Graceful Degradation:
Graceful degradation refers to the ability of a website to have elements that take advantage of the capabilities of newer web browsers in a way that allows users with older web browsers to still view the site in a manner that at least allows access to basic content. It also applies to making sure that if one small portion of your site doesn’t work in someone’s browser, it doesn’t break your entire site for them.
Graphical User Interface:
GUI is the acronym for a Graphical User Interface. A GUI uses an input device (like the mouse) and visual representations of how the user is able to interact with a web application. In other words, it’s all the front-end stuff you see on a web application. Its purpose is to allow you to interact with a web application without having to enter code.
