Rather than reading a single word or byte from main memory at
a time, each cache entry is usually holds a certain number of
words, known as a "cache line" or "cache block" and a whole

then nearby locations (particularly following locations) are
likely to be read soon afterward. It can also take advantage
consecutive locations.
