Bandwidth use refers to the ways of allocating the capacity of
transmission media. The total media capacity or bandwidth can be divided into
channels. A channels is simply a portion of the bandwidth that can be used for
transmitting data. The two ways of allocating the capacity of bounded
transmission media are the following:
(a) Broadband.
(b) Baseband
Base band is a network system in which a single digital signal is
passed over the channel. Whereas Broadband is a network system in which several
analog signals share the same physical network channel.
Baseband
These transmissions use the entire media bandwidth for a single
channel. Baseband is commonly use for digital signalling, although it can also
be used for analog signals. Most Local Area Network (LAN) use baseband
signalling.
Broadband
These transmissions provide the ability to divide the entire media
bandwidth into multiple channels. Since each channel can carry a different
analog signal or digital signal, broadband networks support multiple
simultaneous conversations over a single transmission media.
