What is cache?

In the world of information technology, the term"cache"refers to a typeof temporary storage that serves to speed up access to frequently used data.

In relation to websites, a cache stores certain elements of a web page, such as HTML files, CSS stylesheets, JavaScript files, and media files, so that they do not have to be reloaded from the server each time the page is accessed. The advantage of caching is thatit reduces loading timesandreduces the load onthe server, as files are stored locally and can therefore be accessed more quickly.

What types of cache are there for websites?

  1. Browser cache:This is wherethe web browser stores data from a website on the user's device. When the user visits the site again, the browser loads the stored data, which reduces the loading time.

  2. Server cache:Thistype of cache is set up on the web server. Frequently requested content is temporarily stored here so that requests can be responded to more quickly. This reduces the server load and improves response times.

  3. Content Delivery Network (CDN) cache:ACDN distributes copies of website content across various geographically distributed servers. This ensures that users can retrieve content from a server that is closest to them, significantly reducing loading times.

  4. Application cache:Someweb applications use their own cache to temporarily store data and states, which is particularly helpful for dynamic applications.
