Browsers & Internet Fundamentals
World Wide Web
Patrick J. Kidd
- World Wide Web = WWW = W3
- Hypertext = Hyperlinks = Links
- Remote links are on Internet (http://... )
- Local links on your disk (c:\... or a:\... )
- Absolute URL contains all the components
- file:///c:/webpage/html/other/mystuff.htm (Avoid this!!!!!)
- Relative URL contains just the filename
- Recommended. Use relative URLs wherever possible.
- WWW requires TCP/IP with http
- HTML is used to format information to be transferred
- URL provides the address of each document to be retrieved

- Incognito Mode Isn’t As Incognito As You Might Think | Wirecutter - Private browsing = Incognito mode = InPrivate mode
- You can combat some of this tracking with browser extensions, but some browsers disable those extensions in private browsing modes. A trustworthy virtual private network can also provide a potential layer of privacy, though an untrustworthy one may still leak or monitor that data. It’s worth considering a browser that focuses more on privacy by default, like Firefox, Safari, or Brave, instead of Chrome or Microsoft Edge. And for searches, use a search engine like DuckDuckGo, Brave Search, or Startpage instead of Google or Bing. But know that even when you do everything as privately as possible, it’s unlikely that you’re truly anonymous. If you’re searching for information that is critical to keep private, use Tor Browser, which helps cloak your location, doesn’t save your history, and removes most tracking.
- Homepage is a term that is often used in any of the following situations:
- Homepage = main page or first page of any set of hypertext documents published on an Internet Website.
- Web site = all the Web pages (HTML documents) at that address
- Default Homepage
- Filename(s) defined by the Web server administrator. (e.g. index, default, main, etc.). The filename extensions are also defined by the Web server administrator. (e.g. .htm, .htm, .asp)
- URL if filename not specified. (e.g.
-- will load --
- URL that loads automatically with browser (Options or Preferences)

- Tabs or Windows?
- There is currently no way to force a window to open in a new tab in the user's browser by using the "target=_blank" or "target=myNewTargetTabName" attributes of the anchor tag.
- This functionality (window or tab) can only be set in the preferences of the browser.
- In other words, the user is in control. The user can change the settings in his browser.
- In MSIE: Tools (menu) | Internet Options | General (tab) | Tabs (button) | When a pop-up is encountered: [Click on the radio button of your choice] | OK | OK

The Economics of the Web
Patrick J. Kidd
- The core online culture in the Internet has been based on sharing information freely, without restriction and without charge.
- Free online registration required to access some sites is very intrusive and potentially abusive. You must provide rather personal information and then remember your UserID and Password for that site. Do you trust them? Is it worth the trouble, or will you just surf elsewhere?
- e.g. New York Times, Encyclopedia Britanica
- Pay-As-You-Go (per year, per month, per visit, per minute)
- e.g. AOL, CompuServe, MSN
- Like the other media, TV, Newspapers, Periodicals, etc. Do you just tolerate the ads on web sites or do you see them as useful information?
