DSL Modems Key Terms

Learn the terminology you need to know about DSL modems

If you want a fast Internet connection, but can't afford a T1 connection, then it's a good idea to purchase DSL from an ISP provider. DSL stands for digital subscriber line and a DSL modem is what you use to connect to the Internet. There are many different types of DSL modems and supplies, which can make it difficult to know what you need. Many Internet service providers will give you a DSL modem for free as part of their service. However, in most cases, you can choose to purchase a third party DSL modem if you feel that you need a better performance. Learn the following terms related to DSL modems in order to make the right choices.

Wireless DSL modem

A wireless DSL modem is just as it sounds, a DSL modem that does not require wires to connect to the Internet. This can be a big convenience when you are working in an office where many computers need to connect to the Internet.

ADSL, RADSL, SDSL and IDSL

Asymmetrical digital subscriber line (ADSL), rate adaptive digital subscriber line (RADSL), symmetric digital subscriber line (SDSL) and ISDN digital subscriber line (IDSL) are all different types of DSL connections. With ADSL, your download rate is faster than your upload rate, while with SDSL, the rates are the same. RADSL adapts based on the fastest connection available. IDSL uses IDSL technology for DSL service.

Router

A router allows one DSL modem to provide access to several computers. This is ideal in small office situations. Routers can also provide an extra level of security.

Cat 5 or Ethernet cable

The category 5, or cat 5, cable is often referred to as an Ethernet cable. This is the cable that connects your DSL modem to the computer.

Upload and download speed

The upload speed refers to how quickly you can upload data from your computer to the Internet, while the download speed refers to how quickly you can download information. Many companies primarily use the download feature and these rates are often faster.

DSL modem security

All computers are subject to attacks by viruses and malicious software. Using DSL modem security measures, you can reduce the amount of risk to your computer.
