Explanation / Answer

For Local Area Networks (LANs), there are three principal connection schemes: twisted pair, coaxial, and fiber optic cable to physical layer

TP is normally used to carry data at speeds from 10Mbps to 100Mbps, but the speed can be decreased by a number of error characteristics: data loss, crosstalk coupling, and electromagnetic interference (EMI).

Coaxial wire allows for greater shielding from interference and greater segment distances. Coaxial 10base-5/2 has a transmission rate of 10Mbps. 10base-5 has a maximum segment length of about 500m/segment, whereas 10base-2 is about 180m/segment.

Optical fiber is a thin, flexible medium that carries data in the form of light waves through a glass "wire" or cable. This transfer medium works for distances exceeding the 1-kilometer range and is extremely secure (there is no electric signal to tap).
