Internet and Web

WWW stands for World Wide Web, which is a system of interlinked hypertext documents accessed via the Internet. World Wide Wrestling, World War Won, and Whole Wide World are all incorrect expansions of this acronym.

Webcrawler was one of the early web search engines. Netscape is a web browser, Java is a programming language, and Internet is the network itself - none of these are search engines.

HTML (HyperText Markup Language) is the standard language for creating web pages. HTTP is a protocol for transferring data, FTP is for file transfers, and URL is an address format - none are languages for writing web pages.

Netscape was a pioneering web browser software. World Wide Web is the system of interconnected documents, Launcher is not a browser, and E-mail is a communication system - none of these are browsers.

Underlined text on web pages typically indicates a hyperlink (link) that connects to another page or resource. While important words can be underlined, and web addresses appear as links, the primary purpose of underlining is to identify clickable links.

Internet Explorer is a web browser used to access and view websites. It is not a graphing package, news reader, or search engine - those serve different purposes.

HTTP stands for Hyper Text Transfer Protocol, which is the foundation of data communication on the World Wide Web. The other options are made-up phrases that don't represent real protocols.

Hotmail.com was a free web-based email service where users could create email accounts. GRE.org is for test registration, Syvum.com is an educational site, and Linux.org is about the Linux operating system - none offer email account services.

In Google search, using 'define:' followed by a word shows definitions from multiple sources. Just typing the word (A) searches normally, 'definition:' isn't the correct operator, and '?quiz' isn't a standard search operator for definitions.

Google can do math directly in the search bar. Just type the expression as-is: ((2*6)/3)^2. You don't need special operators like 'calculate:' or 'show results:'. Option D is incorrect - Google handles mathematical calculations natively.

The 'related:' search operator finds sites similar to the specified URL. 'like:' and 'showlike:' aren't valid Google operators. The 'link:' operator shows pages that link TO the site, not related sites.

The 'link:' operator finds all pages that contain links to the specified URL. 'show links' isn't a valid operator syntax. Option C is missing the colon, and 'references:' isn't a Google search operator.

Cyberphobia is the fear of computers, specifically anxiety about using or working with computer technology. While it can manifest as fear of the internet or emails, the core phobia is about computers themselves. It's a specific technological anxiety.

Facebook was originally called 'TheFacebook' when launched at Harvard in 2004. The name was simplified to just 'Facebook' when the service expanded beyond Harvard.

Amazon is primarily an e-commerce and cloud computing company, not a social networking site. MySpace, Fropper, and Orkut were all social networking platforms where users created profiles, connected with friends, and shared content.
