014.01.28.2. Can you explain the role of the physical layer in establishing communication between computers on an Ethernet network? How does it serve as an interface between the hardware and the network layers?
When communication is there between two computers, there needs to be a physical layer on which the network layer i.e. internet will function. It serves as an interface b/w hardware and network layer as physical interface is unique in each network host, and through it, the network can differentiate between several hosts.
The physical layer plays a crucial role in establishing communication between computers on an Ethernet network. It serves as an interface between the hardware and the Internet layer. This physical layer acts as a unique physical interface for each network host. Through this interface, the network can distinguish and communicate with various hosts, enabling the differentiation between them during network interactions.
