  1. Exploring the History of the World Wide Web Web Design New Brighton High School

  2. Networks • A structure that links several points, called nodes allowing for the sharing of information and services

  3. Nodes • A device such as a computer, printer, or scanner, capable of sending and receiving data electronically over the network. A computer server is also called a host.

  4. SERVER • A node that provides information or a service is called aserver PRINT SERVER A print server is a network node that provides printing services

  5. FILE SERVER • A file server provides storage space for saving and retrieving files

  6. CLIENT-SERVER NETWORK • A computer or device that requests services from a server is called a client. Thus a client-server network is a network design in which several clients access information provided by one or more servers

  7. LAN • A local area network or LAN is a network confined to a small geographic area, such as within a building or department.

  8. WAN • A wide area network or WANcovers a wider area such as several buildings or cities.

  9. ARPANET • A wide area network which started with two network nodes at UCLA and Stanford connected by a single phone line. • Created by the United States Defense Advanced Research Project Agency

  10. INTERNET • A global system of computer networks that use the standard internet protocol suite (TCP/IP) to serve billions of users worldwide

  11. IP ADDRESS • An address used to identify any device connected to the Internet • Consists of four numbers separated by periods (also called a 'dotted-quad') and look something like 127.0.0.1.

  12. WORL WIDE WEB • An interface that makes the Internet accessible to the general public. • Timothy Berners-Lee, at CERN nuclear research facility in Switzerland, developed the idea of hypertext documents that enables scientists to easily navigate from one topic to another. They were able to locate and share data with minimal training and support.

  13. HYPERTEXT • A method of organization in which information is not presented linearly, but in whatever order is requested by the user. • The key to hypertext is the use of links, which are the elements in a hypertext document that allow you to jump from one topic or document to another.

  14. WEB PAGES AND WEB SERVERS • Each document on the World Wide Web is a Web page. Web pages are stored on Web servers, which are computers that make Web pages available to any device connected to the Internet. To view a Web page, the end user’s device needs a software program called a Web browser, which retrieves the page from the Web server and renders it on the user’s device.

  15. HTML • A Web page is a text file written in Hypertext Markup Language or HTML. A markup language is a language that describes the content and structure of a document.

  16. HTML • HTML is NOT a programming language. • HTML is NOT a formatting language. • Your Web browser determines how a Web page will look.

  17. WORLD WIDE WEB CONSORTIUM • The World Wide Web Consortium or W3C is a group of Web developers, programmers, and authors that created a set of standards or specifications that all browser manufacturers are to follow. • The W3C has no enforcement power, but because a uniform language is in everyone’s best interest, the W3C’s recommendations are usually followed.

  18. HTML CONVERTER • An HTML converter is a program that translates text written in another language into HTML code. • Converters free you from the task of typing HTML code; but converters create large and complicated HTML files rendering it more difficult to edit.

  19. HTML EDITOR • An HTML editor is a program that helps you create an HTML file by inserting HTML codes for you as you work. • Ex: DREAMWEAVER

  20. XML • Extensible Markup Language isa markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. • Developers can create documents that obey specific rules for their content and structure
