What Are Data Communication?

Data communication refers to the exchange of data between a source and a receiver via form of transmission media such as a wire cable.

Data communication is said to be local if communicating devices are in the same building or a similarly restricted geographical area.

What is the definition of data communication?

Data communications (DC) is the process of using computing and communication technologies to transfer data from one place to another, and vice versa. It enables the movement of electronic or digital data between two or more nodes, regardless of geographical location, technological medium or data contents.

What are examples of data communication?

Examples of such channels are copper wires, optical fibers, wireless communication channels, storage media and computer buses. The data are represented as an electromagnetic signal, such as an electrical voltage, radiowave, microwave, or infrared signal.

What are the 5 components of data communication?

The basic components of data communications are as follows:

  • Message.
  • Sender.
  • Receiver.
  • Medium/ communication channel.
  • Encoder and decoder.

What is data communication and its types?

Different Types Of Data Communication Media. Data communication involves transmission of digital of information to different electronic devices through wireless or cabled connections. The two commonly used computer communication media used are bounded and unbounded media.

What is the main purpose of data communication?

The fundamental purpose of data communications is to exchange information between user’s computers, terminals and applications programs. ! In its simplest form data communications takes place between two devices that are directly connected by some form of point-to-point transmission medium.

Why data communication is needed?

The communication i.e. transferring of data and information over significant distances is known as telecommunication. Advantages of computer network are: Data and software of computer can be shared with other computer on the network. Computers on the network can communicate with each other.

What data explain?

Data is distinct pieces of information, usually formatted in a special way. Since the mid-1900s, people have used the word data to mean computer information that is transmitted or stored. Strictly speaking, data is the plural of datum, a single piece of information.

What is the difference between data and information?

Data is raw, unorganized facts that need to be processed. Data can be something simple and seemingly random and useless until it is organized. When data is processed, organized, structured or presented in a given context so as to make it useful, it is called information. Over time “data” has become the plural of datum.

What are the characteristics of data communication?

The effectiveness of a data communications system depends on four fundamental characteristics: delivery,accuracy, timeliness, and jitter. received by the intended device or user and only by that device or user.

What are three major components of a typical data communication system?

List the three main components of a typical data communication system. Sender and receiver devices, Modems or routers, and Communication medium (channel) 3.

What are the types of data flow?

Simplex: data flows in only one direction on the data communication line (medium). Examples are radio and television broadcasts. They go from the TV station to your home television. Half-Duplex: data flows in both directions but only one direction at a time on the data communication line.

What is the components of data communication?

The five components of data communication are:1. Message – It is the information to be communicated. Popular forms of information include text, pictures, audio, video etc.2. Sender – It is the device which sends the data messages.

What is data communication channel?

A communication channel or simply channel refers either to a physical transmission medium such as a wire, or to a logical connection over a multiplexed medium such as a radio channel in telecommunications and computer networking. Communicating data from one location to another requires some form of pathway or medium.
