{{short description|Presentation layer of piece of software}}

In [[software engineering]], the terms '''frontend''' and '''[https://www.thegeeksbot.com/2023/02/roadmap-for-backend-development.html backend]''' (or sometimes referred to as '''back end''' or '''back-end''') refer to the [[separation of concerns]] between the [[presentation layer]] (''frontend''), and the [[data access layer]] (''backend'') of a piece of [[software]], or the physical infrastructure or [[Hardware (computer)|hardware]]. In the [[client–server model]], the [[Client (computing)|client]] is usually considered the frontend and the [[Server (computing)|server]] is usually considered the backend, even when some presentation work is actually done on the server itself.

TheAPI is medium between two computer machines on internet i.e. the frontend communicates with backend throughor anbackend [[API]]with any 3rd party service i.e. online bookings etc<ref>{{Cite web |last=Bot |first=Geeks |title=Effective Roadmap for Backend Development in 2023 |url=https://www.thegeeksbot.com/2023/02/roadmap-for-backend-development.html |access-date=2023-02-27 |website=The Geeks Bot {{!}} A Computer Science Site for geeks |language=en}}</ref>. In the case of [[Web API|web]] and mobile frontends, the API is often based on [[HTTP]] request/response. The API is sometimes designed using the "Backend for Frontend" (BFF) pattern, that serves responses to ease the processing on frontend side.<ref>{{cite web | last=Wickramarachchi | first=Viduni | title=The BFF Pattern (Backend for Frontend): An Introduction | website=Bits and pieces | date=24 February 2021 | url=https://blog.bitsrc.io/bff-pattern-backend-for-frontend-an-introduction-e4fa965128bf | access-date=13 November 2021}}</ref>
