Which type of Memory is typically the fastest in a computer system?

Cache memory is the fastest type of memory in a computer system, located close to the CPU. It stores frequently accessed data and instructions to speed up processing. Cache memory plays a critical role in improving overall system performance by reducing access time. a) Hard Disk is a form of secondary storage, much slower than cache. b) RAM is faster than secondary storage but slower than cache. d) ROM is read-only memory, slower than cache and mainly used for storing firmware. e) Virtual Memory is a section of the hard drive used to simulate additional RAM, and it is the slowest form of memory.
