![]() This mode is used when communication in both directions is required simultaneously.įor Example, a Telephone Network, in which both the persons can talk and listen to each other simultaneously.įollowing are the advantages of using a full-duplex transmission mode: The capacity of the channel is divided between the two directions of communication. It is two-way communication in which both the stations can transmit and receive the data simultaneously.įull-Duplex mode has double bandwidth as compared to the half-duplex. Delay in transmission may occur as only one way communication can be possible at a time.įull-Duplex is the data transmission mode in which the data can flow in both directions at the same time.The two-way communication can not be established simultaneously at the same time.It facilitates the optimum use of the communication channel.įollowing are the disadvantages of using a half-duplex transmission mode:.In such cases, the data needs to be transmitted again by the receiver.įor Example, Walkie-Talkie, Internet Browsers, etc.įollowing are the advantages of using a half-duplex transmission mode: It can be used for error detection when the sender does not send or the receiver does not receive the data properly. This type of data transmission mode can be used in cases where there is no need for communication in both directions at the same time. Transmission lines can carry data in both directions, but the data can be sent only in one direction at a time. In this type of transmission mode, the entire capacity of the channel can be utilized for each direction. When one device is sending the other can only receive and vice-versa. In other words, each station can both transmit and receive the data but not at the same time. Half-Duplex is the data transmission mode in which the data can flow in both directions but in one direction at a time. There is no mechanism for information to be transmitted back to the sender(No mechanism for acknowledgement).It is unidirectional in nature having no inter-communication between devices.It has the least or no data traffic issues as data flows only in one direction.įollowing are the disadvantages of using a Simplex transmission mode:.It utilizes the full capacity of the communication channel during data transmission.It is similar to a one-way street.įor Example, Radio and TV transmission, keyboard, mouse, etc.įollowing are the advantages of using a Simplex transmission mode: It is mainly used in the business field as in sales that do not require any corresponding reply. This transmission mode is not so popular because we cannot perform two-way communication between the sender and receiver in this mode. Similarly, a receiver can only receive data but can not send it. In this mode, a sender can only send data but can not receive it. Simplex is the data transmission mode in which the data can flow only in one direction, i.e., the communication is unidirectional. According to the Direction of Exchange of Information: 1. Now, let us study these various data transmission modes in the computer network one by one. ![]() ![]() The data transmission modes can be characterized in the following two types based on the number of bits sent simultaneously in the network: The data transmission modes can be characterized in the following two types based on the synchronization between the transmitter and the receiver: The data transmission modes can be characterized in the following three types based on the direction of exchange of information: So, in this blog, we will learn about different data transmission modes based on the direction of exchange, synchronization between the transmitter and receiver, and the number of bits sent simultaneously in a computer network. It mainly decides the direction of data in which the data needs to travel to reach the receiver system or node. In the Open System Interconnection(OSI) Layer Model, the Physical Layer is dedicated to data transmission in the network. It specifies the direction of the flow of information from one place to another in a computer network. It is also called Data Communication or Directional Mode. Data Transmission mode defines the direction of the flow of information between two communication devices. ![]()
