Chapter 1 Introduction To Computer Network Design Pdf Network This document provides an introduction and overview of computer networks. it discusses the uses of networks, common networking models including client server and peer to peer, protocols and standards, and models for networking including osi and tcp ip. These systems are called has computer network. a network is a group of two of more computer systems sharing services and interacting in some manner. this interaction is, accomplished through a shared communication link, with the shared components being data. put simply a network is a.
Networkdesign Basics Introduction Download Free Pdf Computer Using hierarchical network design principles and an organized design methodology, designers create networks that are both manageable and supportable. computers and information networks are critical to the success of businesses, both large and small. The purpose of this chapter is to provide an introduction to the technology and business use of computer networks. it introduces some of the concepts fundamental to the operation of computer networks. Definition: a computer network is a set of connected computers. computers on a network are called nodes. the connection between computers can be done via cabling, most commonly the ethernet cable, or wirelessly through radio waves. connected computers can share resources, like access to the internet, printers, file servers, and others. We identify key architectural principles in networking, including layering and service models. we provide brief introduction history of computer networking. finally, we provide a brief overview of atm, a networking technology that provides an important contrast with internet technologies. what is the internet?.

Providing communication medium (e mail, videoconferenceing) doing business electronically (b2b, b2c, e commerce) a network with two clients and one server. the client server model involves requests and replies. in peer to peer system there are no fixed clients and servers. some forms of e commerce. Step 1: identify the network requirements. step 2: characterize the existing network. step 3: design the network topology and solutions. the network designer works closely with the customer to document the goals of the project. goals are usually separated into two categories:. Layers should be created where different abstraction is needed. each layer performs a well defined function the function of each layer should be chosen with an eye toward defining an international standard. the layer boundaries should be chosen to minimize the information flow across boundaries. Computer networks chapter 1 introduction to computer networks. ends on following four fundamental characteristics: . elivery: system must deliver data to the correct destin. must be received by only intended device or user. accuracy: the system must deliver d. y because altered and incorrect data is unusable. timeliness: the system must .
