Introduction

The Internet is a vast collection of computer networks that spans the entire planet, made up of many smaller networks connected by Standard telephone lines Fiber optics Satellites

More than just an electronic repository for information, the Internet is a virtual community with its own culture and tradition.

3

Intranet: Using similar technologies, an intranet refers

to a private and usually secure local or wide area network within a company or organization.

To access the Internet, you need a network or modem connection that links your computer to your account on the university’s network or to an independent Internet Service Provider (ISP)

WWW:

Once you are connected to the Internet, you can use Web browser software, such as MS Internet Explorer or Netscape Navigator, to access the World Wide Web.

The Web provides a visual interface to the most active and rapidly growing area of the Internet.

5

URL:

Using Web browser software, you navigate the Web and search for information by simply clicking on words, phrases, or images, known as hyperlinks

When you click on a hyperlink, you are telling the Web browser to retrieve a page from a Web site and display it on your screen

Each Web page on the Internet has a unique location or address specified by its Uniform Resource Locator, or URL. An example is:

http://www.misuz.yolasite.com/Bus Info Sys/

HTML Publishing

To create Web pages we will use a certain code called Hypertext Markup Language

We will be interested in applying Internet technologies to knowledge management: Distributing and retrieving information Navigating among information resources Collaborating and sharing information

7

Technologies:

For instance You can SAVE your Excel Spreadsheet and

Charts as HTML to publish it globally You can download financial data from the Web

and update your investment portfolio worksheet Web pages are written or generated in HTML

code and stored in a basic text document. We will use Notepad ++ application to create

an HTML document

8

HTML:

Unlike a programming language like C or Visual Basic, HTML is a markup language that describes how a document should be displayed by the Web browser software

Although Web browsers are similar, one browser may interpret and display an HTML coded document differently from another.

9

HTML codes:

HTML markup codes or tags, appear in pairs and between a left bracket (<) and a right angle bracket (>).

Note the following: We will learn some basic tags as we go along! Identify the “head” area that will appear in the

Web browser’s Title Bar The “body” area that appear in the Web browser

window

Task:

Open Notepad ++ Type the program as it appears on previous

slide Then SAVE it on the hard drive:

Create a new folder Web on the C-Drive C:/ Web/myshop.html Note: Save it as an HTML file!
