Transcript of The Internet and the World Wide Web

Internet
A gigantic computer network that connects computers across the world. It has changed the way people communicate, work, and have fun.
World Wide Web
(the web)
Only one part of the internet. It is a way of accessing the huge collection of information, services, and Web sites available through the internet.
Don't be fooled
The internet and web are not the same thing. The internet is like the highway and the Web is like a car that lets you travel from place to place.
Web Addresses
Every Web site has its own address that no other site can use. The address is called a uniform resource locator (URL).
Eye on Domain Extensions
Domain extensions are the three-letters at the end of the domain name. They tell you a lot about the type of Web site you are visiting.
Web Site
The Internet and the World Wide Web
Getting Connected
You need four things to connect to the Internet from your home or school: a computer, an Internet Service Provider (ISP), a modem, and Communications Software.
Communications Software
Includes Web browser software, e-mail software, and software that allows your computer to connect to another computer or network.
Internet Service Provider
An ISP is a company that sells you access to the Internet, usually for a monthly fee. It gives you your own special user name and password so you can connect to the Internet securely.
Modem
It is a device that lets your computer senta to and receive data from other computers or to a network. Three most common types are the telephone modem (provide low bandwidth and moves relatively slow), DSL modem, and Cable modem (supply faster high bandwidth connections).
Web Browser
A Software program that lets you surf web and interact with Web sites. Some of the more popular are Microsoft Internet Explorer, Netscape, Apple Safari, Google Chrome, and Mozilla Firefox.
A Web site is a specific location on the Web that contains a collection of related files and resources by a person, group, or organization. A Web is made up of individual Web pages, called subpages.
