Internet and Web

An applet is a small Java program designed to run within a web browser as part of an HTML page. Applets were a key feature of Java in the late 1990s for bringing dynamic content to the web before modern JavaScript frameworks. They execute in a sandboxed JVM on the client side.

Pharming is an attack that redirects users to fake websites by compromising DNS settings or poisoning DNS caches, unlike phishing which requires clicking a link. Option C is correct. Session hijacking (A) steals user sessions, phishing (B) uses deceptive links, and MAC spoofing (D) forges hardware addresses.

Lynx is a classic text-based web browser that runs in terminal environments. It allows users to navigate and read web content without any graphical interface, making it useful for remote systems or accessibility needs. It's been a staple Unix utility since the early days of the web.

The navigator object provides browser information via navigator.appName. Option B is correct. Options A and C reference non-existent objects (browser, client), and option D claims all are correct which is false.

The getVersion() function in ActionScript returns a string containing Flash Player version and platform information. This includes details like the operating system (WIN, MAC, UNIX) and the Flash Player version number. There is no function named getFlashVersion() or getLatestVersion() in standard ActionScript.

sendError() and sendStatus() are methods of HttpServletResponse that send HTTP error responses and status codes to the client. HttpServletRequest handles request data, while ServletRequest and ServletResponse are generic interfaces that HttpServlet extends.

The World Wide Web Consortium (W3C) is the international standards organization that develops and maintains web standards including HTML, CSS, and HTTP specifications. Microsoft, Mozilla, and Sun Microsystems are companies that implement these standards but do not create them.

The correct HTML for a hyperlink uses the tag with the href attribute specifying the URL. The clickable text goes between the opening and closing tags. The 'url' and 'name' attributes don't exist for links. Option C shows correct syntax.

To create a clickable e‑mail link you must use the <a> element with a mailto: URI scheme, e.g. </a><a href="mailto:xxx@yyy">. The other tags either do not exist in HTML or lack the required scheme, so the stored answer is correct.

Standalone utilities in DB2 are also known as offline utilities because they must be run when the subsystem is not active. They operate directly on data sets outside of DB2 control. Online utilities run while DB2 is active. 'Private' and 'Public' are not standard classifications.

HTML forms without a method attribute default to GET (option C). The form data is sent in the request body for GET requests (option F). Options A, B, D, E are incorrect: GET (not HEAD or POST) is used, and both fullName and sbmButton parameters are sent in the body, not URL. The question asks which statements are true - options C and F correctly describe the default GET behavior and parameter passing.

The jsp:useBean action supports four scope values: page (default, current page only), request (current request), session (user session), and application (entire web app). All listed options are valid scopes.

In JSP, implicit objects (also called predefined variables) are automatically available to JSP pages without declaration. These include request, response, session, application, out, config, page, and pageContext. They are called 'implicit' because the container creates them automatically - developers don't need to declare or instantiate them.

The setCenter method is required immediately after creating a map using the Google Maps constructor to specify the map's center point and zoom level. Without this, the map would not know where to focus. Options A, B, and C either use incorrect method names or improper syntax.

The setcookie() function in PHP sends a cookie to the browser, storing data in a cookie variable that will be sent back with subsequent requests. It does not declare variables (that's just variable assignment) nor does it enable/disable cookie support (that's controlled by browser settings).
