Explain the concept of virtual memory.

• Virtual memory does not create an illusion of a large memory

• Virtual memory is a type of physical memory

• Virtual memory is a memory management technique that provides an idealized abstraction of the storage resources that are actually available on a given machine, which creates the illusion to users of a very large (main) memory.

• Virtual memory is only used in small computers
