Exchange, Is like a mini data centre where your calls and broadband is routed through. In this case Sky, they are BT Wholesalers & use BT exchanges. There is a difference, ADSL (Asymmetric Digital Subscriber Line) which is used by the likes of BT, SKY, Pipex etc the list goes on - most of these are BT wholesalers. So they say for example "up to 8MB" the speed of your adsl connection, will depend on how far you are away from the BT exchange if it's next door great, you should get full if not all the 8mb if its 1 mile + then your speed will be dependant on how far away you are.

Now - Virgin Media Use DSL = Digital subscriber line - This means, they do not use Exchanges etc. You have Fibre Optics for the conection, which means, you get faster downloads, more of the speed you pay for etc. If I remember rightly, the green box you may have at the end of your street, the connection from there is copper, where as from the box to the DC is Fibre *I think this is right* where as BT is copper all the way!

My advice, if you are going just on price then you are a fool. Think about the problems this may cause, price isn't everything you know!
