Internet and Web

In a content URI like content://contacts/people/3, the 'authority' is 'contacts'. The authority uniquely identifies the content provider and is typically the package name or a custom string. It appears after the 'content://' scheme.

WebView is the correct Android widget for displaying web content within your application. It uses the WebKit rendering engine and provides methods for navigation, JavaScript execution, and webpage loading. WebkitView is not a standard Android widget class.

HTTP 404 errors fall under the 4xx series, which indicates client errors. Specifically, 404 means 'Not Found' - the client requested a resource that doesn't exist on the server. The question has an error - it says '404 bad request error' but 400 is 'Bad Request' while 404 is 'Not Found'. Despite this terminology issue, the core concept is correct: 404 indicates a client-side error (the client asked for something that isn't there), not a server failure, success response, or redirection.

Android's integrated browser is built on the WebKit rendering engine. WebKit provides the core functionality for rendering web pages and running JavaScript within Android applications. Safari uses WebKit on iOS, while Firefox uses its own Gecko engine.

MVC's separation of concerns creates loose coupling between Model, View, and Controller. The routing engine generates clean, SEO-friendly URLs without file extensions. By organizing code into distinct layers, MVC applications are generally less complex to maintain than monolithic alternatives.

HTTP status code 200 OK indicates a successful request. 304 is Not Modified (cached), 404 is Not Found (error), and other 4xx/5xx codes indicate errors. 200 is the standard success response for GET, POST, and other successful HTTP requests.

XMLHttpRequest (XHR) requests are AJAX calls that fetch data asynchronously without reloading the page. These requests do not create new history entries - only page navigation through hyperlinks, window.location, or form submissions add to browser history. Therefore, the statement is false.

Information is processed, organized data that provides meaning and context. While gossip and rumors are informal and unverified information, and font is a typography style, data is the fundamental raw material that becomes information when structured and interpreted.

WCF services are structurally exposed to external clients using endpoints, which consist of an Address, Binding, and Contract (ABC). Web references and direct URL references are client-side techniques for consuming services rather than exposing them.

Flex (Adobe Flex) was a rich internet application framework used for building Flash-based web applications. In the context of the Answers.com portal (answersint), Flex was indeed used as the frontend technology. Dot Net (A) and JSP (B) are server-side technologies, while Silverlight (D) was a competing RIA framework from Microsoft.

WebI provides drill up (navigate to higher hierarchy level) and drill down (navigate to more detailed level) as standard analysis features. Drill by allows drilling on a specific dimension or hierarchy. While drill through exists, it's not typically listed as a standard drill option in the same category.

In the AAA security framework (Authentication, Authorization, Accounting), a user session begins after successful authentication. Once authenticated, the user's identity is established and a session can be tracked. Authorization determines what the authenticated user can access.

User sessions terminate through valid mechanisms: user logout (explicit termination), session expiration (timeout), or administrative action (disabling user account). Hitting another URL is just session activity, not termination. All three listed scenarios are correct.
