Cache is a collection of data—duplicates of original values—that is stored in a separate 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
