Question

Difference between w main memory and cache memory

Answer 1

Cache memory is a high speed memory that is used to store frequently accessed data. Whenever it is required, this data is made available to the Central processing unit at a rapid rate.  Main memory is also known as Random Access Memory. It is a memory unit that directly interacts with the central processing unit (CPU).

Main memory is also known as Random Access Memory (RAM). It is a memory unit that directly interacts with the central processing unit (CPU). It is a volatile source of data. It can be described as a large array comprising of words or bytes. RAM is connected with the processor by its address and data buses. These buses are composed of electrical circuits or bits. Main memory is actually built from DRAM chips or Dynamic RAM.
