If you're talking about electronic communication, both analog and digital communication use a "carrier" frequency to send data. Voice can be across a wire without a carrier, but it's not very efficient. When a carrier frequency is used, the baseline frequency or amplitude can be modulated to transmit the data. In the case of a digital signal, the computer is watching the pulses. any anomaly in the pulses that are expected at a specific time can be converted to data. Data is validated using checksums and parity.

What is the advantages of multiplexing?
Because, the higher the data rate, the more cost effective the transmission facility. That is, for a given application and over a given distance, the cost per kbps decline with an increase in the data rate of the transmission facility.
What is the industrial frequency?
Industrial frequency, as used in Communications, aka the ISM band, is the frequency of signals between 900Mhz to around 2.4Ghz of encoded, compressed, or analog signals... industrial frequency can also refer to the common local power grid frequency (usually 60 or 50 Hz)
Rules that govern the orderly transfer of date within data communications?

Definition of broadband?
Broadband refers to telecommunication that provides multiple channels of data over a single communications medium, typically using some form of frequency or wave division multiplexing.
