isr.co.ro : glossary Dialup A temporary network connection you make over the regular phone system, rather than one through an internal network or permanent leased line. Most likely, this is the way you'd connect to the Internet or an online service at home or a small business. While dialup connections are fine for reading information and for interaction on your own schedule, they are not considered suitable for posting World Wide Web pages, because you may not be connected when someone else wants to access pages you supply. Because your data must pass through a telephone network designed primarily for voice data, dialup connections are usually limited in speed. If too many people try to access the same group of connections, you may get a busy signal instead. Depending on the policy of your network provider, a dialup user may also get a different temporary network address on the Internet each time, rather than a permanent address. That makes it impossible to use certain more technical programs.
