Maintain your anonymity over the internet using Tor

Ever feared what your ISP ( or ) a Eavesdropper can know about you looking at your browsing data or listening to your network, well you are not alone, there are many people out there who feel very uneasy, at the thought of there privacy being "violated".

There are many tools that offer anonymity over the internet, but most of them are pretty expensive, and the rest may not be as reliable as you wanted the to be, however there is tool called Tor available for free download at http://www.torproject.org/download.html.en (download tor browser bundle for windows, if you are a windows user )  which uses a technique called onion routing( read Onion Routing Wikipedia Entry for more ) using which your network traffic is encrypted and relayed over several network systems( called relays), the technique is designed in such a way that any particular system will only know its previous system and the next system, thus making it impossible for any system to resolve the path or data of your network

Using tor however comes at a price, it slows down the internet connection speed, although not technically but practically, I mean to say your Internet connection speed remains the same, but since the data has to be encrypted and sent over many relay servers it will take a bit more time than the usual to view the web page.There is also an other issue, since the webpage is requested from a server in different location (it was in Netherlands for me), you may get the webpage that has been modified for that particular location.To explain it better I was expecting to see Google India web page, when i typed Google.com (remember Google redirects you to your country specific page), instead i received a Google Netherlands page.
