What is Front-end and Back-end? [duplicate]

8

I'm beginning to study WEB and I still lack a lot of knowledge, and right from the start I came across the terms that are highly used in this WEB development world, which are Front-end and Back-end , I have read a few articles about it, but I am still in doubt and can not understand these terms. I would like to know what is Front-end and Back-end , what languages and technologies belong to Front-end and what are the ones that belong to the Back-end and what are the differences between them?

Unlike desktop programming where almost every feature is available on the local machine, the most important thing in web programming is to understand protocol cycle http , a request is made by the client the server processes the request and returns something (a text, usually in html notation).

The front-end termno refers to the features developed in the 'client' part of the software, some tools are javascript and css.

Back-end is the term used to define built-in server-side functionality.

Very simply:

Front-end is what the user will see, usually done in HTML and JavaScript.

Back-end is what will be processed from behind on the server. The user does not have access, the backend is also responsible for building the front end for the user. Usually PHP is used but it can be done in any other language.

Two very common terms in the web and front-end community that you can refer to client-side and back-end server-side.

Some languages like css, html and js only require the client browser to work. while server-side php, C # languages need a server.

I recommend reading: What is client-side and server-side ?
