CS101 Introduction to Computing Lecture 6 Developing & Hosting a Web page (Web Development Lecture 2)
Today is our 2nd Web Dev lecture During our 1st lecture about the Web … We answered various questions about the Web. How it works, How it is structured, etc. We also commented about the future shape of the Web: the Semantic Web, and how it is different from the Web of today. Today’s Web is targeted squarely at us, humans. Whereas, the Semantic Web is being constructed in such a way that it is easily understandable for the computers
Learning Goals for Today To develop your personal Web page To upload your Web page to VU’s Web server so that it becomes visible on the Internet as http://www.vu.edu.pk/~xxxxxxx/ where xxxxxxx is your user ID
But first … How I developed my personal Web page and made it available over the Internet through the URL http://www.vu.edu.pk/~altaf

This HTML document was developed in a plain-text editor called notepad
After typing the code into notepad, I saved it as index.html To check if I have done everything right, I double clicked on icon of the saved file index.html Double clicking on the icon launched the Web browser displaying my index.html
My Web page is done!
Problem! My Web page is visible only on my computer. It would be nice if it was also visible on the computers of all my friends and relatives as well.
Solution! I need to upload my Web page to a Web server that is connected to the Internet As a result, my Web page will become accessible to anyone with a computer hooked up to the Internet
Upload Process I went to the Web server upload page on the VU Intranet and uploaded my Web page to my account on the VU Web server
Eureka!
My Web page is now accessible from all of the millions of computers connected to the Internet
http://www.vu.edu.pk/~altaf/index.html http://www.vu.edu.pk/~altaf
Enough about mine … Here is how you can develop your personal Web page and make it available on the Internet as http://www.vu.edu.pk/~xxxxxxx
Developing Your Own Web Page Step 1 Open notepad, type in the HTML code, and save it as index.html on your PC’s desktop
Developing Your Own Web Page Step 2 Log on to the VU Intranet and upload that index.html from your PC’s Desktop to your account on VU’s Web server
That is it! http://www.vu.edu.pk/~xxxxxxx Your Web page is now accessible on the Internet through the URL: http://www.vu.edu.pk/~xxxxxxx where xxxxxxx is your user ID
Before we finish for the day, a brief review of the HTML tags …

End of HTML tag review
What have we learned today? We now know how Web pages are built using HTML We also know how to make our personal Web pages available to everyone on the Internet
