Every consumer uses some kind of device or application, and every time it is accessed, data is extracted. This data must be stored so that the next time the user accesses this device, it can be retrieved more quickly. The cache makes all of this possible.
What is a cache?
A cache is a hardware or software component set in an application or device memory. The cache automatically and temporarily stores data consumed by the user. So next time the application or device is accessed by the user the time and effort will be reduced.
A cache stores information such as pictures, instructions, and even programs on the computer, phones, or other devices. So they could be available when the user needs them again. When it comes to storing recently accessed web pages it’s called web caching or HTTP caching.
What is web caching (or website caching)?
Web cashing occurs after the user returns to a previously visited page. But the page that is shown is a version from this cache rather than a ‘fresh’ one. And the content on the page is shown much faster than the first time.
The disadvantage of websites with changing content, changes may not be visible if a previous, cached version is called up. Often only part of the site is cached. For example, if it’s some content web page the overall look will be cached but the articles on the page (the static content) will load completely fine on every visit.
Types of web caching
There are two types of web caching such as server-side caching and client-side caching. Although they cache websites differently, their purpose is the same – to make websites load faster without making new requests from the origin source.

What is Server-side caching?
Server-side caching temporarily stores web files and data on the origin server for later use. So when the user visits the website again he will see that already saved (or cached) copy of the webpage with better speed.
What is Client-side caching?
Client-side caching (also called browser caching) temporarily stores the copy of a webpage in the browser’s memory (a folder created by the browser). So when the user visits the website again with client-side caching enabled, he will fetch the data from the browser cache folder located on the user’s device.
