred to as Process Control Block, is a form of data structure that is applicable and utilized by the computer operating systems to store all the information concerning a process.

This process is carried out in a way that when Process P0 is initialized, the operating system established a related process that takes the computer processing unit from Process P0 and allocates it to Process P1, the Operating System, in turn, will save P0's PCB, and then reload P1's PCB.

Hence, If process P0 is switched to process P1, the state for P0 will be saved into "PCB0" and the state from "PCB1" will be reloaded.
