1. Operating System
Assignment
DONE BY M. ABISHEK

2. Process control
block(PCB)
Process control block is data structure used by
os to store all the information about process.
It is also called task control block

3. Block
Diagram of
the PCB

4. Process state
It contains the information about the state of
the process.
 running
 Waiting
 New
 Ready

5. Process id

6. Program counter
 The counter specifies the address of the next
instruction to be executed.
CPU registers
 Register means small amount of fast memory.
 CPU use registers for storage during execution.

7. CPU scheduling information
it deals on :
 process priority.
 pointer to scheduling queues.
Memory-management information
 Allocated memory to process by os will be stored .

8. Accounting information
 Time used by the process in CPU.
 Clock time pass since start.
 Time limits.
I/O status information
 list of I/O devices allocated to process process
 list of open files
