In a Flash: Internet Service Providers Explained

I distinctly remember when my brother in California called me to brag about how quickly he could open a webpage using his new DSL Internet provider. I was living in rural Ohio, still stuck with a slow dialup connection. He went on to describe how he could open up a website as quickly as a Microsoft® Word file. Thankfully, now that dialup is largely passé, most of us can relate to the latter experience.

Potential ISPs

Below is a brief tutorial of Internet Service Providers (ISPs):

Broadband

In general, broadband refers to many types of Internet-access options. For instance, fixed options include: fiber-optic, cable, DSL and satellite.

Mobile-broadband options require a contract with a cellular company to connect to the Internet by means of a router, a PC card or another adapter installed on your laptop. However, you will need to be in an area with good cellular coverage, so be sure to check with your local cellular provider. Personally, whenever I'm on the go, I use my BlackBerry as a modem to connect to the Internet. And, to ensure your coverage is reliable, some providers even offer a 30-day trial.

Fiber-optic

Internet providers also have fixed-broadband options. So, what's the advantage of a fiber-optic connection? In a phrase: lighting-fast speed. Verizon Wireless is the most popular provider of this relatively new service, which can be bundled with other services such as cell/home phone and television.

DSL

High-speed DSL, or Digital Subscriber Line, is one of the most common ways to access the Internet. Data is sent over local telephone lines using high-frequency waves, so it doesn't interfere with telephone use. In addition, filters are installed on each phone jack so that low frequencies (human voice tones) are distinguished from the high-frequency data being transmitted by your computer. Hint: Picture a four-lane highway. Also, if you don't have a landline phone, standalone DSL lines are also available.

Cable broadband

This service is available where cable-television services are offered. One advantage of this technology? Customers with this type of ISP can simultaneously watch television and access the Internet. These ISPs often bundle their services together, enticing customers to subscribe to all-in-one Internet and cable television services. However, one drawback to this type of connection is that providers can limit your connectivity based on how much access you've utilized. They can also cap off your usage similar to how a cell phone company charges you if you go beyond a certain number of minutes. Because of this, it's important to read through your contract carefully.

Satellite broadband

When all other options are exhausted, satellite broadband may suffice. Bear in mind: If satellite services are available in your area, you can still access the Internet. However, there are obvious disadvantages to satellites. For instance, speed is reportedly slower than with other options, and physical interference, such as woods, may hinder equipment installation. Also, satellite companies tend to limit the total use of data transmission and Internet access - so again, be sure to read the contract details carefully.

A Speedy Solution

Unless you're still stuck on dialup, Internet connections should be pretty fast - a few seconds or less to load a webpage. If you have access to fiber-optic in your office or home, then that's certainly your best - and speediest - bet. Subsequently, if cable is available in your area, then it may be a better option than DSL.

In addition, bundling services together, such as home/cell phone, TV and Internet, may save you money. However, keep in mind that if you ever consider dropping your provider, you'll also have to stop the other services that they provide.
