What is Client-Server Model?

The client-server model is the main architectural computing model that most of the internet is based off of, with the "client" being the front-end of the system, and the "server" being the back-end of the system. The client side of a computing system is the portion of the platform that the user interacts with directly through their screen or graphical user interface (GUI), and the server side is the portion that the user doesn't see that is responsible for the majority of the system's operational efficiency. Client-server models in computing have been implemented since the beginning of the internet.
