#Multiplexing_Vs_Multiple_Access:
Multiplexing:
Multiplexing is the set of techniques that allows the simultaneous transmission of multiple signals across a single data link.
Multiple Access:
If the physical links are shared by more than two nodes/users, it is said to be Multiple Access.
Categories of Multiplexing:
a. Frequency Division Multiplexing (FDM).
b. Time Division Multiplexing (TDM).
c. Wave Division Multiplexing (WDM).
Categories of Multiple Access Methods:
a.Frequency Division Multiple Access (FDMA) - flexible and simple.
b.Time Division Multiple Access (TDMA) - popular.
c.Code Division Multiple Access (CDMA Spread Spectrum) - highly secure.
