Educational uses of the web:
“From surfing to serving”
• Initially people see the Internet as a vast
source of information
• The web as a distributed hypermedia
Hypertext & Hypermedia
•
•
•
•
•
Our class web page as a hypertext
What is hypertext?
Text that can be read in multiple ways
Print hypertexts?
Hypermedia:
hypertext+graphics+sound+video+animation+etc.
= hypertextual multimedia
The World-Wide Web
• A distributed hypermedia
• Different parts can be on different
computers all around the world, with
hypertextual links via the Internet
Web surfing
• Web “surfing”
– Advantages
– Disadvantages
Surfing to Serving
• Web Serving:
– Advantages
– Disadvantages
Search Engines
• Databases of web resources
• Two kinds
– Directories (human classified) - Ex: Yahoo
– Web crawler-based (not human classified) Ex: Excite
• Which to use?
– Use whichever ones you find useful
– When you don’t find one useful, switch to
another
Understanding URLs
• A unique address for each web resource
• Structure: what + which computer + which
file
• Example:
http://www-tep.ucsd.edu/courses/tep231/su99/default.html
• What kind of resource: http:// -> Web file
• Which computer: www-tep.ucsd.edu
• Which file: courses/tep231/su99/default.html
Understanding Computer Names
• Domain names: used both for computer
names in URLs and in email addresses
(whatever is the to the right of the @ sign)
• Like a postal address, but with “.” instead of
new line as separator
• Most general to most specific, right to left
Example:www-tep.ucsd.edu
• From the right: edu -> US higher
education institution
–
–
–
–
–
–
–
com --> US commercial institution
gov --> US federal government
org --> US non-profit
us --> US
mx -> Mexico
au -> Australia
Country code list: http://externic.net/iso.htm
Example:www-tep.ucsd.edu
• Next to the left: ucsd
– University of California, San Diego
• Email example: j-levin@uiuc.edu
– University of Illinois. Urbana-Champaign
Example:www-tep.ucsd.edu
• Next to the right: www-tep
– A particular computer in the room next door
• Another example: www.ed.uiuc.edu
– ed --> computers in the Education Building at
UIUC
– www --> a particular computer in the basement
of the Education Building
Sending/saving URLs
• Have to get the URL exactly right
(sometimes case mAtTeRs; no spaces ever)
• Copy & paste is best
• Emailing from your web browser
– Advantages: can do anywhere
– Disadvantages: need to set & then unset email
preferences
• Emailing yourself
Using URLs to evaluate web sites
• Largest level domain: .edu vs. .com vs. …
• Subdomain elements: .ed.uiuc vs. .cs.uiuc
• Directory elements: /students/joe/ vs.
/facstaff/chip/
• Institutional vs. personal pages: /~jlevin/ vs.
/deans/

ordered lists, with URLs, short descriptions,
