Cable uses fibre, ADSL uses copper
You might be able to get a "cable" connection presented to you as fibre in your area, but I'd think that's extremely rare...
Cable Internet is so-called because it is designed to run over Cable TV networks, and is generally presented to the end user as a coax with a copper conductor. This can of course provide more bandwidth to start off with than a pair of copper wires. ADSL then works by using some fairly clever tricks to get more bandwidth out of the technology it's transmitted over.
For now at least, if you live in a cabled area then you will definately be able to achieve higher speeds from using that, than getting ADSL, even if you do live right next door to the exchange, unless there's an LLU provider at your exchange offering 24Mbit but I should think that'd be a
lot more expensive than 20Mbit cable!
Also, when calculating distance from exchange, remember this is not "as the crow flies", but instead following the route of the cables. This will most likely be the route from the exchange to your house following the major roads.
I Think get 100mbps when i plug the Network (Lan cable) thing into my Laptop that comes out my Talk Talk Modem.
That's the speed of the LAN (Local Area Network) connection betweeen your laptop and your ADSL modem. The modem is then connecting you to the Internet at the speed of your ADSL line, whatever that may be. So sorry to disappoint but no you haven't been the surprise recipient of a super-duper 100Mbit ADSL line
Another thing is mbps related to Mb in any way ?
E.g. 100mbps
and 4mb etc etc
When people talk about a "4 Meg" or "4Mb" or "4 Megabit" connection, that refers to a connection capable of downloading at 4 Megabits per second. Mbps is another way of denoting it. Megabits shouldn't be confused with Megabytes, there are 8 bits in a byte and thus 8 Megabits in a Megabyte.
Thus to give you a real world example, it should in theory take 2 seconds to download a 1 Megabyte file on a "4 Meg" connection. Hope this helps D1CKY :approve:
