Internet and Web

The Internet is a global public network open to everyone. An Intranet is a private internal network accessible only to defined authorized users within an organization (like employees). Intranets use the same technology as the Internet but are restricted and secured behind firewalls.

This is a factual question about Citigroup Global Services Limited (CGSL) internal infrastructure. Corporate intranets typically use .net or internal domains rather than public .com sites. Without external verification of CGSL's actual intranet URL, I must accept the provided answer key, though this is organization-specific knowledge not general computer literacy.

VI is a standard, powerful terminal-based text editor found on almost all UNIX and Linux systems. It is not used for E-mail, FTP, or Telnet services, which have their own dedicated clients and protocols.

The World Wide Web Consortium (W3C) is the international standards organization that develops and maintains web standards including HTML, CSS, HTTP, and other web technologies. While companies like Mozilla, Google, and Microsoft implement these standards in their browsers, W3C provides the collaborative framework where standards are developed.

The tag with the href attribute is the correct syntax for creating hyperlinks. The href attribute specifies the destination URL. Options A and C use incorrect attributes (url and name), while option B is missing the href attribute entirely.

The target="_blank" attribute is the correct way to open links in a new browser window or tab. The _blank value is a reserved keyword that tells the browser to open the link in a new window. Options A, B, and C use incorrect or non-standard values.

In HTML, the href (hypertext reference) attribute specifies the URL or address that the link points to. Without href, an anchor tag wouldn't have a destination. Target only controls the opening behavior, not the address itself.

Amazon is primarily an e-commerce platform for buying and selling goods, not a web search engine. Google, Zeal, and Hotbot are all search engines designed to index and search web content.

iMacros is a free Firefox add-on for recording and automating web interactions. While other automation tools exist, the question specifically asks for free Firefox add-ons, and iMacros fits this description. 'Macros' alone is not specific enough and 'both' is incorrect.

WATIR stands for Web Application Testing in Ruby. It is an open-source family of Ruby libraries for automating web browsers. The key distinction is 'Web' not 'Windows' and 'Application Testing' not 'Automation Testing'.

Quality Center 9.2 (now HP ALM) was designed for Internet Explorer as the primary supported web client. During that era, enterprise applications heavily relied on IE-specific technologies like ActiveX. Modern browsers like Firefox and Safari lacked necessary plugin support. Netscape was already obsolete by QC 9.2's release. IE's dominance in enterprise environments made it the practical choice.

To check if a cookie has been set, use isset() on the appropriate $_COOKIE superglobal key - for example, isset($_COOKIE['cookiename']). The setcookie() function is used to SET cookies, not check them. There is no iscookie() function in PHP.

Ajax, REST, JSON, and RSS are all core technologies associated with Web 2.0. SOAP is an older, heavyweight protocol. However, since all listed options are Web 2.0 technologies, 'None of the above' is correct.
