Each bit is sent over a separate wire is true for binary synchronous data transmission.

Transmission Modes in Computer Networks. Transmission mode refers to the mechanism of transferring of data between two devices connected over a network. It is also called Communication Mode. These modes direct the direction of flow of information. Data transmission refers to the process of transferring data between two or more digital devices.

In parallel transmission, multiple bits (usually 8 bits or a byte/character) are sent on different channels (wires, channels) simultaneously within the same cable, or radio path, and synchronized to a clock. Parallel devices can transfer data in words of one or more bytes at a time.

The way in which data is transmitted from one place to another is called data transmission mode. It is also called the data communication mode. It indicates the direction of flow of information. Sometimes, data transmission modes are also referred to as directional modes.
