             There are various factors that must be considered while transmitting data.

               Example :- Text message , Image , Audio or Video message etc.


Signaling Techniques :-

   Data can be transmitted using either Baseband or Broadband signaling technique.

• Baseband Signals :- Baseband signaling is a technique which uses a signals frequency to transmit data over a cable or wireless path. Base-band signals transmit for data transmission. 

• Broadbrand Signals :- Broadband signals is a technique in which data is transmitted using more than one frequency along a single cable or wireless path. Mostly,broadband signaling make use of analog signals and use frequency division multiplexing (FDM) to create the separate channels.
