What is Virtual Memory

1. Virtual Memory is a capacity assignment conspire in which auxiliary memory can be tended to as in spite of the fact that it were portion of the fundamental memory.
2. A virtual memory is what its title demonstrates- it is an figment of a memory that is bigger than the genuine memory. We allude to the program component of virtual memory as a virtual memory chief. The premise of virtual memory is the noncontiguous memory allotment demonstrate.
3. The virtual memory director expels a few components from memory to make room for other components.

Types of Virtual Memory

• Paging

Paging separates memory into little fixed-size squares called pages. When the computer runs out of Smash, pages that aren't right now in utilize are moved to the difficult drive, into an region called a swap record. The swap record acts as an expansion of Smash. When a page is required once more, it is swapped back into Slam, a prepare known as page swapping. This guarantees that the working framework (OS) and applications have sufficient memory to run.

• Segmentation

Segmentation partitions virtual memory into portions of diverse sizes. Portions that aren't as of now required can be moved to the difficult drive. The framework employments a portion table to keep track of each segment's status, counting whether it's in memory, if it's been adjusted, and its physical address. Sections are mapped into a process's address space as it were when needed.
