Network+ N10-009 OSI Model

Information Technology9 CardsCreated 12 months ago

The Physical layer, as the lowest layer of the OSI model, handles the transmission and reception of raw bits (0s and 1s) over a physical medium. It defines the electrical, mechanical, and procedural specifications—such as cabling, signal encoding, voltage levels, and transmission modes—for how those bits actually travel between devices.
