Answer: B - Time Division Multiplexing is the media access method where devices are assigned a time slot where they will have exclusive access to transmit data, though only during that period of time.

Key Takeaway: TDM is one of two media access methods that use multiplexing which is a central device that combines signals from multiple devices and transmits the combined signal across the medium. The other is FDM, or Frequency Division Multiplexing. TDM will use specified time slots designated for each device to use and FDM will allocate a specific frequency, or channel for each device. TDM will combine multiple baseband (digital) signals, whereas FDM will combine multiple broadband (analog) signals.
