Dialup Internet: What's the Use?
Dialup internet is one of the most reviled things in today’s online communities. Slow and prone to disconnection, it is the bane of anyone trying to move large files across the network. But is it entirely useless? Not really – there are actually some circumstances in which dialup internet can be a good thing. The first time someone with broadband will recognize the usefulness of dialup internet is when their cable or satellite connection goes down. In certain areas, the cable will lose its internet capability at what seems to be the slightest little wind, and satellites can have a hard time sending signals through thick clouds. It is with a rueful mood that the customer will then realize that their phone is still working perfectly. This can cause desperate searching for an old AOL disk, especially for internet businesspeople who are literally losing money every minute they don’t have a connection. Another time dialup can come in handy is if a person simply doesn’t want to have to pay for cable. Dialup is typically much cheaper. This makes it popular among the young, as well as in all age groups in some less-well-off countries. Some areas simply don’t have access to broadband internet. When it’s dialup or nothing, suddenly dialup starts looking fine enough. To a city-dweller, it may seem that this problem could only affect undeveloped countries, but in fact, there are many rural areas in the United States and Canada with this very situation. Phone lines, however, are almost ubiquitous, making it possible to dial in to the internet from almost anywhere. Dialup internet is also great for those who only use the net occasionally, or for simple tasks like checking email. While internet businesspeople often have large files to deal with and would be driven “right up the wall” if forced to use slow dialup for an extended period, it just doesn’t make sense for occasional users to make the ongoing investment of a cable or satellite connection. For these reasons and more, dialup internet is not truly obsolete. Whether you’re a light internet user or a businessperson who wants a backup connection, having the ability to just dial up a connection comes in handy.
