  13. Two Types of Computers • Servers: contain information to share • Clients: machine with a web browser to access that information Server Client Web Server Pages Browser

  14. The Browser BROWSER: Web page processor (software program) BROWSER software on your machine (client) > interprets instructions to display a web page > usually retrieves web page from server Instructions Text

  15. Web Pages • Text file that says what to display • Web pages use HTML (HyperText Markup Language) • a little history • Two types of information • Instructions on how or what to display • Text (the data) • Instructions are in the form of tags • < command > • Do NOT need any special tools to build • BUT tools can make it easier

  16. General Structure: HTML Page <html> <! --- most important item in head is the title --- > <head> <title>Put your title here</title> </head> <! --- body is where the “good stuff” is --- > <body> What will appear on the page <br /> Here … and there </body> </html> WARNING: This is not a complete page.

  17. Anatomy of a URL • Protocol: server-name/file-to-display HOWWHEREWHAT • Protocol: usually http • Have you ever seen others? https? telnet? ftp? • Server-name • The computer’s name • Usually begins with www • Usually ends with 3 characters that define the kind of site • However, there are no rules: as long as its registered, you can get there • File-to-display • Can be a whole path (just like Windows)

  18. Choosing Tools • Very fancy tools exist • Ease of building vs. Control • Cost • We will use an editor that help you get it right • We will NOT use tools that hide what you are doing • We will use Komodo Editor

  19. Why Learn HTML? • Mainly, to demystify • But more than that -- even if using a package • Sometimes you … • can’t figure out how to make it do what you want • can’t figure out what is wrong • just want to make some minor changes • If you understand how it works, YOU are in control

  20. Sharing Web Pages • Using Komodo Editor creates a web page on your machine • You can use the browser to look at it • But who else can see it? • NOBODY • Want it to be on a SERVER • UNC provides: ISIS

  21. UNC Site • UNC website • Everything that is going to be available on the web must be in your public_html folder • Treats index.html as your home page • Default is “This page is blank” • Creating WWW Pages at UNC-CH • http://help.unc.edu/?id=108

  22. How to Transfer • UNC discusses sftp (Windows) and fetch (Mac) • We will use Filezilla • Why? • Simpler interface • Cross platform
