explain block diagram of communication system, explain osi model

Question

Accepted Answer

A communication system consists of various components that work together to transmit and receive information. The OSI model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven layers.

A communication system typically consists of a transmitter, receiver, channel, and noise source.
The transmitter processes the input signal and converts it into a form suitable for transmission through the channel.
The receiver then receives the transmitted signal, processes it, and converts it back into the original form.
The channel is the medium through which the signal is transmitted, such as wires, cables, or air.
The OSI model consists of seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
Each layer in the OSI model performs specific functions and communicates with the adjacent layers to ensure the successful transmission of data.
