This free networking PDF, 'Foundation,' Chapter 1 from the Computer Networks: A Systems Approach, Fifth Edition, will teach you what building materials you will need to construct a network from scratch. It explores the requirements that different applications and communities place on the network, introduces network architecture basics and options, discusses the networking and IT groups that should be consulted in network design, examines key elements in computer networks and identifies the key metrics used to evaluate the computer network performance. After reading the summary below, download the computer networking PDF of Chapter 1: 'Foundation,' from, Fifth Edition, by Larry L. Peterson and Bruce S.

Davie (Morgan Kaufmann, 2012). Applications over your network A network must provide connectivity among a set of computers. While some networks limit the number of connected machines, others grow as large as a global wide area network ().

Chapter 1 of Computer Networks: A Systems Approach, Fifth Edition hopes to explain why networks are designed the way they are to help readers better understand how to build a network from the ground up. Ev warrior electric bicycle manuals for sale. This computer networking PDF walks you through how to build a. Network requirements to accommodate application needs Efficiency is the key requirement of computer networks, which is why networks use packet switching as their main strategy. It's too simplistic to view a computer network as simply delivering packets among a collection of computers, however. A network should be thought of as the way to deliver a set of applications distributed over those computers. Success includes both understanding the applications' requirements and recognizing the limitations of the underlying technology.

The challenge is to fill the gap between what the application needs and what the technology can provide. Networks do not remain fixed and must be able to evolve to accommodate technological changes, and networking and IT professionals must be able to manage them. Designing a network to meet those requirements isn't easy. The most basic requirements for a network are that they must provide general, cost-effective, fair and robust connectivity among a large number of computers.

Network architecture as the blueprint Network architectures are general blueprints that guide the design and implementation of your network. The idea of abstraction, which hides your networking details behind a well-defined interface. 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. Abstractions naturally lead to layering. The idea is that you start with the services the underlying hardware offers, then add a sequence of layers, each of which provides a higher level of service.
