The Internet BTA3O

What is the Internet? 4 Internet: a gigantic system of computers all over the world linked together in a “network”; mainly using telephone lines to access and provide information on a wide variety of items to the many millions of people who connect to the network. It consists of a large collection of services that people can use, including , the World Wide Web, and Usenet, among other services.

Network 4 Network: a group of computers that are connected via communications equipment to share resources.

LAN 4 LAN (Local Area Network): a network of computers in one geographical location, such as a building or an office; some LAN’s are connected to the Internet, giving each user on the LAN access to Internet resources.

WAN 4 WAN (Wide Area Network): a network that spans many geographical locations; several LANs (each in different buildings) that are connected to each other would form a WAN.

WWW - World Wide Web 4 World Wide Web: a collection of millions of individual Web pages displaying text, colour, graphics, sound, animation, and more. Each page has its own web address or URL; is the most popular resource on the Internet, along with .

Web Page 4 Web page: a collection of text and pictures usually about a single topic. A web page is viewed using a browser. The URL (Uniform Resource Locator) is entered into the browser in order for the computer to know where the user wants to go on the Internet. Exact spelling of URL’s is essential to reach a particular Web site.

URL 4 URL (Uniform Resource Locator): the current method for specifying addresses of sites on the Web; for example,

Browser 4 Browser: Software that allows you to view Web pages and move around the World Wide Web; for example, Netscape Navigator and Microsoft Internet Explorer.

Intranet 4 Intranet: A closed network of computers, usually computers in a single office or company, that are all connected or networked to deliver internally and not available to the outside viewers.

ISP 4 ISP (Internet Service Provider): a company that will, for a fee, connect your computer into the Internet; for example, Bell Sympatico, Rogers Cable.

Server 4 Server: a computer that stores files as a central resource for other computers, called clients, that can connect to the server to get files for themselves.

Client/Server Software 4 Client/Server Software: software split between two programs: clients and servers that can be used at the same time; allows users to run programs on their personal computers that interact with databases on host computers; for example .

What do people use the Internet for?   E-Business  Group Discussions  Accessing files, data, sounds, pictures  Research  Surfing – browsing the net as a source of entertainment  News letters  Computer software and hardware support  Distant Education  Internet Phone  Internet Chat Rooms  Internet Conferencing  Video Conferencing

History of the Internet The earliest ancestor of the modern Internet was called the ARPANET, short for the Advanced Research Projects Agency NETwork. The ARPANET was born out of both scientific and military needs. Scientists and military experts in the 1960’s needed to share information and research data even if a nuclear war or a natural disaster, like an earthquake, destroyed large sections of their communications system.

History... If any part of the ARPANET ever went down, the ARPANET had the ability to reroute computer data and information down different network paths, ensuring that at least part of the computer network remained alive.

History... In the mid 1980’s, the National Science Foundation (NSF) funded six supercomputers for scientific research. The computers were located in Princeton, New Jersey; San Diego, California; Champaign, Illinois; Pittsburgh, Pennsylvania; Ithaca, New York; and Boulder Colorado.

History... In 1986 NSF expanded its network by funding the NSFNET. Since there were only a few supercomputers, it was decided that scientists living in other parts of the country should be allowed to log in to the supercomputer remotely. To accomplish remote access, a communications backbone was created. The backbone was a system of high-speed phone lines carrying computer data. The backbone first connected the supercomputer sites to each other. ARPANET was later connected and absorbed by NSFNET.

History... The NSFNET established a backbone to which everyone with the necessary equipment and software could connect. Soon, colleges and universities from all over the country hooked to the backbone. The National Aeronautics and Space Administration (NASA), the Department of Energy, and other government agencies soon hooked up as well. Later, elementary and secondary schools were encouraged to join the new system, and the modern Internet was born.

History... Many companies were formed to meet the demand for Internet access. They began to provide access to the Internet for a fee. Companies like Prodigy, America Online and CompuServe provided Internet connections to businesses and homes. The number of Internet hosts has grown from a few hundred to millions today.

Accessing Information on the Internet 4 Public Domain – Programs unprotected by copyright law for free, unrestricted public use. This includes programs, graphics, video, audio, animations, and/or text.

Accessing... 4 Shareware – Authors of shareware retain copyright to their work. They make their programs available to the public with the belief that if the user likes the program, he or she will purchase the program from the author. Users may copy and distribute the program freely.

Accessing... 4 Copyright – This refers to information/material, which may not be copied, reproduced, or converted to any other form in whole or in part without prior written approval of its creator. This includes programs, graphics, video, audio, animation, and/or text.

Accessing... A search Engine is a specialized Web Site that enables you to find information on a specific topic by typing a phrase or keyword. Examples are: Alta Vistahttp:// AskERIChttp:ericir.syr.eduhttp:ericir.syr.edu Excite Searchhttp:// Yahoo Searchhttp:// InfoSeek Searchhttp://ww2.infoseek.comhttp://ww2.infoseek.com
