What does This Blog Want to Be

It took so long for me to decide to write some articles again in this blog. I just don't know what it wants to be.. may be I just don't know what this blog will be. Well, this letter is my representative to all of my article confuse.

But in the middle of it I just want to share it to you. Perhaps this will be useless tips for you, once again, I just want to write all here..

1. Be eager about something new.. Dig it, and know it well.
2. Consistent about your want. Reach it and make your dream come true.
3. Start it. If you're willing something, just do it, and start with a small step.
4. Start it now...

That is all I want to write right now..

Search Engine

Search Engine, software program that helps users find information stored on a personal computer, or a network of computers, such as the Internet. A user enters search terms, typically by typing a keyword or phrase, and the search engine retrieves a list of World Wide Web (WWW) sites, personal computer files, or documents, either by scanning the content stored on the computers or computer networks being searched or by parsing (analyzing) an index of their stored data.

Search engines are most often used to find pages, files, news, images, and other data on the Web. Some of the most popular Web search engines include Google Inc., Microsoft Network (MSN) Search, and Yahoo! Inc. Each can be accessed from any Web browser, and each can be used for free. (Encarta Encyclopedia is published by the Microsoft Corporation.)
These engines operate by building—and regularly updating—an enormous index of Web pages and files. This is done with the help of a Web crawler, or spider, a kind of automated browser that perpetually trolls the Web, retrieving each page it finds. Pages are then indexed according to the words they contain, with special treatment given to words in titles and other headers. When a user inputs a query, the search engine then scans the index and retrieves a list of pages that seem to best fit what the user is looking for. Search engines often return results in fractions of a second.

Generally, when an engine displays a list of results, pages are ranked according to how many other sites link to those pages. The assumption is that the more useful a site is, the more often other sites will send users to it. Google pioneered this technique in the late 1990s with a technology called PageRank. But this is not the only way of ranking results. Dozens of other criteria are used, and these will vary from engine to engine.

Many times, search results will also include what are called sponsored links, links that are ranked high in the search results or are prominently displayed because third-party companies pay a fee to the search engine. More often than not, sponsored links are labeled as such, but inexperienced Internet users often have trouble distinguishing between sponsored pages and unsponsored results. Sponsored links provide search engines with their primary source of revenue.

How Google Ranks the Page

This is the picture how google or other page rank site ranks the page;
From the picture we can see that:
Page C has a higher PageRank than Page E, even though it has fewer links to it: the link it has is much higher valued. A web surfer who chooses a random link on every page (but with 15% likelihood jumps to a random page on the whole web) is going to be on Page E for 8.1% of the time. (The 15% likelihood of jumping to an arbitrary page corresponds to a damping factor of 85%.) Without damping, all web surfers would eventually end up on Pages A, B, or C, and all other pages would have PageRank zero. Page A is assumed to link to all pages in the web, because it has no outgoing links.
Thats why our blogs has its page rank number.
