HTML or “Hypertext Mark-Up Language” is a “marking” language whose role is to formalize writing a document with formatting tags. The language is nowadays most commonly used in the creation of webpages. The tags allow you to specify how the document should be presented and the relationship it has with other documents.
The tags used are written in between angle braces. For example, <html>.
HTML allows the playback of documents on the Internet from different computers, thanks to the HTTP protocol, allowing access via the network to documents identified by a unique address, called a URL.
The World Wide Web (WWW for short), or simply Web is a “virtual canvas” formed by the various documents (called “web pages”) linked together by means of hyperlinks.
Web pages are usually organized around a home page, playing a central point in the navigation using hyperlinks. This coherent set of web pages linked by hyperlinks and centered around a common home page is called web site.
The Web is a huge living archive composed of a myriad of websites offering web pages that may contain formatted text, images, sounds, video, etc.
