A process in an operating system is represented by a data
structure known as a process control block (PCB) or process
descriptor. The PCB contains important information about the
specific process including
* The current state of the process i.e., whether it is
ready, running, waiting, or whatever.
* Unique identification of the process in order to track
"which is which" information.
* A pointer to parent process.
* Similarly, a pointer to child process (if it exists).
* The priority of process (a part of CPU scheduling
information).
* Pointers to locate memory of processes.
* A register save area.
* The processor it is running on.
The PCB is a certain store that allows the operating systems
to locate key information about a process. Thus, the PCB is
the data structure that defines a process to the operating
systems.
