HTML stands for Hypertext Markup Language, which is the standard language used to create and design webpages by structuring content and hyperlinks.

Search engines maintain databases (indexes) of web pages on various topics, enabling users to find relevant information quickly. Newsgroups and news servers are related to discussion forums and message distribution, while the World Wide Web is the entire system of interlinked web pages, not a database maintainer.

The domain ".com" is primarily used by commercial or profit-oriented businesses, whereas ".edu" is for educational institutions, ".org" is typically for non-profit organizations, and ".net" was originally intended for network providers.

A web browser is the software used to access the World Wide Web (www). It allows users to retrieve, present, and navigate web pages. MS Word, Adobe Reader, and Excel are not designed for web browsing.

In Google Chrome, pressing Ctrl + D opens the dialog to bookmark the current web page, allowing you to save it easily. The other shortcuts perform different functions: Ctrl + H opens history, Ctrl + K moves the cursor to the address bar for search, and Ctrl + U views the page source.

HTML (HyperText Markup Language) is the primary language used to create and structure content on the web, making it the major language of the web.

Web pages are primarily written using Hypertext Markup Language (HTML), which structures the content on the web. The other options do not represent languages used for writing web page code.

Tim Berners-Lee's first web browser was originally named WorldWideWeb but was later renamed Nexus to avoid confusion between the software and the information space (the World Wide Web).

The original question asks which format is widely used for transmitting streaming video data on the internet. The options given are MP3, AVI, WMA, and WAV. Based on authoritative sources, the formats MP3, WMA, and WAV are primarily audio formats and are not used for video streaming. AVI is a video container format but is not widely used for streaming video on the internet. Instead, modern streaming commonly uses formats like MP4 (with H.264/AVC codec), WebM, and others. However, since the question's options do not include these common streaming formats, and AVI is the only video format listed, AVI is the best choice among the given options, though it is not the most accurate representation of widely used streaming formats. Therefore, the correct answer remains B (AVI) given the options, but it should be noted that AVI is not the standard for internet streaming video today. The explanation is updated to clarify that AVI is a video format (unlike the other audio-only options) but is not the most common streaming format currently used on the internet.

Mosaic, developed in 1993 by Marc Andreessen and others, was one of the first widely used graphical web browsers, which helped popularize the World Wide Web.
