Voice over Internet Protocol is a new way to talk on your phone through your broadband internet connection. A VoIP router is needed to help you use the same phone you have been using before your VoIP connection.
An extranet is an extension of your company's internal network that allows outside users to provide and access information in a secure environment. Like an intranet, it is web browser based, making information available on any computer without any special equipment.
Patch panels are used as the central point in a network where all the network cables terminate. It is the grand central station of the network. Networks that use patch panels (and almost all modern networks use this technology) are consider “star-networks” or they use the term “star-topology.”
Vonage is one of the leading providers of commercial and residential VoIP telephony. In a short span of three years, it has acquired more than a million customers for this recent communications technology. The company is based in Holmdel, New Jersey and offers quality-rich features as a part of its VoIP offering to customers. Customers throughout the United States can avail Vonage services; Vonage started its Canada and UK services in 2004 and 2005, respectively.
As access to the Internet becomes more widespread with faster, more reliable and 'always on' connections becoming the norm the growth of applications using the hosted application model continues to expand.
Computers and storage mechanisms (CD-ROMs, hard drives, USB flash drives, DVD-ROMs, etc.) need to hold much larger values than what a byte can hold (0-255). Thus, the terms kilobyte, megabyte, gigabyte, and terabyte were created to represent such large amounts of information.
The Enhanced Interior Gateway Routing Protocol (EIGRP) represents an evolution from its predecessor IGRP (refer to Chapter 42, "Interior Gateway Routing Protocol"). This evolution resulted from changes in networking and the demands of diverse, large-scale internetworks. EIGRP integrates the capabilities of link-state protocols into distance vector protocols. Additionally, EIGRP contains several important protocols that greatly increase its operational efficiency relative to other routing protocols. One of these protocols is the Diffusing update algorithm (DUAL) developed at SRI International by Dr. J.J. Garcia-Luna-Aceves. DUAL enables EIGRP routers to determine whether a path advertised by a neighbor is looped or loop-free, and allows a router running EIGRP to find alternate paths without waiting on updates from other routers.
