The Physical Link Layer provides the much needed medium for communication of data. In other words, how to go about infrastructural support is detailed by the Physical Link Layer. The Physical Link Layer serves to provide the information for placement of real world communication facilities. These communication facilities are the fundamental requirements of the communication process. Many theoretical studies, and conceptual analysis stand proven by studying the implementation of the PPhysical Link Layer. The Layer speaks to us to how to apply the skills related to plugging. The manner in which we should put subtlety to good use vis-a-vis connectors is explained to us. The details of socket connection is stated by the Physical Layer. How to make cable adjustments is narrated. Top to bottom requirements of connection establishment and its orientation is made clear to us. The main focus of the Physical Link Layer is on ensuring the success of the com...
