• The development of the TCP/IP protocols in the 1970s made it possible to expand the size of the network, which now had become a network of networks.

The Correct answer is Simplex.

Key Points

• Full Duplex:

• ​It is the mode of transmission that is used in computing networks when there is simultaneous information flow in both directions, from sender to receiver.

• In this mode of transmission, the channel capacity is shared between the two devices.

• The Full Duplex mode features two simplex channels. One channel has traffic flowing in one direction, while the other channel has traffic flowing in the other way.

• The full duplex mode is used when communication in both directions is required.

• Examples: A telephone network and In a messaging app.

• Simplex:

• The Simplex transmission mode is used in computing networks when there is a single or one-way flow of information from sender to receiver

• In this mode of transmission, communication occurs only in one direction,

• A basic example of a simplex transmission mode is communication between a computer and a keyboard and The radio station is a simplex channel.

​

• Half Duplex;
• The half-duplex mode of transmission is used in computer networks when there is a way to flow information from sender to receiver but only one at a time.
• In this mode, the connected devices can transmit or receive the data but not simultaneously.
• The half-duplex mode is used when communication in both directions is not required at the same time.

​

• Examples; Walkie-talkie
• The parallel transmission
• It defines a transmission structure that shares multiple data bits at a similar time over separate media. In general, parallel transmission can be used with a wired channel that uses multiple, separate wires.

Additional Information

• Transmission mode, also known as a communication mode, is the transfer of data between two devices via a communication channel that includes an optical fiber, wireless channels, copper wires, and other storage media.
• The Physical Layer in the Open System Interconnection (OSI) Layer Model is dedicated to data transmission in the network.
• The data transmission method was initially used in modems in a computer networking system in the 1940s1940s, then in LANs, WANs, repeaters, and other networking systems.
• Based on the direction of the exchange of information. The transmission mode is classified into three types: simplex, half duplex, and full duplex.
