Both CPUs and GPUs employ transistors, thus it's not apparent why cache memory is necessary. Volatile memory, or RAM (Random Access Memory), is already widely accessible. What are your thoughts on whether or not a computer needs many types of memory to do tasks?

I'm interested in the benefits of virtual Memory.

It is not apparent why cache memory is necessary since random access memory (RAM) is already there as a volatile memory and may be used instead. Is it feasible to utilize just one kind of computer memory for everything?

It is unclear why cache memory is necessary since RAM (Random Access Memory) is already accessible as a volatile storage device because cache memory and random access memory (RAM) are both transistor-based. Is it possible for a computer to do all of its tasks with only one kind of memory?

We may broadly divide computer memory into two types, as follows:

How does cache memory improve the efficiency of a computer's data processing?
