Structured Cabling & Networking
Structured cabling, is a standardized
cabling system designed to carry voice, data and video signals in a
commercial or residential environment. Traditionally, cabling has focused on
unshielded twisted pair cable as used in Ethernet networks.
A computer network is a network that
connects computers and devices in a limited geographical area such as home,
school, computer laboratory, office building, or closely positioned group of
buildings and allows sharing of resources and information among devices
connected to the network.
Computer networks can be used for several
purposes:
Facilitating communications:
Using a network, people can communicate
efficiently and easily via e-mail, instant messaging, chat rooms,
telephone, video telephone calls, and video conferencing.
Sharing hardware:
In a networked environment, each computer on a network can access and use
hardware on the network. Suppose several personal computers on a network each
require the use of a laser printer. If the personal computers and a laser
printer are connected to a
network, each user can then access the laser printer on the network, as they
need it.
Sharing files, data, and
information:
In a network environment, any
authorized user can access data and information stored on other computers on
the network. The capability of providing access to data and information on
shared storage devices is an important feature of many networks.
Sharing software:
Users connected to a network can access
application programs on the network.
Network classification & Connection
method
Computer networks can be classified
according to the hardware and software technology that is used to interconnect
the individual devices in the network,
such as Ethernet, Wireless LAN, Optical
Fiber.
Ethernet uses physical wiring to
connect devices. Frequently deployed devices include hubs, switches, bridges
and/or routers. Twisted pair wire is the most widely used medium for
telecommunication. Twisted-pair wires are ordinary telephone
wires which consist of two insulated copper wires twisted into pairs and are
used for both voice and data transmission. The transmission speed ranges from 2
million bits per second to 100 million bits per second.
Wireless LAN technology is
designed to connect devices without wiring. These devices use radio waves or
infrared signals as a transmission medium.
Optical fiber cable consists of
one or more filaments of glass fiber wrapped in protective layers. It
transmits light which can travel over extended distances without signal
loss. Fiber-optic cables are not affected by electromagnetic radiation.
Transmission speed may reach trillions of bits per second. The transmission
speed of fiber optics is hundreds of times faster than for coaxial cables
and thousands of times faster than for twisted-pair wire.
