OSI Model Layer 1 Physical

This lesson covers the physical layer of the OSI model (Layer 1). This first layer consists of everything from cables and bits, to electrical impulses and wireless data travelling back and forth. This is the layer where data is converted to signals and vice versa. Also included in the physical layer are pinouts, voltages and cable specifications.
