definition:
PCB (Process Control Block): The data structure that uses process management and control information in the system is called process control blocks.
The role of PCB:
The process control block is used to save relevant information about each process and resources, including process identification, space, operating status, resources and other related information. In order to control and manage processes and resources in operating systems. Therefore, its role is to make a program (including data) that cannot run independently in a multi -program environment, called a basic unit that can run independently, a process that can be executed concurrently with other processes.
PCB is the sole sign of the process:
In the entire life cycle of the process, the system always controls the process through its PCB. The system is perceived according to the PCB of the process instead of anything else, so the PCB is the only sign of the process.
