True

Telecommunications is the transmission of voice and video as well as data and usually implies transmitting a longer distance than in a data communication network.

True

The network layer performs the same functions in both the OSI and Internet models and is responsible for routing messages from the source computer to the destination computer.

True

The specification stage of the de jure standardization process consists of developing nomenclature and identifying the problems to be addressed.
