1.4.4 Broadband and Base band Transmission
Broadband Internet access often shortened to just “broadband”, is high speed Internet access—typically contrasted with dial-up access over modem. Dial-up modems are generally capable of a maximum bit rates of 56 Kbit/s (Kilobits per second) and require the full use of a telephone line whereas broadband technologies supply at least double this speed generally without disrupting telephone use. In contrast Base band allows only one signal at a time.
Most communication between computers, including the majority of local area networks uses only base band transmission.
