WHAT IS MEMORY CACHING?

Question

can somebody sum up what that is? It is dealing with computers

Answer 1

Memory caching is when the computer attempts to predict what files will be called on next, and loads them into memory so they are already set to go.

Answer 2

In computer science, a cache (pronounced /kæʃ/ or /kaʃ/[citation needed]) is a collection of data duplicating original values stored elsewhere or computed earlier, where the original data is expensive (usually in terms of access time) to fetch or compute relative to reading the cache. Once the data is stored in the cache, future use can be made by accessing the cached copy rather than re-fetching or recomputing the original data, so that the average access time is lower.

Caches have proven extremely effective in many areas of computing because access patterns in typical computer applications have locality of reference. There are several kinds of locality, but this article primarily deals with data that are accessed close together in time. The data might or might not be located physically close to each other.
