The Network Defense Trainer (NDT) is a live-virtual-constructive (LVC) system for implementing sophisticated cyber range environments used to train all types of cyber warriors. In early data networking, the topology for the network backbone was relatively simple: Operations were centralized, so a star topology made the most sense—and, in some cases, this was the only topology the technology would support. D) multiple duplicate devices and paths in a network built so that data can be rerouted if a breakdown occurs. Computer networking depends on the theoretical application and practical implementation of fields like. Question: Chapter 6 Installing A Physical Network 1. Because an internet service provider provides the path for all your internet traffic, it can monitor and log your internet activity. In recent years it has become apparent that fiber-optics are steadily replacing copper wire as an appropriate means of communication signal transmission. it consists of high capacity (bandwidth) circuits that connect the most important or major cities. In both cases, communication is in the form of electromagnetic waves. Creation of NSFNET was an intellectual leap. In a local area network, a _____ only transmits data to the destination node. Network access points (NAPs) and metropolitan area exchanges (MAEs) are hubs where the backbone intersects regional and local networks and where backbone owners connect with one another. When several local area networks (LAN) are being interconnect over a considerable area, the result is a wide area network (WAN), or metropolitan area network (MAN) if it happens to serve the whole city. A backbone network is a network containing a high capacity connectivity infrastructure that forms the main link, or backbone, to the different parts of. They span the long distances between local phone systems as well as providing the backbone for many network systems. disaccharides. Called NSFNET, it was a T1 line that connected 170 smaller networks together and operated at 1. A Tier 1 provider has the "full table" (of Internet routes/prefixes); they can reach any point on the Internet directly or via a(n equal) “peer” (they have a settlement free path to all points on the Internet). A network administrator configures a static route on the edge router of a network to assign a gateway of last resort.
