Assignment 1: The Benefits of Twisted Pair Cable The first thing that should be done in this case is to add a server to the network and make the change from a Peer-to-Peer network to a Client/Server network. This give the company a lot more control over what is available to the various users and can help to mitigate risk to sensitive data and other data that does not need to be shared with the entire company. Additionally‚ this eliminates the need for users to remember multiple username/password

The use of shielded cables in security systems provides some protection from power frequency and radio frequency interference‚ reducing the number of false alarms being generated. The best practice is to keep data or signal cables physically separated by at least 3 inches (75mm) from ’heavy’ power circuits which are in
