Question

explain briefly the three primary cable types used for computer networking.

Answer 1

Answer:
Networking cables are used to connectone network device to other network devices or to connect two or more computers
to share printer, scanner etc. Different types of network cables like Coaxial
cable, Optical fiber cable, Twisted Pair cables are used depending on the
network's topology, protocol and size.
Coaxial cable is used as atransmission line for radio frequency signals. Its applications include
feedlines connecting radio transmitters and receivers with their antennas,
computer network (Internet) connections, and distributing cable television
signals. One advantage of coaxial over other types of radio transmission line
is that in an ideal coaxial cable the electromagnetic field carrying the signal
exists only in the space between the inner and outer conductors. This allows
coaxial cable runs to be installed next to metal objects such as gutters
without the power losses that occur in other types of transmission lines.
Coaxial cable also provides protection of the signal from external
electromagnetic interference.
An optical fiber cable is a cablecontaining one or more optical fibers that are used to carry light. The optical
fiber elements are typically individually coated with plastic layers and
contained in a protective tube suitable for the environment where the cable
will be deployed. An optical fiber cable consists of a center glass core
surrounded by several layers of protective material. The outer insulating
jacket is made of Teflon or PVC to prevent interference. It is expensive but
has higher bandwidth and can transmit data over longer distances.
Twisted pair cabling is a form ofwiring in which pairs of wires (the forward and return conductors of a single
circuit) are twisted together for the purposes of canceling out electromagnetic
interference (EMI) from other wire pairs and from external sources. This type
of cable is used for home and corporate Ethernet networks.
