Osi Model Questions
The purpose of the Physical layer in the OSI Model is to establish and maintain the physical connection between network devices. It is responsible for transmitting raw bit streams over a physical medium, such as copper wires or fiber optic cables, and converting them into signals that can be understood by the receiving device. The Physical layer also defines the electrical, mechanical, and procedural specifications for the physical connection, including the type of cables, connectors, and signaling methods to be used.
