Data communication, message, encoder and decoder
Here are explanations for the terms:
Data Communication: The process of transferring data electronically from one location to another through a communication channel. This can be through various mediums like copper wires, fiber optic cables, or wireless networks.
Message: The information or data being transmitted from a sender to a receiver through a communication channel. This can be in the form of text, images, audio, or video.
Encoder: A device or software that converts the original message into a format suitable for transmission over a communication channel. This can include processes like compression, encryption, and formatting to ensure efficient and secure transmission.
Decoder: A device or software that converts the received message back into its original format, reversing the encoding process. This ensures that the received message is identical to the original message sent.
In simple terms:
Data communication is the process of sending and receiving data.
A message is the data being sent.
An encoder prepares the message for transmission.
A decoder reassembles the message back into its original form.
These terms are fundamental to understanding how data is transmitted and received in various communication systems, including computer networks, telecommunication systems, and even human communication.
