In computer networking, front end can refer to hardware that connects devices to the network, provides security such as a DMZ, or converts data into a transportable format. Some graphical user interface (GUI) applications act as a https:\/\/dnews7.com\/common-technical-product-manager-interview-questions-and-what-you-need-to-know.html<\/a> thin front end for underlying command-line interface (CLI) programs, to save users from having to learn the CLI terminology and commands. The back end, or server side, usually resides on the server, often far removed physically from the user. The front end is an abstraction, simplifying the underlying components by providing a user-friendly interface, while the back end handles data storage and business logic. Examples might be simplified to improve reading and learning. The rest are also important, but without those three basic ones, you can\u2019t apply any of the others.<\/p>\n<\/p>\n
