What you will notice different is that websites actually have animations and sounds. Most website pages can now be viewed in multiple framed windows. This permits faster loading of pages where the table of contents or buttons are identical for each subsequent page. It also provides for a unique way of cross-referencing and retrieving information. Product and information-based sites use something called scripting that will allow you to search databases and access secure areas.
Every browser displays web-sites differently.
With the newest versions you will actually be able to view the sites the way they were designed. Older browsers will place images and columns of text in strange places and even change the font styles. The Netscape site also offers a free download of AOL's Instant Messanger. This is a free service that lets you know if your buddies are surfing the web at the same time you are. Expect all the above software to take from 1 to 3 hours to download, depending on all the add-ons you decide to use.
