Cookies vs Cache vs Session – Definition
Web cookie, also named browser cookie/internet cookies/HTTP cookie, is a small amount of data that is stored on your computer by the web browser when you browse a web page. Cookies are used for remembering user’s browsing activity, e.g. clicking specific items or buttons, logging in information like names, passwords, addresses, payment card numbers, visited web pages, etc.
What is cached data? Web cache, also called HTTP cache, is a tech for storing temporary information like web pages, images, files, scripts or other web multimedia. Cache is mainly used to reduce the server lag and reduce the loading speed of web page data.
In the computing world, session is the temporary interactive information between multiple communicating devices or between the user and computer.

Difference between Cache and Cookies
- Cache’s function is to make the web page load faster while cookie’s function is to track user’s different browsing activities.
