What data structure is used by an operating system to keep track of process information? Explain

A data structure termed as process control block (PCB) is used by an operating system to keeps track of all information relating a process. The PCB of a process consists of the subsequent information.

Process ID

Priority

Process state

PSR

Registers

Event information

Memory allocation

Resources held

PCB pointer

(a) Process scheduling information: This information contains three fields process ID, process state, priority.

(b) PSR and machine registers: These fields have contents of the processor states register (PSR) and the machine registers while the execution of the process was final suspended.

(c) Event information: While a process is in blocked state, this field consists of information concerning the event for that the process is waiting.

(d) Memory and resource information: Such information is helpful for the de-allocating memory and resources while the process terminates.

(e) PCB pointer: This is a pointer to the next PCB in the process scheduling list.
