What is the swapping and explain of benefits of swapping(OS-7)

-

swapping

-A process can be swapped temporary out of memory to a backing store and then brought back into memory for continued execution.
-Switching a process from the main memory to backing store is called swap out and switching a process from disk to the main memory is called swap in.
-The swap out and swap in to process is called as swapping.
-swapping is increase the context of switch.

  Benefits of swapping:

-It offer a higher degree of multi programming.
-It allows a dynamic relocation.
-It is help to get better utilization of the main memory.

What is demand paging(OS-9)

-
Image
Demand paging -Loading the entire program in the physical memory at program execution time is not so good because the user does not need the entire program in memory at a time. -An alternative strategy is to load pages only as they are need this technique is known as demand paging. -With demand paging virtual memory, pages are only loaded when they are demanded during program execution pages that are never accessed thus never loaded into physical memory.    -A demand paging system is a similar to paging system with swapping, -But here it uses a lazy swap where it never swap a pages into memory unless that page will be need. -In demand paging pager is more suitable than swap er.

Draw process state diagram and explain each state(OS-3)

-Process state means current activity of process. -When process is execute it changes the state generally state of process is determine by the current activity of process. -Each process may be in one of the following state. new- the process is being is oriented. ready- the process is waiting to be assigned to the processor. waiting - the process is waiting for some event (I/O operation) to occur. running - the process is being executed.  terminated -the process as finished the execution. process state diagram: -The pictorial is represented to the process changing from one process to another process during       there  execution is known as process state diagram. -A process can be change for one process in the following manner. new ready: The operating system(os) create a process and prepares the process to be executed ,then the os moved the process into the ready queue.  ready running: When it is time to select a process to run, the os selects one jo
