Topic And Scope Computer networks and internets an overview of concepts, terminology, and technologies that form the basis for digital communication in individual networks and the global Internet

Introduction to Computer Networking 1 collection of machines have been linked both physically and through software components to facilitate communication and the sharing of information. A physical pathway known as transmission medium, connects the systems and a set of rules determines how they communicate. These rules are known as protocols.

Networks class Goal Teach the concepts underlying networks How do networks work? What can one do with them? Give you a basic understanding of the Internet Give you experience using and writing protocols Give you tools to understand new protocols amp applications

1. Parts of a network There are five basic components of a network clients, systems. Servers Sometimes host called computers , s vers are powerful computers applications and connect to resources that are shared Clients These computers are used by the users of the resources such as hard disks and printers.

Computer Networks Fundamentals WHAT IS A NETWORK? A network is simply two or more computers that are linked together. The most common types of networks are Local Area Networks LANS and Wide Area Networks WANS.

A network refers to two or more connected computers that can share resources such as data, a printer, an Internet connection, applications, or a combination of these resources.

The second reason is that the computer networking community is a strong participant in the open-source movement. Today, there are high-quality and widely used open-source implementations for most networking protocols.

Preface Computer networking is a fascinating field that has interested many for quite a few years. The purpose of this brief book is to give a general, non-mathematical, introduction to the technology of networks. This includes discussions of types of communication, many networking standards, popular protocols, venues where net-working is important such as data centers, cloud computing and

Router a communication computer that connects different types of networks using different protocols. B-router or BridgeRouter a single device that combines both the functions of bridge and router. Gateway a network device that connects two different systems, using direct and systematic translation between protocols.
