Why Broadband is now Required for Internet Access

updated October 2008

    For those of you who may have purchased your first home PC in the late 1980s or early 1990s, telephone line modems may seem like a 15-20 year old technology whose era is nearing its end. However, the elite few who have dealt with telephone modems for the past 40 years have one of two reactions to to subject matter of this article: (1) "I don't want to let go of ol' reliable!" or (2) "Let's toss it."

    Before I go too much further, let's make sure everyone reading this is on the same page. First let's make sure everyone understands the definition of a modem.

(mōīdem) (n.) Short for modulator-demodulator. A modem is a device or program that enables a computer to transmit data over, for example, telephone or cable lines. Computer information is stored digitally, whereas information transmitted over telephone lines is transmitted in the form of analog waves. A modem converts between these two forms.

    You might notice the fact that I specifically stated that the "telephone modem" technology is about 40 years old. This is because , as many of you might know, Cable Modems and DSL Modems now exist (and in abundance) in homes and offices of those using High Speed Internet connections, also known as Broadband.

Broadband: A type of data transmission in which a single medium (wire) can carry several channels at once. Cable TV, for example, uses broadband transmission. In contrast, baseband transmission allows only one signal at a time.

    Right now, there are two main types of broadband, or high speed Internet connections: Cable, which is usually provided by your local Cable-TV provider, and DSL (Digital Subscriber Line), which is provided by your telephone company (or a separate company which leases access to the telephone lines to provide the service). Both can provide Internet access at speeds much higher than your average dial-up telephone modem could ever provide. Many of these services advertise speed up to 50-times faster than a dial-up modem.  I'll save the debate over which service is faster (DSL or Cable) for another date, but for now let's concentrate on moving everyone off of the old fashioned dial-up connections.

Here are the frequently asked questions from those switching from dial-up to high speed/broadband.
