Modes of Data Transmission

Data transmission refers to the process of sending digital or analog data from one device to another. There are several modes of data transmission, which are as follows:

1. Simplex: In simplex mode, data transmission occurs in only one direction. That is, the sender can only send data, and the receiver can only receive data. Examples of simplex transmission include radio and television broadcasting.

2. Duplex: In duplex mode, data transmission occurs in both directions simultaneously. That is, the sender can send data, and the receiver can also send data at the same time. Examples of duplex transmission include telephone conversations and video conferencing.

3. Half Duplex: In half-duplex mode, data transmission occurs in both directions, but not at the same time. That is, the sender can send data, and the receiver can receive data, and vice versa. However, only one device can transmit data at a time. Examples of half-duplex transmission include walkie-talkies and CB radios.

4. Semi Duplex: Semi-duplex mode is similar to half-duplex mode, but it allows for higher data transmission rates. In semi-duplex mode, both devices can send and receive data, but not at the same time. However, unlike half-duplex mode, both devices can transmit data simultaneously, but in different directions. Examples of semi-duplex transmission include Ethernet and Token Ring LANs.

Answer Explanation:

Therefore, option C, Semi-Duplex is not a mode of data transmission.

Semi duplex is not a type
