How is message transmitted from one computer to the other using layers?

Message transmission between computers is facilitated using the OSI (Open Systems Interconnection) model, which consists of seven layers. Each layer has specific functions and protocols, allowing for modular communication. When a message is sent, it passes through these layers, starting from the application layer down to the physical layer, where it's converted into signals for transmission. Upon reaching the destination, the message ascends through the layers, being reassembled and interpreted at the application layer.
