Web Design Introduction Professor Pepper
2 Computers You use two computers to create your web site. • Web Server, serving all the browsers that ask it for files • Remote (far from your PC) • Gives your web page to everyone in the world Panther Your PC • Only you can see it • Local (right in front of you) • It can get stuff from the Web, but the web can’t ask it for anything.
Web Browser asking Panther You can think of your computer as sending out two different guys to talk to panther. FileZilla sends out the ftp guy and Internet Explorer sends out the HTTP guy. Both address the same server with different names. Mr. panther.adelphi.edu, here is a file for you, and can I take one back with me? Mr. www.adelphi.edu, Can I see a web page of yours? FTP guy HTTP guy
Your Web Design Environment Web Browser (IE, NN, FF, MZ) Web Server file http www.adelphi.edu Panther Your PC webwork pe16132 ftp panther.adelphi.edu Index.html public_html Local Remote File Manager: Windows Explorer File Manager: Filezilla Remote side
FTP Connection FileZilla remote side is showing what is on Panther – far away Windows Explorer and filezilla local side is showing what is on your own hard disk
FTP Connection When you copy files from the local system to the remote system, you are actually sending files to panther. When you copy from the remote system back to local: same thing in reverse
