The OSI model consists of seven layers, as follows (working from the bottom up):
Physical layer: This is the layer where the network hardware operates. Rules for this layer govern the
types of connectors used, what types of signaling techniques carry data across the network, and the
types of cable or other networking media that the physical, tangible part of the network uses. In some
sense, this is the only part of the OSI model that you can see and touch.
Data Link layer: This layer handles communication with the network hardware. For outbound
messages, the Data Link layer enables the conversion of the bits that computers use to represent data
into equivalent signals needed to move data across the network. For inbound messages, it reverses
the process by enabling the conversion of signals...
