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

server

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 Resource and Services of the Internet

Web sites

Email

Search engines

Downloads and uploads (e.g. music)

Instant Messaging – voice conferencing, web cam (Skype, Yahoo Messenger, MSN …)

Online Shopping

P2P file sharing (enabled by software such as limewire, Kazaa, BitTorrent …)

Generation of the YouTubers

FaceBook, Bulletin boards (SIG, usenet, forums, newsgroups …)

Blogs (WeB LOG)

News and broadcasting




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




Access to Internet and the World Wide Web

Accessing the Internet: Internet Service Providers (ISPs) e.g. Comcast, Verizon, PDT …

Information - flow of packets

ISPs

router




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.




Parts of the URL

Anatomy of a URL address -

http://www.disney.com/index.html

http:// is the Internet protocol to use (WWW)

www. is the name of the computer system

.disney is the domain name
