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

Study claims customers prefer cable to telecom for triple-play An annual survey conducted by Knowledge Networks/SRI claims that 29% of consumers believe that cable systems would provide the best service and value for the triple-play bundle of video‚ voice and broadband. Satellite was the second choice at 22%‚ followed by local phone companies (21%)‚ ISPs (19%) and electric utility companies (8%). In addition‚ the report indicated that while the average household would be willing to spend an

It is important to test the cables before you install them and after they are installed. Although there are many tools that are used for testing the cables in a network this paper is only going to talk about three. The first one is the multifunction cable scanner‚ they are available for testing both copper and fiber optic cable. One such model is the Hobbes 258898 it can test every pin of almost 20 often used cables from coax to 40 pin ribbon cables. It identifies opens‚ shorts and mis-wires at
