When a website is requested repeatedly from different clients, reusing the previously generated data to speed up new requests is called WordPress caching.

Purging the Cache

Purging cache means that re-cache all old cached data. This means previous is deleted and generates the new one. Some Purging cache is following:

Database query caching:

The database is very important for every company or every project. The database is used to store, updates, deliver and retrieve data efficiently.
