Caching is the process of collecting duplicates of original data values, that are then stored (cached) in a location that is easier to access for enhanced performance.

The following are just a few examples of the different types of cache:

  • CPU Cache: A small area of fast memory used by the central processing unit.

  • Database Cache: Temporary storage of database content in multi-tier applications.

  • Query Cache: Temporary storage of query data and metadata to increase performance.

  • Web Cache: Temporary storage of web documents to increase performance.
