Computer networks link your machine to computers throughout the world
Internet
global network of computers
no one owns or controls the whole thing
30-40 million people have access
How does it work?
Browser: software to look at web pages (Netscape Navigator)
Server: software that provides service
The client (Web browser) on your machine sends a request to a server.
The server sends the file requested by the browser.
The file contains data and formatting information
The browser displays the file on the screen.
Uniform Resource Locator (URL)
Every page has a unique address (URL)
domain/directories/filename.ext
The URL for SCU is:www.scu.edu
The Web page for this course is:www.cse.scu.edu/~lseiter/coen176/index.html
HTML Document: www.ncsa.uiuc.edu/General/Internet/WWW/HTMLPrimerAll.html

HTML
HTML stands for HyperText Markup Language.
Structural vs. Physical Markup
PLAIN TEXT FILES: can use with any editor.
Basic idea: Insert embedded commands (tags) into text files to tell the browser how to format the related text and where to put an image and where to find an image file.
Data is transferred between the browser and the server in http (hypertext transfer protocol).

The quickest way to start: When you see a nicely designed page and wonder how it is done, select "view->document source" in Netscape to see the source code. You can save the document in your file sys.
Copying html file and creating your own from it is ok. Copying someone else's image may not be ok.
