Finding information on the web is made easier by a number of search engines which index and organize material. You should learn to use a variety of these to find what you're looking for. Netscape will eventually give up trying or give an error message. I'd appreciate being informed about any problems in our own web pages. Second, the web supports several types of links.
Web browsers are the swiss army knives of the Internet.
They support a variety of access methods. Usually this is not a problem but there are some special cases you need to be aware of. URL's contain an access method and a resource locator. These and the similar gopher links should work well. Other protocols may cause you some problems.
