Guest network They define exactly how data is exchanged and the expected behavior. A reference model is a conceptual framework for understanding relationships. What is Networking and Communication? Data Communications and Networking Question and Answers . Skip to content. How do standards fit in with regulations at the federal, manufacturing, and organizational levels? Data communications refers to the transmission of this digital data between two or more computers and a computer network or data network is a telecommunications network that allows computers to exchange data. The resources such as printers, file servers, scanners, and internet are easily sharable among computers. The connections of the Computers over a Network are possible through several networking devices like routers, bridges, gateways, cables, Satellites and others. Focus on Test. The IP addresses on this network should be reachable only within the data center and is considered the Management Security Domain. Data communication is said to be local if communicating devices are in the same building or a similarly restricted geographical area. Modern data communication networks are characterized by: ... is the coordinating organization for the US' national system of standards. Introduction . For data communication to occur, the communicating devices must be part of a communication system made up of a combination of hardware and software. Data Communications and Networking is designed to help students understand the basics of data communications and networking, and the protocols used in the Internet in particular by using the protocol layering of the Internet and TCP/IP protocol suite.
