Internet and Web

A SharePoint site definition provides prepackaged templates that define the structure, lists, libraries, and initial content for new sites. Option A is incorrect - it's not just a collection of sites. Option C is wrong - permissions are managed separately through permission levels, not site definitions.

A SharePoint workspace is a collaborative site where team members can work together on Web pages, lists, and document libraries. It's designed for team collaboration and content sharing. Option B is incorrect - workspaces are not for connecting databases. Option C is wrong - web applications are created at a different level.

Reader, Contributor, and Web Designer are all standard SharePoint roles. Web Creator is not a standard built-in SharePoint role/permission level. The standard roles include Full Control, Designer, Edit, Contribute, Read, etc., but not Web Creator.

HTTP status code 200 OK indicates that a request has succeeded. In contrast, 304 is a redirection code indicating the resource has not been modified and should be loaded from cache, while 404 is a client error showing the resource was not found. Thus, only 200 represents success.

XMLHttpRequest makes asynchronous HTTP requests programmatically from JavaScript. These requests do not affect the browser's history stack - only navigation actions (clicking links, setting window.location, etc.) create history entries. AJAX requests are invisible to the browser's back/forward navigation.

HTTP is stateless because each request-response pair is independent. The server doesn't retain any information about previous requests from the same client. Every request must contain all necessary information for the server to understand and process it. 'Connectionless' is incorrect because HTTP does use TCP connections; 'wireless' and 'freebies' are irrelevant.

Historically, the integrated browser engine in Android (WebView and the default browser prior to Chrome Integration) was built on top of the open-source WebKit layout engine. While Chrome is a browser, the underlying open-source rendering framework originally utilized by Android's browser core was WebKit.

NSURLRequest encapsulates both the URL to load and the policies for how the data should be cached and loaded. It doesn't perform the actual loading (that's NSURLConnection/NSURLSession) nor does it fetch data itself.

The microblogging site Meme (also known as Meme Yahoo) belonged to Yahoo. It was a social networking and microblogging service launched by Yahoo in 2009, allowing users to post short updates, photos, and videos. The service was eventually shut down by Yahoo in 2012 as part of their product restructuring.

SEO (Search Engine Optimization) encompasses techniques to improve webpage rankings on search engines and increase website visibility. Options A, B, and D all describe aspects of SEO - from ranking improvement to visitor attraction to specialized website building processes. Option C describes file transfer protocols (FTP/SFTP), which is unrelated to search engine optimization.

Black hat SEO refers to unethical techniques used to manipulate search engine rankings, such as keyword stuffing, cloaking, and link farming. These methods violate search engine guidelines and can lead to penalties. The statement correctly identifies that these practices are disapproved by search engines.

Search engines use automated programs called crawlers (also known as spiders or bots) to discover and index web pages. These crawlers follow links from page to page, collecting information about each page's content. Affiliate marketing, cost per impression, and cost per action are advertising models, not indexing mechanisms.

Spamdexing is indeed another term for search engine spam. It combines 'spam' and 'indexing' to describe deceptive techniques used to manipulate search engine rankings. Examples include repeating unrelated keywords, hiding text, and creating doorway pages.

AdSense is Google's advertising platform that pays website owners to display ads - it's NOT an SEO technique. Link exchange, social bookmarking, and directory submission are legitimate SEO strategies used to build backlinks and improve search rankings.
