|
Unguided media is physically tangible and guided media is not. |
|
In guided media, the signals propagate over a solid substance while in unguided media the data is sent through the air. |
|
Unguided media contains unshielded twisted pairs while guided media contains shielded twisted pairs. |
Transmission media is classified into two groups: guided media and unguided media. Guided media is the type of transmission media that is physically tangible in which the signals propagate over a solid substance such as a copper wire.
