Most ISPs today also offer telephone service. Many of the big internet companies, in fact, were in the telephone business long before there was internet. That may be one reason why DSL is one of the most common means for people to get online. DSL uses existing phone lines, which means no poking holes in the walls. But DSL is different than dial-up connections, in a few important ways. The first is that when you are online using DSL, this connection won’t interfere with incoming our outgoing phone calls. Secondly, DSL is always “on.” Last but not least, DSL is much faster than dial-up. Using the latest technology, DSL can actually be up to 35 times faster than dial-up. This additional speed means web pages that download without having to wait, which makes spending time online much more enjoyable.
