Similarly one may ask, What is caching and how does it work? Caching is a process that stores multiple copies of data or files in a temporary storage location — or cache — so they can be accessed faster.

Simply so, What is a cache in Computer Science? In computing, a cache is a high-speed data storage layer which stores a subset of data, typically transient in nature, so that future requests for that data are served up faster than is possible by accessing the data’s primary storage location. Caching allows you to efficiently reuse previously retrieved or computed data. [1]

Similarly one may ask, What is distributed caching and how does it work? In a distributed caching environment, the data can span multiple cache servers and be stored in a central location for the benefit of all the consumers of that data.

[3]
