there are certain details of your browser and computer that is available to any website you look at
your ip address, for example, can be used to work out where you are and who your isp is. this can also sometimes tell the site as much detail what town you are in.
the "system" details such as your operating system, browser type and browser version can be used to work out what capabilities you have, in order to show you javascript or flash-enhanced (or even stripped-down) versions of the site - basically, to give you the best possible browsing experience based on what you are looking at the web using
your browser also send details of what link on a page you clicked, and where that took you. tools like the one i use can piece this together to map a path of your visit to the site
all websites have this info available if they want it (it's part of the standard web technologies
tcp/ip and
http) but need to be told to capture this info if they want to do stuff with it
in this instance, i use a free webmasters tool from google called "google analytics" which tracks site visitors... gives you access to all kinds of stuff, should you want it (which quite frankly i dont
