### What are the four basic approaches to multiplexing?

The four basic approaches to multiplexing are Frequency Division Multiplexing (FDM), Wavelength Division Multiplexing (WDM), Time Division Multiplexing (TDM), and Code Division Multiplexing (CDM).

### What is the purpose of multiplexing?

The purpose of multiplexing is to combine information streams from multiple sources for transmission over a shared medium.

### What is Frequency Division Multiplexing (FDM)?

Frequency Division Multiplexing (FDM) is a multiplexing technique that combines multiple signals by assigning each signal a different frequency band.

### What is Wavelength Division Multiplexing (WDM)?

Wavelength Division Multiplexing (WDM) is a multiplexing technique that combines multiple signals by assigning each signal a different wavelength of light.

### What is Time Division Multiplexing (TDM)?

Time Division Multiplexing (TDM) is a multiplexing technique that combines multiple signals by dividing the available transmission time into time slots and assigning each signal a specific time slot.

### What is the difference between Frequency Division Multiplexing (FDM) and Time Division Multiplexing (TDM)?

FDM divides the available bandwidth into frequency channels, while TDM divides the available time into time slots.

### What is the purpose of Statistical Time Division Multiplexing?

The purpose of Statistical Time Division Multiplexing (STDM) is to dynamically allocate bandwidth based on the actual needs of the connected devices.

### What is SONET/SDH?

SONET (Synchronous Optical Network) and SDH (Synchronous Digital Hierarchy) are standardized protocols for transmitting digital signals over optical fibers.

### What is Code Division Multiplexing (CDM)?

Code Division Multiplexing (CDM) is a multiplexing technique that uses different codes to separate multiple signals transmitted over the same frequency channel.

### What is a Digital Carrier system?

A Digital Carrier system is a telecommunications system that transmits digital signals over a network.

Test your knowledge on Multiplexing techniques such as Space Division, Frequency Division, Wavelength Division, Time Division, Statistical Time Division, and Code Division. Explore the characteristics, digital carrier systems, SONET/SDH, and cable modem technologies in this informative quiz.
