What is the Internet Quiz

Internet is a worldwide group of connected networks that allow public access to information and services. Developed in the late 60's and early 70's by the US Department of Defense as an experiment in wide-area-networking to connect together computers that were each running different system so that people at one location could use computing resources from another location. No single organization owns or controls Internet. Internet has estimated 500 million users around the world. In essence, the Internet is just a very large collection of millions of computers sharing information. When we go onto the Internet, we are actually connecting to a "server", just a fancy word for a computer dedicated to providing information on the Internet, and looking at the files on it. Don't be alarmed, this does not mean that anyone can come and look at the files on your computer. We can only see files that the "server" allows, and wants, to be viewed. HOW THE INTERNET WORKS

People can connect to the Internet through an organization such as a school or company, an online service provider (OSP), or an Internet service provider (ISP).
To be able to get internet connection you can use existing telephone line, cable television line, or high-speed service like DSL (Digital Subscriber Line).
Dial-up access Method of connecting to the Internet using a modem in a computer and a standard telephone line. Dial-up access is used by many homes and some small businesses and is an easy and inexpensive way for users to connect, but it is a slow-speed technology. A modem converts digital signals into wave format to go over telephone lines and then at destination waves are converted back into digital. Its dial-up top speed is 56 Kbps.

Digital subscriber line (DSL)
DSL is a technology that provides a higher-speed Internet connection to a user with regular copper telephone lines.
Cable Modem
Cable modem provides high-speed Internet connections through the cable television network. Cable Modem requires 2 pieces of equipment: a network card, a device that’s designed to connect a personal computer to a local area network and a cable modem – device that changes computer’s signals into a form that can travel over cable TV links.

Both DSL and a cable modem access are referred to as always-on connection because your computer is always connected. The top speed for both access types is around 1.5 Mbps (25 times faster than a dial-up), although cable modems tent to be faster. Cable modems usually more expensive than DSLs.
Typically schools and business connect to a local area network that is connected to the Internet and these connections are frequently always-on connections provided by Internet Service Providers.

INTERNET SERVICE PROVIDERS (ISP) An ISP (Internet Service Provider) is a company that maintains Internet computers and telecommunications equipment in order to provide Internet access to businesses, organizations, and individuals. ISPs provide temporary connections to individuals and companies for a fee. Business or school network connected to the Internet mostly trough ISP. ISPs themselves are connected to one another through Network Access Points (NAPs). AOL, AT&T and Verizon are the examples of ISP. When choosing an ISP you should look at the cost of their monthly services.
The World Wide Web, or simply Web, consists of a worldwide collection of electronic documents that have built-in hyperlinks to other related documents. These hyperlinks, also called links, allow users to navigate quickly from one Web page to another, regardless of whether the Web pages are located on the same computer or on different computers in different countries. These documents or Web pages are stored on computers called web servers located around the world. The World Wide Web started in the early 1990s and it has evolved into a global electronic publishing medium and increasingly, a medium for conducting electronic commerce.
Entering the Web site address in your web browser or clicking a link sends a request to the web server which hosts this web site. The web server sends the web page to your computer and your web browser displays it on your screen. The Web site is just a collection of related web pages and associated items, such as documents and pictures, stored on a Web server.
Web pages (such as the one you are looking at now) are electronic document on the Web, written in a computer language called HTML (Hypertext Markup Language, which can contain text, graphics, audio (sound), and video and usually has built-in connections to other documents as well as interactive features, such as data entry forms.
WEB SITES:A website is one or more web pages that relate to a common theme, such as a person, business, organization, or a subject, such as sports. The first page is called the home page, which acts like a starting point, indicating the content on the site and its purpose. From the home page, you can click hyperlinks to access other web pages. The example of a web site could be or
URL (Uniform Resource Locator): Each page has a unique address known as a URL (Uniform Resource Locator), which identifies its location on the server.
URL is an address that points to a specific resource on the Internet; can indicate an Internet site, a specific document at a site, and a location within a document at a site. A URL starts by naming the communication protocol that is to be used. Hypertext Transfer Protocol is a set of rules that define how pages transfer on the Web. It is also called http.
The next thing the URL tells you is the name of the server that holds the web page you want. This server’s name is called domain name. For example: – the domain name is; – the domain name is The www in front of each domain name indicates that it belongs to the World Wide Web.You will notice that these domain names always end with on the of the following: ".edu" (education) ".com" (commercial), ".mil" for military, ".org" for organization or “.net” for personal non-commercial web sites. These three-character words are called domain name prefix. You can find some other domain name prefixes on the internet like: country identifiers (.ru, .it, .ca and so on). They usually indicate what language these pages are using
URL address also contains a web page name with its extension (sometimes it has a directory name in front of the web page name):
Web Browser:Web browser software is a program that interprets and displays Web pages and enables you to link to other Web pages. Each time a browser is started, a home page appears. The browser retrieves Web pages using a Uniform Resource Locator (URL), which is an address that points to a specific resource on the Internet. Browsers display hyperlinks either as underlined text of a different color or as graphical images. A linked document can be displayed by clicking the hyperlink or by typing its URL in the location or Address text box
The two most popular browsers are Microsoft Internet Explorer and Netscape Navigator. AOL is also is a browser, although it is mostly based on Internet Explorer. All browsers basically work the same way. Once you know one, you can easily learn the other
The most useful buttons on your browser toolbar include:
Back -- Returns you to the previous page
Forward -- Returns you to a page you have backed up from
Home -- Takes you to a home page specified in the browser preferences
Reload or Refresh -- Downloads the web page from the server again.
Stop -- Stops the browser from loading the current page.
Print -- Lets you make a hard copy of the current document or frame loaded in your browser
