5. Guided Media
• In guided media, transmitted data travels through cabling system that has a
fixed path. For example, copper wires, fiber optic wires, etc.
8. Twisted Pair Cable
• A twisted pair cable is a type of cable made by putting two separate
insulated wires together in a twisted pattern and running them parallel
to each other.
• This type of cable is widely used in different kinds of data and voice
infrastructures.
9. Coaxial Cable
• Coaxial cable is used for local area networks and cable
television systems.
• Transmission speed ranges from 200 million bits per second
to more than 500 million bits per second.
10. Coaxial Cable
• Coaxial cable is a type of cable that
has an inner conductor surrounded by
an insulating layer, surrounded by a
conductive shielding.
• Many also have an insulating outer
jacket
• The diagram below illustrates the
construction of a typical cable
11. Fiber Optic Cable
A cable consisting of one or more
thin flexible fibers with a glass core
through which light signals can be
sent with very little loss of strength.
15. Radio Waves
• Radio waves are a type of electromagnetic radiation best-known for their
use in communication technologies, such as television, mobile phones and
radios. These devices receive radio waves and convert them to mechanical
vibrations in the speaker to create sound waves
17. Infra-red
• Infrared transmission systems are widely used for short-
range communications. A common application for infrared is in remote
control systems for televisions, VCRs, DVD players and set-top boxes of
various descriptions
18. Bluetooth
• Bluetooth technology is a short-range
wireless communications technology to replace the cables connecting
electronic devices, allowing a person to have a phone conversation via a
headset, use a wireless mouse and synchronize information from a mobile
phone to a PC, all using the same core system
19. Satellite
• A communications satellite is an artificial satellite that relays and
amplifies radio telecommunications signals via a transponder; it creates
a communication channel between a source transmitter and a receiver at
different locations on Earth
