How does the internet work?

How Internet Infrastructure Works" 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.

However, just because nobody owns the Internet, it doesn't mean it is not monitored and maintained in different ways. The Internet Society, a non-profit group established in 1992, oversees the formation of the policies and protocols that define how we use and interact with the Internet. In this article, you will learn about the basic underlying structure of the Internet. All About The Internet: Infrastructure. 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. At global regional levels, the principal bodies providing allocation and registration services that support the operation of the Internet globally are: RIPE NCC (Réseaux IP Européens Network Coordination Centre) ARIN (American Registry for Internet Numbers) APNIC (Asia Pacific Network Information Centre) LACNIC (Latin American and Caribbean IP address Regional Registry) AfriNIC (African Regional Registry for Internet Number Resources) Internet Operations American Registry for Internet Numbers Manages the Internet numbering resources for North America, a portion of the Caribbean, and sub-equatorial Africa.

U.S. Army soldiers "surfing the Internet" at Forward Operating Base Yusifiyah, Iraq The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to link several billion devices worldwide. It is a network of networks[1] that consists of millions of private, public, academic, business, and government networks of local to global scope, 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 and applications of the World Wide Web (WWW), the infrastructure to support email, and peer-to-peer networks for file sharing and telephony. Most traditional communications media, including telephony and television, are being reshaped or redefined by the Internet, giving birth to new services such as voice over Internet Protocol (VoIP) and Internet Protocol television (IPTV).

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. These computers connect to the Internet via a tremendous array of communications mediums including phone lines, coaxial television cable, fiber optic cable, serial lines, short-range (in-building) wireless signals and long-range (cellular) wireless signals.

Even with all this variance, the technology of the Internet allows a 10-ounce handheld computer to exchange data with a room-sized mainframe from the 1970's. This Web site has been developed to provide a simple, "layman's" explanation of the unifying technology of the Internet. Zuckerman and McLaughlin : Introduction to Internet Architecture and Institutions. 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.

" An Introduction to Internet Infrastructure We start with a tale of two emails: What happened? And that's it. Still confused? Efficiency. Internet Technical Resources. Internet: The Big Picture (by Russ Haynal) 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. In creating this one web page to describe the "entire Internet", I split the diagram based on the function being performed. I recognize that a company may perform several of these functions. These are the Main Sections: Note for my Alumni: Your referrals are always appreciated. Internet architecture. 2. INTERNET ARCHITECTURE. Connected: An Internet Encyclopedia2.

General background and discussion on the Internet architecture and supporting protocol suite can be found in the DDN Protocol Handbook [ARCH:1]; for background see for example [ARCH:2], [ARCH:3], and [ARCH:4]. The Internet architecture and protocols are also covered in an ever-growing number of textbooks, such as [ARCH:5] and [ARCH:6]. Next: 2.1 Introduction Connected: An Internet Encyclopedia2.
