Each process in an operating system is represented by a process control block (PCB). The PCB is a data structure that contains information needed to manage a particular process, including a pointer, the process state (such as new, ready, running, waiting, halted), and the program counter which specifies the address of the next instruction to be executed. The presentation discussed the components and purpose of a process control block.

2. What is process control block
 Each & every process in the operating system is represented by PROCESS
CONTROL BLOCK.
 Process Control Block also known as Task Controlling Block or Process
Table.

3. PROCESS CONTROL BLOCK
 Its is a data structure in the operating system kernel containing
the information needed to manage a particular process.
 The PCB is "the manifestation(visible) of a process in an
operating system"4

5. PROCESS CONTROL BLOCK (PCB)
 PCB consist of following information~
 Pointer.
 Process state.
 Program counter.

6. PROCESS CONTROL BLOCK (PCB)
 POINTER
 Its contains the address of another process which is present in the
ready queue

7. PROCESS CONTROL BLOCK (PCB)
 PROCESS STATE
 Its contains the information about the state of the process i.e.,
 NEW
 READY
 RUNNING
 WAITING
 HALTED

8. PROCESS CONTROL BLOCK (PCB)
 Program COUNTER
 The counter specifies the address of the next instruction
to be executed.
