The ISO-OSI Reference Architecture, also known as the OSI model, is a theoretical framework for understanding how communication between different devices on a network works. The OSI model is a layered architecture that defines how information is transmitted between devices on a network. The OSI model consists of seven layers, each with a specific function. In this answer, we will discuss the OSI model in detail.

Physical layer:

The physical layer is the first layer of the OSI model. It is responsible for transmitting raw data between devices on a network. The physical layer deals with the physical characteristics of the communication medium, such as the voltage level, signal timing, and data transmission rate. Examples of physical layer devices include network cables, hubs, and repeaters.
