Internet and Web

VI (and its modern variant vim) is a powerful text editor that comes pre-installed on virtually all Unix/Linux systems. It's known for its modal editing interface and keyboard-only operation.

Website response time becomes unacceptable when it exceeds 15 seconds. While 8 seconds is considered the upper bound for 'good' response time, 10-12 seconds is poor but still tolerated. 15+ seconds is widely regarded as the threshold where users abandon the site or the experience is completely unacceptable.

HP Quality Center 9.2 was designed primarily to run on Microsoft Internet Explorer (IE) due to its heavy reliance on ActiveX controls, which were not natively supported by other browsers like Firefox or Safari.

RIA stands for Rich Internet Applications. These are web applications that have the functionality and features of traditional desktop applications, typically running in a browser but offering rich user interfaces and responsive interactions. RIAs often use technologies like Flex, Silverlight, or AJAX.

In web context, 'stickiness' refers to a website's ability to retain visitors and encourage repeat traffic. High stickiness means users spend more time on the site and return frequently. Option A is a joke about weather. Option C describes page load time, not user retention. Option D refers to navigation between pages.

In web terminology, a portal is a gateway or entry point to web-enabled applications and sites. It aggregates content and services from multiple sources into a single interface. Option A is a literal definition (portal as doorway). Option C is a physical office concept. Option D is unrelated.

Web syndication is a form of syndication in which website material is made available to multiple other sites or individual subscribers through feeds, allowing reuse of content.

Session management in web applications can use all three methods: cookies (store session ID on client), URL rewriting (append session ID to URLs), and hidden form fields (pass session ID in forms). Each has trade-offs in security and usability. Using multiple methods provides fallback options.

Web 2.0 refers to the paradigm shift where the internet acts as a platform for user-generated content, usability, and interoperability, rather than just static pages.

When anonymous users connect to an IIS web site, they are authenticated using the built-in IUSR_computername account (e.g., IUSR_SERVER01). This account is created automatically during IIS installation and is used for anonymous authentication. The account name uses the computer name, not domain name or virtual directory name.

The HTTP 404 Not Found client error response code indicates that the server cannot find the requested resource or page. Other options like 505 (HTTP Version Not Supported) or 550 (FTP error) are incorrect.

YAHOO stands for 'Yet Another Hierarchy of Officious Oracle'. This was the original expansion chosen by founders Jerry Yang and David Filo. 'Officious' refers to being helpful or intrusive, reflecting the directory's nature.

HTML defines four predefined target names for links: _blank (opens in new window/tab), _self (opens in same frame - the default), _parent (opens in parent frameset), and _top (opens in full original window). There is no predefined target named '_son' - this is a made-up name that does not exist in the HTML specification.

Clicking the logo in the top-left corner is a widely recognized convention for returning to a homepage. This pattern works across all types of websites and requires no explicit 'home' label. While home links (B) and home icons (D) are also valid, the logo is the most intuitive and consistently placed element. Browser back button (A) is unreliable for homepage navigation.
