The Internet – How Does it Work?

Collection of local, regional, national. And international computer networks linked
together to exchange data and distribute processing tasks

Think of the Internet as a network of interconnected communications lines creating a
sort of highway for transporting data


The main routes of the Internet (analogous to interstate highways) are referred to as the
Internet backbone – across states, countries, continents, oceans (AT&T, Comcast, Verizon
etc.)
Date traveling from the US can arrive in England in less than 60 ms (60 thousands of a sec)

Communication links include telephone lines, cable television, cellular telephone
systems, personal satellite dishes …

This data network runs seamlessly over PCs. MACs, PDAs, servers, routers –
primarily due to a protocol (language – or a set of rules for transmitting date
electronically) called TCP/IP

Computers, Servers, and the Internet
Most of the information that is
accessible on the Internet
is stored on servers
Servers are owned &
maintained by
governments, schools,
universities, corporations,
small business, even
individuals
Servers are computers that
have special server
software to locate and
distribute data requested
by Internet users

The World Wide Web (Web)

one of the (most fantastic) resources on the Internet

hyperlinked and cross-referenced information available for
public access

information located on various computers (called servers)

the Web is a collection of files that reside on computers, called
Web servers.
 Web servers are connected to each other through the
Internet

The World Wide Web (Web)
The World Wide Web (WWW) is not equal to The Internet.
Who Invented the WWW?
Tim Berners-Lee @ European Particle Physics (CERN) lab in Geneva,
Switzerland 1992-93
Developed the Notion of Hyperlinked documents called web pages.
Three Standards:
URL - Uniform Resource Locator
http - HyperText Transport Protocol
HTML - HyperText Markup Language

Web Addresses and URLs

Each computer on the Internet has an unique identification number, called an IP
(Internet Protocol) address

The IP addressing system currently in use on the Internet uses a four-part number.

Each part of the address is a number ranging from 0 to 255, and each part is
separated from the previous part by a period, for example: 106.29.242.17.

Although each computer connected to the Internet has a unique IP address, most
Web browsers use domain name addressing to locate Web sites and pages.
