Download this computer networking PDF excerpt from “Computer Networks,” a book that addresses the key principles of computer networks. What is ‘layered architecture’ in computer networks?

It is important to lay a foundation before you build a general-purpose computer network. If you’re looking to build a  network that has the potential to grow to global proportions and support increasingly diverse applications, first you need to learn what available technologies can help you to reach your specific goals. 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. Applications over your network A network must provide connectivity among a set of computers.

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. 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. Implementing network software 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. As a result, new applications and services can deployed in a heartbeat.
