This HTML document was developed in a plain-text editor called notepad

After typing the code into notepad, I saved it as index.htm To check if I have done everything right, I double clicked on icon of the saved file index.htm Double clicking on the icon launched the Web browser displaying my index.htm

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 used ftp to upload my Web page to the IMT Web server

My Web page is now accessible from all of the millions of computers connected to the Internet

Developing Your Own Web Page Step 1 Open notepad, type in the HTML code, and save it as index.htm on your PC’s Desktop

Developing Your Own Web Page Step 2 Log on to the UMT Web server and upload that index.htm from your PC’s Desktop to your account on that Web server

That is it! Your Web page is now accessible on the Internet through the URL: where xxxxxxxxx is your user ID
