Question 14

True or False? PageRank is an algorithm used by Google Search to rank websites in their search engine results. PageRank was named after Larry Page, one of the founders of Google. PageRank is a way of measuring the importance of website pages. According to Google: PageRank works by counting the number and quality of links to a page to determine a rough estimate of how important the website is. The underlying assumption is that more important websites are likely to receive more links from other websites

Answer 15

False. PageRank is not the only algorithm used by Google to order search engine results, but it is the first algorithm that was used by the company, and it is the best-known. (See (External Link) .)

Answer 12

False. The prototype for the Google search engine was developed by Sergy Brin and Lawrence Page at Stanford. (See The Anatomy of a Large-Scale Hypertextual Web Search Engine .) Apparently that prototype search engine was known as "Backrub".

True. (See (External Link) .)

Go back to Question 11

Answer 10

False. When a person performs an online search, the search engine scours its corpus of billions of documents, (which was created earlier by crawling and indexing web sites) and does two things: first, it returns only those results that are relevant or useful to the searcher's query; second, itranks those results according to the popularity of the websites serving the information. It is both relevance and popularity that the process of SearchEngine Optimization is meant to influence. (See (External Link) .)

Go back to Question 7

Answer 6

False. To cause a webpage to perform better in search engine listings, the most important content should be in HTML text format. Images, Flash files, Java applets, and other non-text content are often ignored or devalued by search engine crawlers. The easiest way to ensure that the words and phrases you display to your visitors are visible to search engines is to place them in the HTML text on the page. (See (External Link) .)

Go back to Question 6

Answer 5

False. Despite the use of the terms "allow" and "disallow", the robots exclusion standard is purely advisory. It relies on the cooperation of the web robot, so that marking an area of a site "out of bounds" with robots.txt does not guarantee exclusion of all web robots. (See (External Link) .)

Answer 4

True. (See (External Link) .)

Go back to Question 4

Answer 3

False. Not all robots cooperate with the standard including email harvesters, spambots and malware robots that scan for security vulnerabilities. (See (External Link) .)

Answer 2

True. (See (External Link) .)

Go back to Question 2

Answer 1

False. The robots exclusion standard , also known as the robots exclusion protocol or robots.txt protocol , is a standard used by websites to communicate with web crawlers and other web robots. (See (External Link) )

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
