Question 3

Please briefly describe the following three ways of connecting to the Internet: Cable Internet service, digital subscriber line, and dial-up Internet service.

Accepted Answer

- Cable Internet service is a means of distributing broadband Internet access over the same infrastructure that offers cable television service. Local and national cable companies offer cable Internet service for a monthly subscription. Of all Internet services, cable Internet currently offers the fastest access speeds. Cable Internet service uses a cable modem to transfer data from your computer to your home cable connection and then to the Internet. 
- DSL (digital subscriber line) is a broadband, Internet access technology that works over standard phone lines. It offers fast, affordable connections. DSL is available from local telephone companies and third
-party DSL providers. DSL services can be symmetrical or asymmetrical. If you need lots of upstream speed, a symmetrical DSL connection could be the best choice. 
- Dial
-up Internet service uses a voiceband modem and telephone lines to transport data between your computer and an ISP. The modem converts digital data that originates on your computer into an analog signal that can travel over the same frequencies as voices carrying on a telephone conversation. Many ISPs offer dial
-up Internet access for less than U.S.$10 per month. Access speed is slow, and even downloading software and operating system updates can take hours on a dial
-up connection.
