Which OSI layer determines the transmission data rate?
The transmission data rate, which refers to the speed at which data is transferred over a network, is governed by the Physical layer of the OSI model. This layer is responsible for defining the electrical, optical, and mechanical properties of the network connections, including the transmission rate. It sets the specifications for the hardware involved in data transmission, such as cables, switches, and connectors, ensuring efficient and reliable communication between devices. 📈🔌
