Explain the meaning of a web address?

What is HTTP?

Short for HyperText Transfer Protocol, the underlying protocol used by the World Wide Web. HTTP defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands. For example, when you enter a URL in your browser, this actually sends an HTTP command to the Web server directing it to fetch and transmit the requested Web page.

What is (WWW) World Wide Web?

The World Wide Web (abbreviated as WWW or W3, commonly known as the Web ), is a system of interlinked hypertext documents accessed via the Internet. With a web browser, one can view web pages that may contain text, images, videos, and other multimedia, and navigate between them via hyperlinks.

What is the address of an website?

It's also known as the term "Web address", which is a synonym for address bar (also location bar or URL bar) that uses the HTTP / HTTPS protocol. This is a feature in a web browser that either shows the current URL or accepts a typed URL that the user wishes to go on to. Most address bars offer a list of suggestions while the address is being typed in. Auto-completion bases its search on the browser history.

What is the extension, like .COM , .BLOG, .ORG ....?

(1) An extra feature added to a standard programming language or system.

(2) In DOS and some other operating systems, one or several letters at the end of a filename. Filename extensions usually follow a period (dot) and indicate the type of information stored in the file. For example, in the filenameEDIT.COM, the extension is COM, which indicates that the file is a command file. (Depending on the operating system, the punctuation separating the extension from the rest of the filename may or may not be considered part of the extension itself.)
