To load a webpage, there’s a behind-the-scenes process where information (queries) is sent to and from the database. Specifically, queries in PHP language are sent to the site’s database, retrieving data and generating it into an HTML page that’s returned for display on the website.
This multi-step process requires significant processing power, which causes delays in loading the content.
At its core, “caching” is the act of storing essential data in an easily accessible location to serve it quickly to visitors. It involves creating a static version of the content, eliminating the need to retrieve all that information again, resulting in faster performance and improved load times.
