An optical communication system is any form of communications system that uses light as the transmission medium. Equipment consists of a transmitter, which encodes a message into an optical signal, a communication channel, which carries the signal to its destination, and a receiver, which reproduces the message from the received optical signal.
Many models of communication include the idea that a sender encodes a message and uses a channel to transmit it to a receiver. Noise may distort the message along the way. The receiver then decodes the message and gives some form of feedback. [1] Models of communication simplify or represent the process of communication.

For these purposes, culture is a shared system of symbols, beliefs, attitudes, values, expectations, and norms of behaviour. [3]
Communication physics aims to study and explain how a communication system works. This can be applied in a hard science way via Computer Communication or in the way of how people communicate. [1] An example of communication physics is how computers can transmit and receive data through networks.
Communication as defined by Merriam Webster Dictionary, [14] is a process by which information is exchanged between individuals through a common system of symbols, signs of behavior. On the other hand, management is the act of getting people together to accomplish desired goals and objectives using available resources efficiently and ...
