The tag defines the browser tab title, not visible page content. It appears in the browser window title bar or tab, not as text on the webpage itself. To display large bold text on a page, use heading tags like

through

in the body section.

The anchor tag is versatile and can link to specific locations within the same page (using # with id), other pages on the same website (relative paths), or any page on the internet (absolute URLs). This flexibility makes it fundamental for web navigation and creating interconnected content.

CSS files always use the .css extension as the standard file naming convention. .xml is for XML data files, .ccs is not a recognized extension, and .xhtml is specifically for XHTML documents.

CSS uses curly brackets { } to contain style declarations for selectors. HTML uses angle brackets < > for tags, while parentheses ( ) are used in CSS for functions like calc(), url(), or rgb().

XML stands for eXtensible Markup Language. Option B correctly identifies this full form (capitalization varies). The key word is 'extensible' meaning it can be expanded with custom tags, unlike HTML which has fixed tags. Option A incorrectly uses 'Extensive' and C/D use wrong prefixes.

JavaScript is the common name for the language, but the official specification maintained by ECMA International is called ECMAScript. The language is standardized under this name to ensure consistency across different implementations (browsers, Node.js, etc.).

HTML uses the tag to embed JavaScript code. Other tags like <javascript>, <java>, <insert>, or <language> are not valid HTML elements.

AJAX stands for Asynchronous JavaScript and XML. It's a web development technique that allows web applications to send and receive data from a server asynchronously without interfering with the display and behavior of the existing page, making web applications more responsive and dynamic.

XML stands for eXtensible Markup Language, not eXtensive. The name reflects its core design principle - it allows users to define their own custom markup tags, making it 'extensible' rather than being an extensive set of predefined tags.

JavaScript code is placed inside the `` element in HTML. This element can appear in the head or body section. The other options (<js>, <javascript>, <scripting>) are not valid HTML elements and will not execute JavaScript code.

External scripts are referenced via the src attribute in tags and are never displayed on the page. Browsers that don't understand JavaScript simply ignore the entire <script> element. Comment hiding was only needed for inline scripts to prevent code from displaying as text content, not for external script files.

When JavaScript is disabled in the browser, no JavaScript code can execute, including event handlers. This is typically a browser setting that users can configure. The presence of stylesheets, local execution, or other events being processed does not prevent JavaScript execution.

External JavaScript files (.js) contain only JavaScript code without any HTML tags. The script tag with the src attribute is placed in the HTML document to load the external file. If you include script tags in an external .js file, it would cause JavaScript syntax errors.

HTML (HyperText Markup Language) is the standard markup language for creating and designing web pages. It defines the structure and layout of web content, not mathematical solving, translation, or graph plotting.
