What is data communication with example?

Communication is the process of sharing a message. A conversation between two people is an example of communication. Data communications refers to the sharing of a virtual message. Electronic communications, like emails and instant messages, as well as phone calls are examples of data communications.

What is message in data communication?

Message: The message is the transmission (data) to be communicated. It can consist of text, number, pictures, sound, or video or any combination of these. Protocol: A protocol is a set of rules that governs data communication. It represents an agreement between the communicating devices.

What are the different types of data communication?

There are two methods used to transmit data between digital devices: serial transmission and parallel transmission. Serial data transmission sends data bits one after another over a single channel. Parallel data transmission sends multiple data bits at the same time over multiple channels.

What are the 3 data communication?

There are three modes of transmission, namely: simplex, half duplex, and full duplex.

What is delivery in data communication?

Delivery. The system must deliver data to the correct destination. … Data delivered late are useless. In the case of video and audio, timely delivery means delivering data as they are produced, in the same order that they are produced, and without significant delay. This kind of delivery is called real-time transmission.

What are the 4 basic elements of communication?

The communication process is made up of four key components. Those components include encoding, medium of transmission, decoding, and feedback. There are also two other factors in the process, and those two factors are present in the form of the sender and the receiver.

What are the 5 components of a network?
