What is High Speed Internet (DSL) service?


DSL, or “Digital Subscriber Line,” is a service that utilizes existing telephone lines to bring Internet to customers in their home or office. Unlike dial-up Internet service, DSL service doesn’t occupy the user’s phone line while he or she is online. That means that the user can make phone calls and be online simultaneously.

The DSL modem is what makes this possible. According to Merriam-Webster, a DSL modem “splits transmissions into two frequency bands: the lower frequencies for voice (ordinary telephone calls) and the upper band for digital data, especially for connection to the Internet.”

How fast is High Speed Internet (DSL)?

DSL speed is significantly faster than dial-up Internet. Dial-up Internet was one of the first Internet services available. It transfers data at very slow speeds. Compared to dial-up, DSL service is high-speed Internet. It was one of the first high-speed Internet services available to users.

Unlike dial-up, DSL is always on. Previously, users of dial-up would have to manually dial in to the Internet any time they wanted to use it. Having “always on” DSL significantly reduces waiting time for users, who can get more done online with high speed DSL than they could with dial-up.

High Speed Internet (DSL) vs. Cable Internet: Which should you choose?

DSL poses several advantages over cable Internet. With DSL, users get a dedicated line straight from the provider to their home or office computer. That means they don’t have to share DSL speed with neighbors. Customer satisfaction is high among DSL users.

Cable users, on the other hand, have to share an Internet connection with their neighbors. Sometimes up to 500 users share the same Internet connection. This can greatly reduce cable Internet speeds, especially during hours of high Internet usage.

High Speed internet (DSL) vs. Satellite Internet: Which should you choose?

DSL Internet is often available to users living in urban or suburban areas. Alternatively, satellite Internet was developed to provide a high-speed Internet connection to those living in rural areas, where other forms of high-speed Internet aren’t always available.

DSL is significantly less expensive than satellite Internet. Satellite Internet can be much more expensive, depending on the package you select and the ISP you choose.

Also, satellite Internet speeds tend to be slower than DSL speed. That’s because a satellite Internet signal has to travel from the satellite in space to a user’s computer. DSL signals, on the other hand, only have to travel from the provider to the user’s computer over their existing phone line.
