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

same bus. The star topology is a computer network connected via cables to a central system called a hub or switch there are no direct connections between any of the computers‚ although multiple hubs or switches can be added to increase the number of computers that may be connected to the network. A bus topology is the minimum complex network configuration it creates use of a single transmission medium called a coaxial cable. The star topology consists of shielded twisted pair wire (STP)

Silaba Mpasu Physical Networking Unit 6 Exercise 1 Connector Installations Twisted-pair cable On a TWISTED PAIR CABLE I chose to install an RJ-45. This is the standard Ethernet connector for most systems used today. I would first measure out the length of cable that I would need. I would then use a wire cutter to cut the length that I need‚ leaving enough room for corrections and to open the wire. I would then use wire strippers to remove a small piece of the outer most jacket. I would then choose

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

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
