Multiplexing: FDM, WDM and TDM

Multiplexing is a scheme that sends multiple signals or stream of information in the forms of analog data or digital data over a single physical trunk (also called as transmission lines /circuits/ channels).
These multiplexing scheme can be divided into two basic categories: FDM ( Frequency Division Multiplexing) and TDM (Time Division Multiplexing ).

RS-232-C Interface standard

In the early 1960’s, a standard committee, known as Electronic Industries Association (EIA) developed a common interface standard for data communications equipment between the terminal or computer and the modem using serial binary data exchange. In the standards, the terminal or computer is officially called a DTE (Data Terminal Equipment) and the modem is officially called a DCE (Data Circuit-Terminating Equipment). This interface is also known as EIA-232 or EIA-RS-232 standards.
