Key Concepts

OSI Model

The OSI model is a conceptual framework that standardizes the functions of a telecommunication or computing system regardless of its underlying structure and technology. It divides the network communication process into seven distinct layers, which helps in understanding and troubleshooting network issues by assigning specific responsibilities to each layer.

Physical Layer

The physical layer is the first layer of the OSI model and is responsible for the transmission and reception of raw bitstreams over a physical medium. This layer handles the conversion of data into electrical, optical, or radio signals that can be transmitted over network hardware, making it a fundamental component in the communication process.
