Using the best Caching Plugins for WordPress is one of the solutions to boost the speed of your website.
Concept of Caching
A cache is a collection of data to transfer from source to destination in an effective way. Whenever the information is needed, the data can be extracted from the temporary storage location. This helps the users to access the desired data in a quick frame of time.
The concept of caching is not only useful to load the website faster but also it helps to improve the website performance. If there are a lot of visitors at the same time on your site, then the website has to collect information from the database before it is sent to the browser. Due to the repeating of this process, the site may slow down.
In order to prevent this, the caching plugin stores a copy of your page when the side loads once. Then it shows the cached version to other users.
