4. PC BASICS II
PC Basics I and getting an initial orientation on
developing computer skills focuses more on the
computer itself OFFLINE.
Our goal for this class and succeeding classes is to
maximize the potential of a computer that is ONLINE
that is, hooked up to the World Wide Web!

5. Internet
(A little history & some serious stuff)
∗ Began in the 19602 as military network ARPNET
∗ Made of the items that allow computers to share
information: satellites, telephone and fiber optic
cables, modems

6. World Wide Web
∗ Web sites are written in HTML (Hyper Text Markup
Language) and can be set up by anyone with the
know-how.
∗ Web sites are composed of individual web pages
connected to one another by hyperlinks.
∗ The Internet is like a highway system that allows you
to get from one web site to another.

7. Keeping it simple…
World Wide Web in Plain English
World Wide Web

8. Basic Components of a Web Page

9. Finding Information on the Internet
∗ The World Wide Web carries information
from universities, the government,
businesses, and everyday persons
∗ Each web site has a URL (Uniform Resource
Locator) which is unique to that site. Typing
the URL will take you to the requested site

10. Finding Information on the Internet
∗ The World Wide Web is also indexed in search
engines which allow you to search for just the
information you need.

11. Using URLs
∗ URLs usually start with www (but sometimes no need to type
this in address bar)
∗ For example, www.unf.edu will take you the University of
North Florida.
∗ The ending of the URL can vary depending on what the site is
Some common examples:
.edu (education)
.gov (government)
.org (organization)
.net (network)

12. Keyword Searching in Search Engines
∗ Useful when you don’t have an exact web site in mind
∗ Yahoo and Google are most popular, but there are
several others (Alta Vista, Bing, Ask.com)
∗ Using more than one search engine is good because
not every web site is indexed on all the search
engines

13. Search Engine vs. Metasearch
Engine
Search engines (Google and Yahoo for example search
their own indexed web sites
Metasearch engines, such as Dogpile.com search
multiple search engines
A keyword search in Dogpile will find the results from
Yahoo and from Google.
