Similarly, how does the backend work?
Backend. The backend usually consists of three parts: a server, an application, and a database. If you book a flight or buy concert tickets, you usually open a website and interact with the frontend. Once you've entered that information, the application stores it in a database that was created on a server.
Similarly, how the front end and the back end relate to presentation and application layers? The frontend of a website is the part that is presented to the user; the parts that you see and interact with when you browse the web. The backend is the technology behind that presentation layer that makes everything work, i.e. the server, application and database.
Moreover, what is the difference between frontend and backend?
Frontend refers to the client-side, whereas backend refers to the server-side of the application. Both are crucial to web development, but their roles, responsibilities and the environments they work in are totally different. Frontend is basically what users see whereas backend is how everything works.
