FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -FDM enables single transmission mediums, such as copper cable or fiber optic cable, to be shared by multiple independent signals that are generated by multiple users. This is why FDM is a popular choice to multiplex calls in telephone networks.

Detailed explanation-2: -Wavelength Division Multiplexing, or WDM, is a technique in fiber-optic transmission that uses multiple light wavelengths to send data over the same medium.

Detailed explanation-3: -Multiplexing. Multiplexing is the process of combining two or more information channels into a single transmission medium. There are a number of different standards that can be applied to the process. Many standards are common and are applied by manufacturers and carriers on a world-wide basis.

Detailed explanation-4: -FDM is a physical layer technique that combines and transmits low-bandwidth channels through a high-bandwidth channel, like in a car radio. FDMA, on the other hand, is an access method in the data link layer. FDMA also supports demand assignment in addition to fixed assignment.

Detailed explanation-5: -TDM stands for Time Division Multiplexing. FDM stands for Frequency Division Multiplexing. Signal. TDM works well with both analog as well as digital signals. FDM works only with analog signal.
