Understanding Cache Memory: The Librarian's Efficiency Secret

This is a submission for DEV Computer Science Challenge v24.06.12: One Byte Explainer.

Explainer

Cache memory is like a librarian's desk: it stores frequently accessed information for quick retrieval. It sits between main memory (bookshelves) and the CPU (reader). Faster than RAM but smaller, it optimizes performance by reducing the need to fetch data from slower memory.

Additional Context

Understanding cache hierarchy is crucial for optimizing system performance in CPUs. It minimizes latency and boosts efficiency by exploiting the principle of locality, where recently accessed data is likely to be accessed again soon.
