Network Configuration Model Guidelines and Rubric T’Keyah Swilley 1. IP address is defined as a unique string of characters that identifies each computer using the Internet Protocol to communicate over a network. DNS is a domain name system it associates various information with domain names assigned to each of the participating entities. The importance of both of these is very high on the priority level.

The server is a computer program that manages access to a centralized resource or service in a network. The client is a desktop computer or workstation that is capable of obtaining information and applications from a server.

The desktop PC, connected to the cable modem to be able to access the internet, as well as the firewall being used as an input device to secure date and information across the PC and wireless modem. The printer is used as an output device on the desktop PC, the IP phone is directly connected into the cable modem – that means that if in fact the internet is down so will the IP phone. These are less complicated components but these are the tools and steps to take in order to ensure that Justin will have the proper functionalities of his network....
