DSL: Digital Subscriber Line (DSL) is a method for transferring data over regular phone lines and can be used to
connect to the Internet. However, like a cable modem, a DSL circuit is much faster than a regular phone connection,
even though the wires it uses are copper like a typical phone line.
ADSL: Asymmetric DSL (ADSL) allows download speeds of up to about 1.5 megabits (not megabytes) per second, and upload
speeds of 128 kilobits per second.
SDSL: Symmetric Digital Subscriber Line (SDSL) is similar to ADSL, but allows data transfer speeds of 384 Kilobits per
second in both directions. Theoretically, this type of connection allows download speeds of up to 9 megabits per second
and upload speeds of up to 640 kilobits per second.
