Final answer:
The process of combining two data link tracks into one is known as data multiplexing, which is an efficient technique used in telecommunications for better bandwidth utilization.
Step-by-step explanation:
The process of taking two data link tracks and combining the information into one track is known as data multiplexing. This process is commonly used in the field of telecommunications to efficiently use the bandwidth of a communication channel. By multiplexing signals, multiple data streams can be transmitted over a single physical link, which can improve the utilization of network resources. One example of this is Time Division Multiplexing (TDM), where the signal is divided into multiple time slots, each being used to send a data stream from a different channel.
