What are the differences between RAM and virtual memory?

What are the differences between RAM and virtual memory?

RAM (Random Access Memory) is a type of volatile memory that stores data temporarily for quick access by the CPU, while virtual memory is a memory management capability that uses disk space to extend the apparent amount of RAM available.

Why is RAM faster than virtual memory?

RAM is faster because it is directly connected to the CPU, allowing for quicker data retrieval, whereas virtual memory relies on slower disk storage.

Can virtual memory replace RAM?

No, virtual memory cannot replace RAM. It supplements RAM by providing additional space, but it is significantly slower and not a substitute for the speed and performance of actual RAM.

How does the operating system manage virtual memory?

The operating system manages virtual memory by using a paging system that swaps data between RAM and disk storage, ensuring that active processes have the memory they need.

What happens if I run out of both RAM and virtual memory?

If you run out of both RAM and virtual memory, your system may slow down significantly or crash, as it won't have enough memory to run applications.
