Two Types of Computers Servers: contain information to share Clients: machine with a web browser
to access that information
Server Client
Web Server
PagesBrowse
r
The BrowserBROWSER software on your
machine (client)> interprets instructions to display a web page> usually retrieves web page from server
BROWSER:Web page processor(software program)
InstructionsText
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
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.
Anatomy of a URL Protocol: server-name/file-to-display
HOW WHERE WHAT 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)
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
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
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
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
How to Transfer UNC discusses sftp (Windows) and
fetch (Mac) We will use Filezilla Why?
› Simpler interface› Cross platform
