What is HTML?
HTML is short for Hypertext Markup Language. It is the foundational language used to create websites and all browsers use HTML to determine how to display content.
What is CSS?
CSS stands for Cascading Style Sheets. It is the language that tells the web browser how to display fonts, colors, layouts, and much more. CSS also enables the creation of responsive websites, where the presentation changes based on the device and screen it’s being viewed on.
What is XML?
XML is an acronym for eXtensible Markup Language. Similar to HTML, it is a markup language, but used for different purposes. XML is self-descriptive and used more to transport and store data. Where HTML builds the framework for how a webpage is displayed, XML handles the data transfer.
What is JavaScript?
JavaScript (JS) is a programming or scripting language used primarily in web development. It enables you to perform more advanced and complex features on websites than HTML and CSS. Nearly every time a user interacts with an element on a page, that element is using JavaScript.
What is AJAX?
AJAX is an acronym for Asynchronous JavaScript and XML. It is a way to create highly dynamic, fast performing web pages. It allows websites to update small sections at a time, rather than reloading the entire page, resulting in a better user experience.

What is CORS?
CORS is an acronym for Cross-Origin Resource Sharing. It is critical to HTML5 and pertains mostly to front-end developers. It enables the web developer to use resources from different domains outside of the one being worked on.
What is an API?
API stands for Application Programming Interface. It enables different applications to transfer information back and forth and work together. For example, the Twitter API could communicate with a website to display, share, or comment on tweets without changing to the official Twitter platform.
