What do you mean by Caching and What are its types?

Answer»

Caching is basically a technique or process of storing data somewhere or in the cache for future REQUESTS. The cache is a temporary storage area. Caching keeps all frequently or recently accessed files or data in the cache memory and accesses them from the cache itself rather than actual ADDRESS of data or files. The cache interface simply improves the storage mechanism for request/response object pairs that are being cached.

  • It is considered the best solution to ENSURE that data is served where it is NEEDED to be served that too at a high level of EFFICIENCY which is best for both client and server.
  • It delivers web objects faster to the end-user.
  • It reduces load time on the website server.
  • It leads to faster execution of any process.

  • Page Caching
