Osi Model Questions Medium
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, fiber optic cables, or wireless signals. The Physical layer defines the electrical, mechanical, and procedural specifications for activating, maintaining, and deactivating the physical link between devices. It also handles the conversion of digital data into a format suitable for transmission over the physical medium and vice versa. In summary, the Physical layer ensures the reliable transmission of data across the physical network infrastructure.
