Also, explore the requirements that different applications and communities place on the network, key elements in computer networks, and the metrics used to evaluate the computer network performance. Latency is how long it takes a message to travel from one end of a network to the other and is measured in time. . r � � Q @Q Q %z �� �� �� �� �� � �� 0u �� `� �� �: �� o �� �� �� Photoshop ICC profile ���ICC_PROFILE �ADBE prtrGRAYXYZ � acspAPPL none �� �-ADBE cprt � 2desc � gwtpt \ bkpt p kTRC � text Copyright 1999 Adobe Systems Incorporated desc Dot Gain 20% XYZ �� �-XYZ curv 0 @ P a  � � �Du��R��Y��9��.��9��W�"�� a � By now, you should already know that computer networks are not a random mess of “just plug this device” into the router, and magic will automatically happen. One of the things that has made the Internet such a success is the fact that software running in general-purpose computers provides so much of its functionality, which means new functionality can be added easily. 2. Wide area network (WAN) To read the full book chapter, download this free computer networking PDF using the form above. Designing a network to meet those requirements isn't easy. Computer networks have used various types of physical media to exchange information, notably : • electrical cable. expected use or capability of the computer. . The idea of abstraction is to make a model that can capture an important aspect of the system, but the challenge is to identify abstractions that simultaneously provide a service that proves useful in a large number of situations. We can categorize them according to their size as well as their purpose. Types of Networks Based on Geographical Location Local Area Network (LAN). It is important to lay a foundation before you build a general-purpose computer network. About the authors:  Author Larry Peterson is the Robert E. Kahn Professor of Computer Science and Director of the Princeton-hosted PlanetLab Consortium. Information can be transmitted over different types of electrical cables. While the term computer can apply to almost any device that has a microprocessor in it, most people think of a computer as a device that receives input from the user through a mouse or keyboard, processes it in some fashion and displays the result on a screen. It's too simplistic to view a computer network as simply delivering packets among a collection of computers, however. A network must provide connectivity among a set of computers. . There are various types of computer networks available. . Some of the different networ… Number of systems connected in LAN may vary from as least as two to as much as 16 million. A computer network is mainly of four types: LAN(Local Area Network) PAN(Personal Area Network) . While some networks limit the number of connected machines, others grow as large as a global wide area network (WAN). .
