Question

Q// Briefly describe how increasing the number of available process in main memory can increase the CPU utilization in a uniprocessor system ?? (short Answer)

Answer 1

As we know that uniprocessor system has only one Central Processing Unit(CPU) which is used for executing the tasks like adding, subtracting, multiplying the operands and many other tasks.
When we talk about CPU utilization then we think that ideally the the CPU utilization should be 100%, it means 0 wastage of CPU cycle .
But practically it is not possible and mainly CPU utilization varies from 40% to 90%.

So for increasing the CPU utilization the Job scheduler should keep CPU as busy as possible.
Job scheduler selects the process whichever is in ready state from Main memory and send it to CPU for performing desired tasks or operations.
Since different process are stored in main memory in different states like ready , running, waiting, blocked and terminated.

So if there are more and more processes are present in main memory in ready state then automatically the CPU utilization will get increased and CPU will always remain busy in executing those processses.

Please let me know if you need more explanation.
