This Concept Map, created with IHMC CmapTools, has information related to: Chp4, Transmission Media ???? Satellites, Transmission Media Radio a network that uses electromagnetic radio waves is said to operate at radio frequency, and the transmissions are referred to as RF transmissions., Conventional computer networks use wires as the primary medium to connect computers because wire is inexpensive and easy to install. three basic wiring types -Unshielded twisted pair (UTP) -Coaxial Cable -Shielded Twisted Pair (STP), Transmission Media basics all computer communication involves encoding data in form of energy, and sending the energy across a transmission medium., Satellites ???? contains a transponder that consists of a radio receiver and transmitter., -Unshielded twisted pair (UTP) -Coaxial Cable -Shielded Twisted Pair (STP) Coaxial Cable a coaxial cable consists of a single wire surrounded by a heavier metal shield., Satellites Low Earth Orbit Satellites they orbit a few hundred miles above the earth (typically 200 to 400 miles), networks also use flexible glass fibers to transmit data. Glass fibers Transmission Media, Transmission Media ???? Copper Wires, networks also use flexible glass fibers to transmit data. like Optical fiber which is medium uses light to transdort data, Conventional computer networks use wires as the primary medium to connect computers because wire is inexpensive and easy to install. ???? Copper Wires, Satellites Geosynchronous Satellites are placed in an orbit that is exactly synchronized with the rotation of the earth., Infrared ???? is limited to a small area, and usually requires that the transmitted be pointed toward the receiver, -Unshielded twisted pair (UTP) -Coaxial Cable -Shielded Twisted Pair (STP) Shielded twisted pair consists of a pair of wires surrounded by a metal shield., -Unshielded twisted pair (UTP) -Coaxial Cable -Shielded Twisted Pair (STP) Unshielded twisted pair -are called so because they are coated with insulating material, Transmission Media ???? Infrared
