What is Electronic Communication?

The process of communication is inherent to all human life and includes verbal, nonverbal body language print and electronic processes . all electronic communication systems consist of three basic components: A transmitter, A communication channel medium, and a receiver.

Types of electronic communication

Electronic communication is divided into two types

Data communication


1) data communication: –

The transfer of data between two points is called data communication.

2) telecommunication: –

When the transmission data can take place at long distance by means of towers, satellite, or microwaves system is called tc.

Is the transmission of signs, signals, messages, words, writings, images and sounds or information of any nature by wire, radio, optical or other electromagnetic systems. Example of  the Telecommunication  is mobile

Data communication and its types

What is the data communication

Transfer of data from one point to another over a network

Data communications mean that the transmission of digital data between two or more computers and a computer network. The physical connection between networked computing devices is established using either cable media or wireless media. The best-known computer network is the internet. The purpose of the communication system is to exchange data between two or more than two devices.

We also say that data communication which is sometimes also called computer communication is the transfer of data from one device to another device one is the source and a receiver. Through any cable media or satellite or microwave system.

Characteristics of data communication

The data communication must have major three fundamental characteristics:




1) where delivery means the system must deliver data to the correct destination. Data must be received by the intended device.

2) accuracy mean data delivered inaccurately. This means that data should not be altered during transmission.

3) The timeline means data should be delivered on time. When data in the form of video audio is transfer as they produced at the same time to other location is called real-time transition.

Needs for data communication

The data communication technologies are as important as computer technologies that support each other. Basically it’s very important for proper communication throughout the globe. To days banking and financial firms and much other organization could not survive without data communication. Data communication also plays a very important role in the business sector. The business sector use data communication to communicate with a wide variety of individuals and other personnel.  The education sector also provides distance learning education which fully required data communication. Communication technology tools like electronic mail and text messaging systems, speed up the sending of information within and outside of the organization.

Types of data communication

there are two types of data communication

  • Serial communication
  • Parallel communication

Serial   communication

In telecommunication and computer science, serial communication is the process of sending data one bit at one time, sequentially on a single wire, over a communication channel or computer bus. Serial is a common communication protocol that is used by many devices. Serial communication has become the standard for intercomputer communication. Serial communication is used for all long-haul communication and most computer networks save the costs of cable. Serial communication is a popular means of transmitting data between a computer and a peripheral device such as a programmable instrument or even another computer. It’s also easy to established and no extra devices are used because most of the computers have one or more serial ports.

Parallel communication

Parallel communication is a fast method of communication. In parallel transmission transmit the data across a parallel wire. These parallel wires are flat constituting multiple, smaller cables. Each cable can carry a single bit of information. A parallel cable can carry a group of data at the same time. In telecommunication and computer science, parallel communication is a method of sending several data signals over a communication link at one time.
