URL Definitions
Dissecting a URL
http://www.mccc.edu/student_library.shtmlhttp: You use Hyper Text Transfer Protocol to access
this page// tells us that the page is hosted remotely
www tells us that the page is on a world wide web server
mccc tells us that the page is part of the Mercer County Community College’s network
edu tells us that this site is an educational institution
student_library.shtml is the specific file for this page
Using a URL to your advantage
• Sometimes a page you ask for no longer exists
Error 404 page not found• The page may be gone or the URL may
have changed• Try slicing off the last piece* of the URL
and see what you get. It may lead you to the page you wanted
• This method also works for pages you like and want to look for more on the same topic* You may need to do this a couple of times
Moving back & forward
• You already know to use the back & forward button to move around one page at a time
• By right clicking on your back button, you get a list of the places you’ve visited recently
• Using the dropdown on your address bar also will give you a list of recently visited sites.
Your Browser’s History
• Viewing your browser’s history will give you a more complete list of visited sites
• You can also control how much history you keep as well as deleting your history should you choose
Bookmarks
Bookmarks/Favorites
• Though a history list remembers where you’ve been, it remembers every site you visited both good and bad.
• To remember the “good” sites you’ve run across use bookmarks (IE uses the term Favorites)
• Bookmarks are a personalized list of sites you want to remember
Bookmarks/Favorites
• Most browsers come with some preset bookmarks
• Let’s see what you have, click on “favorites” or “bookmarks” to se what’s there
Bookmarks/Favorites
• The easiest way to bookmark a site is to actually at the site itself
• Let’s bookmark a site– Go to www.mccc.edu– Click on bookmarks or favorites– Add this bookmark– Click on OK to save the bookmark
Bookmarks/Favorites
• After you’ve collected a number of bookmarks, you’ll soon find that the list can be cumbersome
• You will need to organize them into categories/folders (like you do with computer files)
• Remember to delete bookmarks that you no longer need and ones that came with your browser that you don’t want.
Bookmarks/Favorites
• Spend some time deciding what categories you’ll want to break your bookmarks into as well as sub categories
• Music– Jazz– Classical– Hip-hop– Rock
Bookmarks/FavoritesMusic
– Classical– Blues– Country– Jazz
– Swing– Bebop
– Charlie Parker– Dizzy Gillespie
– Fusion– Smooth
Now it’s your turn to work with bookmarks
