The purpose of the OSI Physical Layer is to define the electrical, mechanical and functional characteristics of the cabling and signaling used to create physical connections between devices on a network. It also defines the media access methods and the physical topology of the network.
The OSI (Open Systems Interconnection) physical layer is responsible for transmitting raw bits over a physical medium such as copper, fiber, or wireless. It is responsible for the transmission of data between two directly connected nodes and is responsible for providing the physical connection between the two systems. This layer also defines the electrical, mechanical, procedural, and functional specifications for activating, maintaining and deactivating the physical link. It is also responsible for the encoding and decoding of data into signals for transmission.
