(A)Twisted Pair
Advantages :
1. Cheaper and far easier to splice.
2. Less susceptible to electrical interference caused by nearby equipment or wires.
3. In turn are less likely to cause interference themselves
.4. Because it is electrically "cleaner", STP wire can carry data at a faster speed.
Disadvantages :
1. STP wire is that it is physically larger and more expensive than twisted pairwire.
2. STP is more difficult to connect to a terminating block.
(B)Coaxial Pair
Advantages :
1. Coaxial cable can support greater cable lengths between network devices than twisted pair cable.
2. Thick coaxial cable has an extra protective plastic cover that help keep moistureaway.
Disadvantages :
1. Thick coaxial is that it does not bend easily and is difficult to install.
(C)Fiber Optic
Advantages :
1. One single mode fiber can replace a metal of time larger and heavier.
2. Multi-mode optical cable has a larger diameter and can be used to carry signalover short distance.
Disadvantages :
1. Fiber optic versus metal cable is that it is difficult to make connections tofiber optic cable.
2. The optical fiber must be highly polished to allow light to pass with little loss.
