I hate that peeps get these confused. Maybe I'm just anal. Modem: accronym for "modulate demodulate". It stands for this because a modem must modulate and demodulate from analog on the outside line to digital on the computer. Bridge: unit that connects two network segments and can also adapt between two different networking mediums. DSL is a good example. **** With DSL you are using a bridge, NOT a modem. DSL = digital subscriber line... it's already digital, there's no "modem" about it! So next time some one says "DSL modem" slap them in the face. It's a "DSL bridge" as it simply adapts RJ11 (phone line) to RJ45 (ethernet), the signal is digital the whole time. k? k.
