In this post, we will understand the difference between virtual memory and cache memory in operating system −

Cache Memory

• It helps improve the access speed of CPU.

• It is a memory unit that improves access speed.

• CPU and other related hardware helps manage the cache memory.

• This is small in size.

• It is used to store the most recently used data.

Virtual Memory

• It increases the capacity of the main memory.

• It is a method that involves the hard disk.

• It is a slow process.

• It is managed by the virtual memory.

• The size of virtual memory is larger than that of cache memory.

• Virtual memory stores the programs that can’t be stored in the main memory.
