Cache, pronounced as ‘cash’, is a term used for temporarily stored data that accelerates the loading speed of a website.
Cache in WordPress refers to the temporary storage of data, usually requested by visitors, to speed up the loading time of a website. Caching is an important technique to improve website performance, reduce server load and decrease page loading times.
In WordPress, for example, cache creates a static version of your posts and pages and serves them to visitors. Since static pages are usually rendered fast in the browser, it makes your site load faster.
In WordPress, caching can be achieved through various methods such as plugins, server-level caching, content delivery networks (CDNs), and browser caching. Popular WordPress caching plugins include WP Rocket, W3 Total Cache, and WP Super Cache, which can be used to create and manage cached copies of pages and posts.
