back end

also seen as: back-end

The portion of a program that accomplishes the processing tasks the program is designed to perform. In a LAN with client/server architecture, the back end app may be stored on the file server while the front end programs handle the user interface on each workstation. "Back end" also refers to behind-the-screens technology, which administers tasks or processes (such as database inventory management) while allowing users to easily add or delete information via a simple front end interface.
