Is this sentence correct?
If there is no clock, no pulse will be there, if there is no pulse there will be no instruction, if there is no instruction perform then there will be no function and if no function perform there will be no program.
Not really. If there is no clock, the processor will just sit at the very first instruction (which is located at the reset vector) and do nothing, forever waiting to be told to do the next thing (whatever it may be).
