Detailed explanation-1: -The physical layer translates logical communication requests from the into hardware specific operations. Explanation: Physical layer accepts data or information from the data link layer and converts it into hardware specific operations so as to transfer the message through physical cables.
Detailed explanation-2: -The physical layer establishes the connection between a device and a transmission media, such as copper or optical fibre.
Detailed explanation-3: -The physical layer describes the way data is actually transmitted on the network medium. The data link layer defines how these streams of bits are put together into manageable chunks of data. Ethernet is the best known implementation of the physical and data link layers.
