What are the data communication model?
The OSI Reference Model contains seven layers that define the functions of data communications protocols. Each layer of the OSI model represents a function performed when data is transferred between cooperating applications across an intervening network.
What are the basics of data communication?
Communication is all about sharing information, local or remote. Specifically, data communication is the exchange of data between two devices (part of the communication system made up of hardware/physical equipment and software/program) via a transmission medium such as a wire cable or air/water (wireless).
What is the basic model of communication?
Communication is the exchange of messages between a sender and a receiver via a medium. This is the basic communication model. The receiver’s response or feedback is part of the model and consideration of the context(s) in which communication takes place is also important.
What are the 5 basic components of data communication?
The five components are :
- Message – It is the information to be communicated.
- Sender – It is the device which sends the data messages.
- Receiver – It is the device which receives the data messages.
- Transmission Medium – It is the physical path by which a message travels from sender to receiver.
What is data communication draw and explain data communication model?
Data communication refers to the exchange of data between a source and a receiver. Data communication is said to be local if communicating devices are in the same building or a similarly restricted geographical area. He meanings of source and receiver are very simple. The device that transmits the data is known.
What are the basic components of a communication system?
The basic components of a communication system are information source, input transducer, transmitter, communication channel, receiver, output transducer, and destination.
What is data communication explain?
Communication is an act of sending or receiving data. Thus, data communication refers to the exchange of data between two or more networked or connected devices. These devices must be capable of sending and receiving data over a communication medium.
What is basic communication model explain it which block with suitable figure?
The block diagram of a communication system will have five blocks, including the information source, transmitter, channel, receiver and destination blocks. The information source converts this information into physical quantity.
What is data communication Short answer?
Data communications are the exchange of data between two devices via some form of transmission medium such as a wire cable. For data communications to occur, the communicating devices must be part of a communication system made up of a combination of hardware (physical equipment) and software (programs).
