all internet providers track all downloads and up loads and can even trace what web sites up have been on to
all this is done by your i.p address
your i.p address holds info like the area your in and your internet provider and if done right people can even use your i.p address to get into your computer and not only view what you are seeing on your computer screen they can even add virus's and delete file from your computer
(mainly in the system32 file) this is where the main info to your computer is held that file is your main operating system file
ive done it myself by hacking wireless routers in my area
with the right software you can easily enter the computer files on the other computer without them even knowing you are in there computer
going on to viewing sites anonymously
there is a program called i.p hide or something like that which blocks internet sites from seeing your i.p address but alot of sites will not allow you on there sites
you can also check your download and upload speed to see if you are getting what you pay for by going to
www.speedtest.net and click on your local area that is closest
