Explanation

Transmission is the act of transferring something from one spot to another, like a radio or TV broadcast, or a disease going from one person to another. The noun transmission comes from the Latin word transmissio, which means “sending over or across, passage.” The transmission of a message is the delivery of the message. Transmission can also be a communication sent out by radio or television, while the transmission of a disease is the passing of that virus or bacteria between people. A vehicle’s transmission is the part of the engine that uses the energy created by the burning fuel to make the axle turn.
