Explanation:
In computer science, a cache is a component that transparently stores data so that future requests
for that data can be served faster. The data that is stored within a cache might be values that have
been computed earlier or duplicates of original values that are stored elsewhere. If requested data
is contained in the cache (cache hit), this request can be served by simply reading the cache,
which is comparatively faster.
