The term “back-end” refers to the server-side of a software application or a website which the user does not interact with directly. It’s essentially all the technology needed to process the behind-the-scenes functionality of a web application. This includes databases, servers, applications, and any other system the user doesn’t interact with directly, but that is required to serve and process the user’s requests.

Key components of back-end systems often include:

Server: This is the computerized system that hosts the application or website.

Application: This is the actual program running on the server, which processes the user’s requests.

Database: This is the technology used to store all the data needed by the application or website. It could be user profiles, product information, or any other necessary data.

The back-end system typically includes a server for running the back-end application, a database for storing data, and the back-end application itself, which handles requests from the front-end, processes the data, and sends a response back.

The back-end application is written in server-side programming languages, which can include Java, Python, Ruby, PHP, .Net, Node.js, among others. It’s also responsible for server-side rendering of websites, transaction processing, and more.

The front-end, on the other hand, is the user-facing side of a website or software—the interface with buttons, forms, and other elements with which the user interacts. It communicates with the back-end and displays the results to the user.

Together, the back-end and the front-end constitute the full stack of a web application.
