ISDN:
http://webopedia.internet.com/TERM/I/ISDN.html
64 and/or 128 kilobits per sec. Usually connected via a serial port like a dial-up modem. Has 2 channels a and b with 64k on each. You can use one for internet and the other for normal phone calls or use both for data and get 128k total. standard serial ports are 115k so you get 128k you might have to buy a after serial port card.

ADSL:
http://webopedia.internet.com/TERM/A/ADSL.html
1.5 to 9 Mbps receiving (like for downloads) and 16 to 640 Kbps sending (like uploading). Used over regular copper phone lines but is done digitally (no connecting phones on this line). Usually a 24h connection type using a modem or router that connects to a network card. New and looks neat.

Cable:
http://webopedia.internet.com/TERM/c/cable_modem.html
seems to be 256 Kbps 2 Mbps. Uses a cable modem that connects to a network card. 24h connection. It works like a lan (local area network) in that your basicly sharing your connection with several people so it can degrade quickly the more people on it. Also because of this people might be able to snoop on your connection since everything is send to everyone on the "node" your on.

T1:

1.544Mbits per second. Has 24 channels of 64k each. Usually used by businesses. You can buy franctional T1. Expensive (I think about $1000 a month in the us). 24h connection

T2:
Don't think this exists.

T3:
http://webopedia.internet.com/TERM/T/T_3_carrier.html
43 Mbps. 672 channels of 64k each. Really fast stuff and usually used as part of the Internet backbone (not sure if that is still true). The big boy ISPs have this stuff (and more). 24h connection.

Bonus:

OC:
http://webopedia.internet.com/TERM/O/OC.html
Fiber optics. 51.8mbps (oc1) to 2.488Gbps (oc48). 24 hour connection. I don't even want to know how much this would cost.
