Transmission Modes in Computer Networks ( tentxa layer network )

Transmission Modes in Computer Networks

Transmission mode means transferring of data between two devices. It is also called communication mode. These modes direct the direction of flow of information. There are three types of transmission mode. They are :

Simplex Mode
Half duplex Mode
Full duplex Mode

SIMPLEX Mode

In this type of transmission mode data can be sent only through one direction i.e. communication is unidirectional. We cannot send a message back to the sender. Unidirectional communication is done in Simplex Systems.

Examples of simplex Mode is loudspeaker, television broadcasting, television and remote, keyboard and monitor etc.

Simplex Transmission Mode in Computer Networks

HALF DUPLEX Mode

In half duplex system we can send data in both directions but it is done one at a time that is when the sender is sending the data then at that time we can’t send the sender our message. The data is sent in one direction.

Example of half duplex is a walkie- talkie in which message is sent one at a time and messages are sent in both the directions.

Half Duplex Transmission Mode in Computer Networks

FULL DUPLEX Mode

In full duplex system we can send data in both directions as it is bidirectional. Data can be sent in both directions simultaneously. We can send as well as we receive the data.

Example of Full Duplex is a Telephone Network in which there is communication between two persons by a telephone line, through which both can talk and listen at the same time.

Full Duplex Transmission Mode in Computer Networks

In full duplex system there can be two lines one for sending the data and the other for receiving data.

Tentxa layer Network ( Connection Oriented and Connectionless Services )

Connection Oriented and Connectionless Services These are the two services given by the layers to layers above them. These services are : Connection Oriented Service Connectionless Services Connection Oriented Services There is a sequence of operation to be followed by the users of connection oriented service. These are : Connection is established Information is sent Connection is released In connection oriented service we have to establish a connection before starting the communication. When connection is established we send the message or the information and then we release the connection. Connection oriented service is more reliable than connectionless service. We can send the message in connection oriented service if there is an error at the receivers end. Example of connection oriented is TCP (Transmission Control Protocol) protocol. Connection Less Services It is similar to the postal services, as it carries the full address where the message (letter) i...

Tentxa Layer Network ( Comparison of OSI Reference Model and TCP/IP Reference Model )

Comparison of OSI Reference Model and TCP/IP Reference Model Following are some major differences between OSI Reference Model and TCP/IP Reference Model, with diagrammatic comparison below. OSI(Open System Interconnection) TCP/IP(Transmission Control Protocol / Internet Protocol) 1. OSI is a generic, protocol independent standard, acting as a communication gateway between the network and end user. 1. TCP/IP model is based on standard protocols around which the Internet has developed. It is a communication protocol, which allows connection of hosts over a network. 2. In OSI model the transport layer guarantees the delivery of packets. 2. In TCP/IP model the transport layer does not guarantees delivery of packets. Still the TCP/IP model is more reliable. 3. Follows vertical approach. 3. Follows horizontal approach. 4. OSI model has a separate Presentation layer and Session layer. 4. TCP/IP does not have a separate Presentation layer or Session layer. 5. OSI is a reference mode...
