The model allows transparent communication through equivalent exchange of protocol data units (PDUs) between two parties, through what is known as peer-to-peer networking (also known as peer-to-peer communication). As a result, the OSI reference model has not only become an important piece among professionals and non-professionals alike, but ...
The communication skills required for successful communication are different for source and receiver. For the source, this includes the ability to express oneself or to encode the message in an accessible way. [8] Communication starts with a specific purpose and encoding skills are necessary to express this purpose in the form of a message.
In a network using Open Systems Interconnection (OSI) architecture, the physical signaling sublayer is the portion of the physical layer that [7] [8] interfaces with the data link layer's medium access control (MAC) sublayer, performs symbol encoding, transmission, reception and decoding and, performs galvanic isolation.
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.
One of the earliest models of communication was given by Aristotle. [2] [71] He speaks of communication in his treatise Rhetoric and characterizes it as a techne or an art. [72] His model is primarily concerned with public speaking and is made up of five elements: the speaker, the message, the audience, the occasion, and the effect. [71] [73]
Effective communication in an organization can be a basis for sound decision-making and planning, facilitates smooth and efficient work and coordination in the organization, increases managerial capacity, can be a useful tool for public relations (image building), increases productivity, and others.

It is meant for short-range communication using devices that mimic walkie-talkies. [6] Family Radio Service (FRS) is also meant for short-range communication using devices that mimic walkie-talkies. Like the CB radio, the FRS does not require a license and can be used by anyone who is not a member of a foreign government. [7]
On the ARPANET, the starting point for host-to-host communication in 1969 was the 1822 protocol, written by Bob Kahn, which defined the transmission of messages to an IMP. [10] The Network Control Program (NCP) for the ARPANET, developed by Steve Crocker and other graduate students including Jon Postel and Vint Cerf , was first implemented in ...
