The backend of a web application is an enabler for a frontend experience. Backend code is run on the server, as opposed to the client. This means that backend developers not only need to understand programming languages and databases, but they must have an understanding of server architecture as well.
Likewise, what is the meaning of front end and back end?
"Front-end" typically means the parts of the project a user interacts with--such as the graphical user interface or command line. It's a vague term, there isn't an exact definition. "Back-end" means the parts that do the work, but the user is unaware of or cannot see. Databases, services, etc.

What is a backend developer?
This type of web development usually consists of three parts: a server, an application, and a database. Code written by back end developers is what communicates the database information to the browser. Anything you can't see easily with the eye such as databases and servers is the work of a back end developer.
