What exactly is the backend?

The back end refers to parts of a computer application or a program’s code that allow it to operate and that cannot be accessed by a user . Most data and operating syntax are stored and accessed in the back end of a computer system. Typically the code is comprised of one or more programming languages.

Front and back end developers work on different sides of a website. Front end development is programming which focuses on the visual elements of a website or app that a user will interact with (the client side). Meanwhile, back end development focuses on the side of a website users can’t see (the server side).

The back-end is the code that runs on the server, that receives requests from the clients, and contains the logic to send the appropriate data back to the client . The back-end also includes the database, which will persistently store all of the data for the application.
