`Hey,

Note: If you have any queries related to the answer please do comment. I would be very happy to resolve all your queries.

Cache memory increases the accessing speed of CPU. It is not a technique but a memory unit i.e a storage device. In cache memory, recently used data is copied. Whenever the program is ready to be executed, it is fetched from main memory and then copied to the cache memory. But, if its copy is already present in the cache memory then the program is directly executed.

Virtual Memory increases the capacity of main memory. Virtual memory is not a storage unit, its a technique. In virtual memory, even such programs which have a larger size than the main memory are allowed to be executed.

Kindly revert for any queries

Thanks.
