 Here, we will discuss about the Front-End and back-End technologies for the web development. Also discuss which are the top Front-End and back-End languages and technologies 

Back End

 What is Back-End? 

Back end refers to the server-side of web development. It focuses on everything that happens behind the scenes to ensure that the front-end of a website or application functions correctly. 

The back end is responsible for server logic, database interactions, user authentication, and business logic. 

It involves managing requests from the front end, processing them, interacting with databases, and returning the appropriate information to be displayed on the user interface.
