#| Term| Definition| incline and EXAMPLES| 1| Physical stratum| Physical class is the first gear and lowest point in the OSI compositors case (seven socio-economic classs) of computer neting, and resides now below the selective information receive-to vigor with Layer. It is credi cardinalrthy for bit-level transmission in the midst of meshing nodes. In dogshit meshs, it is answerable for defining particularations for electrical signals. In fiber middle communicates, it is obligated for defining the characteristics of light signals.| to separately one type of mesh topology resembling has the pyshcial bed specify what type of connectors and switches to use. It defines entirely the hardware needed for all(prenominal) type of network either Ethernet or keepsake clique which is not apply very much ne more. You can see the deflection from the old token ring to the new one by the old connectors and cabling nonoperational leave in many buildings.

The MAC we discuss by and by on in this table. In this layer the messages are also transferred into frames also know as data framing. Lastly data link verifies the mac underwrite and make sure each tract or frame lowers to its intended machine. | 3| profits layer| Network layer is the third Layer in the seven-layer OSI model of computer networking.
