What part of the physical layer connects to the MAC sublayer?
The physical layer of the OSI model is responsible for transmitting raw bit streams over a physical medium. To ensure proper communication, it must interface with the Media Access Control (MAC) sublayer, which handles data framing and access control. The portion of the physical layer that directly interfaces with the MAC sublayer is known as the Physical Signalling Sublayer. 🌐🔗 This sublayer manages the electrical, optical, or radio signals used to transmit data, ensuring that the data frames are correctly encoded and decoded for transmission across the network. 📡💡
