This open textbook aims to fill the gap between the open-source implementations and the open-source network spec- ifications by providing a detailed but pedagogical description of the key principles that guide the operation of the
We need to define protocols that will be used to carry out tasks. A Protocol is an agreement between computers that specifies how the computers will work together. We’ve actually already seen examples of where we might need protocols on the Internet.
Computer Networking: Principles, Protocols, and Practice was written by Dr. Olivier Bonaventure of the Université catholique de Louvain for teaching Local Area Networks. After The Saylor Foundation accepted his submission to Wave I of the Open Textbook Challenge, this textbook was relicensed as CC-BY 3.0. Computer Networking: Principles ...
computer network can be defined as the collection of computers, printers, and other equipment that are connected (wired or wireless), with the ultimate aim of fostering communications between the devices. The process of creating this connection of devices is known as Computer Networking.
This book explores the key principles of computer networking, with examples drawn from the real world of network and protocol design, uses systems oriented approach to view how individual network components fit into a larger, complex system of interactions.
What is a “Network”? Examples: Mail, phone system, conversations, railroad system, highways and roads. Models, also called protocol stacks, represented in layers, help to understand where things go right or wrong. OSI (Open Systems Interconnection) mnemonic: All People Seem To Need Data Processing.
This document provides advice to the designers of digital communication equipment, link-layer protocols, and packet-switched local networks, who wish to support the Internet protocols but may be unfamiliar with the Internet architecture.
