Of or relating to the part of a software system or online service that the user does not interact with and that is usually accessible only to programmers or administrators: back-end software. The Free Dictionary.
Example 1: The IT administrator logged in to the back-end of the program to change user permissions for the manager.
Example 2: Our company is seeking a Junior Full Stack Developer, who will work with back-end code, as well as front-end user interface design.
With business software, the term back-end can refer to anything customers and most employees never see, such as database queries and code. With websites, the back-end is virtually anything not seen on the front-end by normal visitors to the site.
With WordPress however, the term back-end refers to something specific:
The back end is the area that authorized users can sign into to add, remove and modify content on the website. This may also be referred to as “WordPress”, “admin” or “the administration area”. WordPress Codex Glossary.
The back-end of WordPress is primarily the administrator panel, but also includes anywhere you can post or modify content or settings. When used as a verb rather than a noun, adding content is a back-end action which requires login and privileges on that blog. On the other hand, commenting, liking, and sharing are front-end actions available to site visitors.
The Other Back-End
WordPress technically has more than one back-end. Users of WordPress.org open source software can modify settings in code to change the appearance and behavior if their installation of the software.
Example : A WordPress freelance developer modifies code on the back-end of the software to change the appearance of administrator panel for their client. The client has no access to the code, and modifies content by logging into their back-end: the administrator area.
Additionally, the developers of WordPress software itself modify code within the software when they release new versions. For WordPress software developers, the front-end of their product is the administrator panel interface, since their primary audience is blog owners, while the blog owners primary audience is their blog visitors.
Example : WordPress.org hires back end developers to work on the code of their software. They release new versions, which website developers download and set up for their clients.
In the above example, each of these three persons have their own understanding of back-end access. One client’s back-end is another developer’s front-end.
