What is Cache?

The cache is a collection of data that temporarily stored for immediate access if needed.

In our local computer, we cached data in the hard disk, when needed, the information is exhibited after doing various processes.

What Caching does is it processes the frequently requested information and keeps it in temporary memory. As a result, when needed, computers access the file very quickly.

The same things happen in WordPress. Each time a visitor visits your website, WordPress fetches data from the database. So here it comes to caching plugin when visitors first visit your site, Caching plugin saves the data. Then again, the viewer visits your website, WordPress does not fetch the data from the database from temporary memory that is what cache plugin collected.

Caching allows your WordPress site to skip a lot of steps. Instead of collecting data from a database that needs a lot of time, your caching plugin generates a copy of the webpage after the first load and then every time it serves a cached version to your user.

Why is Caching Important?

It lessens the load time on your WordPress hosting servers and makes your website run a lot quicker. If you set up your cache very precisely, Your website speed and performance is improved.
