a type of wiring in which two conductors of a single circuit are twisted together for the purposes of canceling outelectromagnetic interference (EMI) from external sources; for instance‚ electromagnetic radiation from unshielded twisted pair (UTP) cables‚ and crosstalk between neighboring pairs. It was invented by Alexander Graham Bell. Advantages and Disadvantages: Advantages -Twisted pair cabling is a type of wiring where two conductors are twisted together in order to cancel out electromagnetic

Loop Design * Cable – it is an assembly of conductor in protective coverage sheet arranged so that the connection can be used singly or a combination of it. * Underground cable - it is a cable install beneath the surface of the earth inside a conduit but in such a manner that it can be removed without disturbing the earth surface. * Aerial cable – it is a cable suspended on poles or other overhead structure. * Distribution cable – it refers to an aerial subscriber cable extending away

them. (2) A cable containing multiple pairs of UTP wire. Each wire pair is twisted many times per foot (higher grade UTP cable can have more than 20 twists per foot). The twists serve to cancel out electromagnetic interference that the trans-mission of electrical signal through the pairs generates. An unshielded jacket made of some type of plastic

In cabling you have a coaxial cable‚ optical cable and a twisted pair cable. Coaxial cable is mostly used on computers out of the three. Coaxial was used in the 1980’s and early 90’s‚ however they started using it again with broad band and also is used for connecting a dish from a TV to the roof. The data transfer rate of the coaxial cable is 100 Mbps (Megabits per second). Coaxial and twisted pair uses copper cables to transfer their data however Fibre optic cable uses light to transmit the data

Use your textbook and Internet research to support your answer. Hospitals‚ security systems‚ PA & recording studios. The drawback of STP cables is that they will increase the total cost of an installation. STP cables are more expensive due to the shielding‚ which is an additional material that goes into every meter of the cable. The shielding also makes the cable heavier and stiffer. Thus‚ it is more difficult to handle. 4.1.4 Complete the entries in Table 4- 1. Use your textbook and Internet research

becomes the first provider in a marketplace and has a tremendous cost advantage over other actual and prospective competitors. Natural Monopolies are companies that provide a service to an area. It increases the setup costs‚ it lays all the required cables‚ and it procures the hardware and software that’s required to operate such an enterprise. Companies hire groups of personnel from numerous industries to keep the service running. Nevertheless‚ it is not the establishment that is a natural monopoly
