What is data communication in a computer network?

Data Communication is a process of exchanging data or information. In case of computer networks this exchange is done between two devices over a transmission medium. This process involves a communication system which is made up of hardware and software.

What are the 3 data communication?

Data communication between different devices are broadly categorised into 3 types: Simplex communication, Half- duplex communication, and Full-duplex communication. It is a one way or unidirectional communication between two devices in which one device is sender and other one is receiver.

What are three main components of a data communication system?

There are three broad categories of communications system components: (1) transmission media, (2) hardware, and (3) software.

What are the five requirements for a data communication system?

What is data communication with example?

For example, a common example of data communications is a computer connected to the Internet via a Wi-Fi connection, which uses a wireless medium to send and receive data from one or more remote servers.

What is the best mode for data communication?

Full duplex: Using a telephone, both speakers can communicate at the same time. The full duplex transmission mode offers the best performance among the three, on account of the fact that it maximises the amount of bandwidth available.

What are the two types of line configuration?

Line Configuration in Computer Networks

  • Point-to-Point Connection.
  • Multipoint Connection.

What are the two types of networking?

Two basic network types are local-area networks (LANs) and wide-area networks (WANs).

What are the key components of data network?

Networks are comprised of four basic elements: hardware, software, protocols and the connection medium. All data networks are comprised of these elements, and cannot function without them.
