Mainly used in LAN in which entire capacity of the medium is dedicated to a particular device, Simple and small than broad band.

     Digital communication technology in which (in contrast to 'broadband') the entire bandwidth (data carrying capacity) of a medium such as a wire, cable, or channel, is used to transmit a single signal. Therefore, only one communication channel is available at any given time. Baseband is cheaper and simpler (though less versatile) technology than broadband, and is employed in most types of local area networks such as Ethernet and Token Ring.

     Baseband, data is sent as digital signals through the media as a single channel that uses the entire bandwidth of the media. Baseband communication is bi-directional, which means that the same channel can be used to send and receive signals. In Baseband, frequency-division multiplexing is not possible. (Multiplexing (short muxing) is a process where multiple analog message signals or digital data streams are combined into one signal over a shared medium.)
