Why utilize cache memory based on transistors if RAM is volatile? Can a computer employ just one form of memory?

Since both cache and RAM use transistors as their primary building block, it's natural to question why we need two types of volatile memory. This is due to the fact that both cache memory and random access memory are dependent on transistors. Does the computer need many kinds of memory, or can a single type be utilised for everything?

What is the purpose of having cache memory if we already have RAM, which is a memory that is built on transistors and may quickly get corrupted?Is it feasible to operate a computer with only a single kind of memory installed at a time?

In light of the fact that transistor-based RAM and cache memory both exist, it's not apparent what the purpose of cache memory is. Does it occur to you that a computer may run on just one kind of memory?
