What is virtual memory in operating system?
Understand the Problem
The question is asking for an explanation of the concept of virtual memory within operating systems. Virtual memory is a memory management capability that allows the execution of processes that may not completely fit into physical memory by using disk space to extend the apparent available memory.
Answer
Virtual memory compensates for RAM shortages by using disk storage.
Virtual memory is a technique used by an operating system to use both hardware and software to compensate for physical memory shortages by temporarily transferring data between RAM and disk storage.
Answer for screen readers
Virtual memory is a technique used by an operating system to use both hardware and software to compensate for physical memory shortages by temporarily transferring data between RAM and disk storage.
More Information
Virtual memory allows a system to run larger applications or handle more processes simultaneously by treating secondary storage as an extension of RAM.
Tips
Confusing virtual memory with physical memory (RAM) is a common mistake. Remember, virtual memory uses disk space to extend RAM capabilities.
