Hi Mike, this is the continuation of the OS post to look briefly about the virtual memory and demand paging.

Virtual Memory:

When a process is processed by the processor, it will reside in the main memory. When the process is bigger in space than the main memory, then a part of secondary memory is also used as the main memory. This memory is called virtual memory.

Demand Paging:

Demand paging is similar to paging concepts. Some of the virtual memory basics also come in it. The process which is huge enough and not fitting in the main memory will not reside in main memory. The pages of the process being processed will be alone in the main memory. The pager will swap the pages demanded by the processor. This is demand paging.

So Mike, i hope, i cleared the concepts. We are having a technical get together soon and i will intimate you about that. You can join us
