Does anybody there to help me to explain the types of Transmission media? Matthew 26-September-2007 07:07:58 PMComments TRANSMISSION MEDIA. In order to carry the data packets from one node to another on a network some sort of media must be employed. The most common types of ...more details www.dmccormick.org/transmissionMedia.htm - 44k - Posted by waqasahmad Signals are usually transmitted over some transmission media that are broadly classified in to two categories:- Guided Media: These are those that provide a conduit from one device to another that include twisted-pair, coaxial cable and fiber-optic cable. A signal traveling along any of these media is directed and is contained by the physical limits of the medium. Twisted-pair and coaxial cable use metallic that accept and transport signals in the form of electrical current. Optical fiber is a glass or plastic cable that accepts and transports signals in the form of light. Unguided Media: This is the wireless media that transport electromagnetic waves without using a physical conductor. Signals are broadcast either through air. This is done through radio communication, satellite communication and cellular telephony. Posted by jaren |
