Buying and Using a Computer Modem

Anyone over the age of 25 or so knows the sound well. That high-pitched electronic whine-and-fuzz of a computer connecting to the Web. Dling-dling-dling-dling-shhhhhhh....

That's the sound of a computer modem doing its job. Once an enormous, complex device, today's modems are silent, small and much faster at what computer modems do: turn a digital stream of 1s and 0s into sound, then from sound back into digits.

Finding the right modem for your business needs is a matter of narrowing your choices in these four key areas:

1) Modem type. Are you seeking a cable modem, DSL modem, dial-up modem, laptop modem or another kind?

2) Features you want included in your modem, such as wireless capability.

3) Brand. Shopping by brand -- such as Motorola, Linksys, Cisco, Netgear or others -- can help narrow your choices.

4) Price. And of course you may have a specific budget, so look for models under $100, for example, if your funds are limited.

Buying the right computer modem for your connection

Dial-up Internet is quickly becoming part of the past as broadband rolls out across the United States. Faster DSL models are now more common, while cable modems are a popular alternative for cable TV customers.
Try: There is no "right" modem, but in general a DSL or cable modem will give you the high-speed Internet experience you expect. Well know modem makers include Unitech, D-Link, Motorola, Linksys, Zoom, HP and Cisco Systems. See computer modem choices at the Business.com directory on computer modems.

Understanding cable modem choices

If you order your Internet service from the cable company, you will be sent or have to buy a cable modem. Here, your options are an external modem, an internal modem or a set-top box (this last one always comes from the cable company).
Try: Installing an external model is relatively simple, it's almost plug-and-go and just sits on the desk next to your computer. Internal modems have to be installed and thus work on on desktop PCs. A set-top box presumes you will be surfing the Web through your TV, not a computer. A decent but not-too-complex explanation of cable modem choices is at Cable-Modems.net.

Understanding DSL modem choices

A DSL modem (sometimes called an ADSL modem) is the one you'll use if you buy broadband from the phone company. It plugs into a normal phone jack, then you telephone can still be plugged into it and work normally.
Try: DSL modems were once quite hard to use, even requiring a special line to the house. No more. With some minor installation, a DSL modem is up and running fast in a few minutes in most cases. Read up on the technical explanations at How Stuff Works.

The difference bewteen a modem and a router

In short, a modem turns the "sound" of the Web into information for your PC to show. A router, meanwhile, is like a traffic cop -- allowing more than one computer to connect to the same modem, to printers, and to each other. Yet, some manufacturers combine the two into one device, for simplicity's sake.
Try: Do you need a router? For a single home computer, in most cases, no. But if you have a laptop that can pick up wireless signals, a wireless router connected to a modem at your broadband connection can free you from having to work next to the cable or phone line. Read more on routers and their uses.

For on-the-go Web, consider a wireless modem

Laptop computers come with a standard slot, usually on the side, called a PC card slot. Into that goes a wireless modem, a narrow metal card which, coupled with a paid account, will connect to the Web anywhere you can get a cellular signal.
Try: Not to be confused with Wi-Fi, a wireless modem will work just about anywhere. It's a little slower (although improving as cellular networks invest) but it works just fine for e-mail and moderate-speed Web surfing. Some vendors of wireless modem service including Verizon, Sprint and AT&T, or see more wireless modem vendors at Business.com.

Cable or DSL? Often, the question is better phrased "which company do you dislike least, the phone or cable company?" Seriously, service disruptions are bad news. Ask around about reliability.
Hold out for a deal. Any broadband provider trying to earn you business should give you a modem and plenty of networking cables.
Don't know a coax from a split line? Ask your provider rates on installation or call up Geek Squad for help. It isn't rocket science, but the initial set-up -- especially if want security like a firewall -- is a bit hairy.

Tips & Advice to help you make your decision on Computer Modems

The type of modem that you buy for your computer will depend on the type of internet connection the computer is using. Some places still use dial up internet, although in places where a faster connection is available, the choice usually is made in favor of speed. DSL is popular, but people who have cable TV often choose this option to access the internet. All of these different type of internet access require a different type of modem. Many times the modem will be included as part of the installation cost of new phone or cable service, but there are many other sources available.
