Front-end vs Back-end

In web development, the phrases "front-end" and "back-end" are sometimes used interchangeably. But what do they actually mean?

Here, we outline the distinctions between the "front-end" and the "back-end." The "front-end" is, to put it simply, what users or visitors see when they engage with a platform, program, or application. Programmers design processes on the "back end" to ensure that those exchanges go without a hitch.
