In this seven-part collection, we’ll spend time looking at each of the OSI variation layers, starting with the Physical layer.

Generally, CCNA leads ask if the OSI layout has any type of sort of practical uses for network supervisors. I made usage of to examine the specific very same factor, as well as additionally I can presently notify you that the reaction is definitely!

Whenever a network gizmo isn’t truly working efficiently, I regularly mention to “start at the physical layer”. The Physical layer is Layer One of the OSI variation, along with this is where fixing should frequently start.
