The Bit Torrent system is a download mechanism, in which you download from others who have already downloaded the same file (peers), instead of straining one download server.
How it works:
– You download a .torrent file (mostly from the tracker itself), which has some info and a link to the tracker server.
– The tracker server.. well, tracks each and every peer; the people who are downloading or have downloaded. Your torrent program connects to this server and requests a list of peers.
– Your program then connects to the peers which have already downloaded parts of the file, which you still have to get. Most programs connect to a dozen peers at the time.
– You then keep repeating to download little parts from others, and others download from you, until you have a complete file.This mechanism keeps the bandwidth down for the servers, and still allows distribution of files.
However, Torrents have become very popular with software/media pirates, because the file itself will never be located on a central server, instead, it will be split over hundreds of computers. This means you can’t tackle it easily by shutting down one server, and because the tracker doesn’t have a physical copy of the file itself, its not doing anything illegal.

“The Wikipedia internal “
The 10 facts about wiki .
1. Articles
There are a massive 17 million articles on Wikipedia, with the number increasing everyday.
2. Languages
There are 262 different language versions of the website, although the English, German and French versions have the most articles.
3. English
Of the 17 million articles, 3.5 million of them are written in the English language.
4. Record breaker
On 9 September 2007, the English version of Wikipedia surpassed two million articles. It made it the largest encyclopaedia ever put together and took the record from the Yongle encyclopaedia, which had held it for 600 years.
5. Readership
Wikipedia claims to have roughly 325 million readers, meaning there are 21 users to every article on the website.
6. Edits
There have to date been over one billion edits on Wikipedia, again with the number growing all the time – and being positively encouraged by founder Jimmy Wales.
7. Wiki
The word “wiki” is the Hawain word for “quick” but now has its own definition as “a web application that allows anyone visiting a website to edit content on it.”
8. Person becomes people
In 2006 the users of Wikipedia who edited the site were named as Time Magazine’s Person of the Year.
9. Hosted state
The servers for Wikipedia are hosted in Florida, therefore content on the site is subject to the US state’s laws.
10. Google gives it a hit
Many of us may go straight to Wikiepdia.org, however 50 per cent of the website’s traffic actually comes from Google.
Do you know about ” i’am feeling lucky ” button on google home page ?
I am feeling lucky button actually makes google lose their money
The “I’m feeling lucky” button allows users to be taken directly to the first search result, which means the user completely skips all other search engine results and pages.
How could this lose them money? According to statistics around 1% of all searches done on Google use this button, completely skipping all possible advertising.
This results in the company losing around $110 million dollars in potential profits!
So why does the company keep an option that looses them a massive amount of profit?
Simply because people like it and it keeps them coming back! Recently, however, Google featured their Nexus 7 tablet on their homepage, making it the first time any advertising has been featured on their homepage.

How many servers they need ???
In 2009 it was reported Google was planning to have ten million servers and an exabyte of information. It’s almost certain that point has been passed, particularly given the volume of data being uploaded to YouTube which alone has 72 hours worth of video uploaded every minute.
Facebook is struggling with similar growth and it’s reported that the social media service is having to rewrite its database. Last year it was reported Facebook users were uploading six billion photos a month and at the time of the float on the US stock market the company claimed to have over a 100 petabytes of photos and video.
Microsoft
Microsoft says that Hotmail has over a billion mailboxes and “hundreds of petabytes of data”.

how many cameras are there to shoot one live match …. ?
The production will be among the most sophisticated ever too, with 28 cameras, including seven ultra-motion cameras, Spidercam as well as graphics with key analytics, all of which will take the viewer right to the heart of the action.
In recent times , technology powerhouse YouTube, partnered with the Indian Premier League to live stream the 2010 IPL series via YouTube. While the IPL series was predominantly broadcast via television, the live stream footage reached 50 million views globally across 200 plus countries. The biggest viewer population was unsurprisingly India. However the United States were surprisingly the second largest audience, a country not known to give much attention to cricket
With the advance of technology, the media have also changed how the game is televised, introducing new ways for the viewer to see the game including video replays, Stump Cam, HawkEye, video umpire and also infrared HotSpot to see where the ball hit the bat.
