Implementation of processes

In modern multitasking systems, the Process Control Block (PCB) stores many different items of data, all needed for correct and efficient process management. PCB is the data structure that resides in the operating system kernel which contains the information needed to manage the process. The PCB is the representation of the process in the operating system. Though the details of these structures are system-dependent, there are some very common parts, which could be classified into three main categories:

  • Process identification data
  • Processor state data
  • Process control data
    Implementation of processes

The role of the PCB is central in process management. ...
