What is rear end and front end?

In web development, the "front end" refers to the client-side part of a website or application that users interact with directly, encompassing elements like design, layout, and user interface. The "rear end," or back end, involves server-side functionalities, including database interactions, server logic, and application performance, which users do not see but are essential for processing requests and delivering data. Together, both ends create a complete user experience, where the front end presents information and the back end manages data and business logic.
