Question

If there are 'n' processor and 'm' processes then maximum process in block state can be?

 

I think its m-n but answer is 'm' how?

Answer 1

• If a running process require i/o operation then it will moves into the block state .

• In wait state also multiple process will performe i/o operation.

• In worst case If all process require i/o operation then all will can go in block state . 

• So there are m process . And all require i/o then all will go into the block state . Which is maximum.
