. While a user is entering and transmitting data, the computer is prevented from sending data to the terminal, which would appear on the terminal screen and cause confusion. For full-duplex transmission, two stations can simultaneously send and receive data from each other. Thus, this mode is known as two-way simultaneous and may be compared to a two-lane, two-way bridge. For computer-to-computer data exchange, this form of transmission is more efficient than half-duplex transmission. With digital signaling, which requires guided transmission, full-duplex operation usually requires two separate transmission paths (e.g., two twisted pairs), while half duplex requires only one. For analog signaling, it depends on frequency: If a station transmits and receives on the same frequency, it must operate in half-duplex mode for wireless transmission, although it may operate in full-duplex mode for guided transmission using two separate transmission lines. If a station transmits on one frequency and receives on another, it may operate in full-duplex mode for wireless transmission and in full-duplex mode with a single line for guided transmission. It is also possible to transmit digital signals simultaneously in both directions on a single transmission line using a signal processing technique called echo cancellation.
