Answer / ravi
I think,
In multitasking, One process run as much as it wants but when it wait(blocked) for slow IO operation it becomes blocked & turn is given to another process to run.
In time sharing, All process be given a time slot,for example 5 ms,at the end of time slot timer generate a pulse & task is switched.
