Question

Which one is faster, Cache memory or RAM?

• A. RAM
• B. Both are of same speed
• C. Cache memory
• D. None

Answer 1

Answer:

C. Cache memory

• Cache memory and RAM ( Random Access Memory ) are both types of memory , but they serve different purposes and have different access speeds.
• Cache memory is a small , fast memory that stores frequently - used data or instructions. It's like a " quick access" storage for the CPU ( Central Processing Unit ). Access times for cache memory are typically in the range of 1-10 nanoseconds ( ns ).
• RAM, on the other hand, is the main system memory where data and applications are loaded. It's larger than cache memory but slower. Access times for RAM are typically in the range of 60-100 nanoseconds ( ns ).
