Practical 4

The document discusses various types of networking cables used to connect devices, including coaxial, twisted pair, and fiber optic cables. Coaxial cables are noted for their ability to transmit RF signals with minimal power loss, while twisted pair cables consist of two insulated copper conductors twisted together. The choice of cable type depends on the network's topology, protocol, and size.

Study the Network Cables


Networking cable is a piece of networking hardware used to connect one network device to other
network devices or to connect two or more computers to share devices such as printers or scanners.
Different types of network cables, such as coaxial cable, optical fiber cable, and twisted pair cables,
are used depending on the network's topology, protocol, and size. The devices can be separated by
a few meters or nearly unlimited distances.

1. Coaxial Network Cable

Coaxial cable is a type of network cable that has an inner conductor surrounded by a tubular
insulating layer, surrounded by a tubular conducting shield. The inner conductor and the outer
shield share a geometric axis. Many coaxial cables have an insulating outer sheath or jacket.
Coaxial cable is used as a transmission line for radio frequency (RF) signals. Its applications
include feedlines connecting radio transmitters and receivers with their antennas, computer
network connections, and digital audio and distributing cable television signals. Coaxial cable
has an obvious advantage over other types of radio transmission line. In a good coaxial cable,
the electromagnetic field carrying the signal exists only in the space between the inner
conductor and the outer conducting shield. For this reason, coaxial cables are allowed to be
installed next to metal objects without power losses that occur in other types of radio
transmission line.

2. Twisted Pair Cable

These are a type of guided media. It was invented by Alexander Graham Bell. Twisted
pair cables have two conductors that are generally made up of copper and each
conductor has insulation. These two conductors are twisted together, thus giving the

name twisted pair cables .
