One of the greatest things about the Internet is that nobody really owns it. It is a global collection of networks, both big and small. These networks connect together in many different ways to form the single entity that we know as the Internet . In fact, the very name comes from this idea of interconnected networks. Since its beginning in 1969, the Internet has grown from four host computer systems to tens of millions.
Infrastructure description Computer Networking: Global Infrastructure for the 21st Century By Vint Cerf Administration The overall responsibility for managing Internet Protocol address or domain names at upper levels is vested in the Internet Assigned Numbers Authority (IANA) , which delegates the actual administration of most functions to other bodies.
The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite ( TCP/IP ) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support email.
Introduction The Internet is a global network of computers which allows people to exchange data worldwide instantaneously. This simple sentence is the most accurate way to summarize the definition of "Internet," but it does not do justice to the phenomenal technology behind the Internet. The Internet spreads across all seven continents and includes computers that range from 35 year-old mainframes to modern home PCs to handheld devices.
Introduction to Internet Architecture and Institutions Ethan Zuckerman & Andrew McLaughlin August, 2003 Table of Contents Introduction Introduction to Internet Architecture and Institutions was originally created as the introductory module of BOLD 2003: Development and the Internet , an online course taught by faculty and fellows at the Berkman Center for Internet and Society at Introduction to Internet Architecture and Institutions provides you with an introduction to the technical and organizational structure of the Internet. First, using simple examples, you will be introduced to the way the Internet works, the processes involved in keeping it running, and the entities that have put it all together and continue to do so. You are encouraged to follow the links available in the first section, "An Introduction to Internet Infrastructure."
Welcome to "The Big Picture" of connecting through the Internet to reach online resources. The purpose of this page is to answer the question: "What are the major pieces of the Internet, and who are the major players in each segment?" If some of these links don't make sense, it's because you are not an "alumni" of my internet courses ;-) This page displays the main pieces of the Internet from a User's PC... extending all the way through to the online content. Each section mentions the most significant parts of the Internet's architecture. I also provide links to the top "couple of vendors" in each category, and then an external link to a more extensive lists of vendors.
