Networking Media;

This chapter deals with the media used to connect devices into the network. OVer here the term media, refers to what we used to connect the networking devices, the cable.

Based on the OSI Model we know that the Pysical Layer is the one responsible for transfering data (text, pictures, audio) between the source and the destination. Data that travels between the source and the destination is represented by the presence of electrical pulse. It represented by an electrical pulse if the media been is used is a wire, copper, or light pulses in in optical fibers.

In today network environment the most popular type of media is a type of cable composed by copper and the type of signal that travels through this copper wire is a electrical signal.

THis chapter instroduces some basic theory of electricity to better understand Networking at the Layer 1 Level (Physical Layer) of the OSI Model.
