Exploring the History of the World Wide Web

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

Networks

A device such as a computer, printer, or scanner, capable of sending and receiving data electronically over the network.

Nodes

A computer server is also called a

host.

A node that provides information or a service is called a server

SERVER

A print server is a network node that provides printing services

PRINT SERVER

A file server provides storage space for saving and retrieving files

FILE SERVER

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

CLIENT-SERVER NETWORK

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

LAN

A wide area network or WAN covers a wider area such as several buildings or cities.

WAN

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

ARPANET

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

INTERNET

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

IP ADDRESS

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.

WORL WIDE WEB

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.

HYPERTEXT

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.

WEB PAGES AND WEB SERVERS

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.

HTML

HTML is NOT a programming language.HTML is NOT a formatting language.

Your Web browser determines how a Web page will look.

HTML

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.

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.

HTML CONVERTER

An HTML editor is a program that helps you create an HTML file by inserting HTML codes for you as you work.

• Ex: DREAMWEAVER

HTML EDITOR

Extensible Markup Language is a 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

XML
