Computer Memory is designed in layers to balance speed, cost, and capacity.
Cache Memory is a small, super-fast, and expensive type of memory that stores the most-used data to help the CPU work faster.
On the other hand, Main Memory (RAM) is larger, slower, and cheaper, used to store programs and data while your system runs.
In short:
👉 Cache = Small + Fast + Costly
👉 Main Memory = Large + Slower + Cheaper
A perfect example of how computers maintain both speed and efficiency — just like how aspirants use quick notes (cache) and full books (main memory) in preparation!
