Bandwidth

Internet bandwidth (the speed at which your computer can send and receive information) is measured in either Kbps (kilobits per second) or Mbps (megabits per second). If you are lucky enough to have multiple broadband options in your area, compare these factors:


• Downstream bandwidth. This is the speed with which your computer can receive information from the Internet. The higher the downstream bandwidth, the faster your computer can display Web pages, transfer music, and download files. For most people, downstream bandwidth is more important than upstream bandwidth, so the speeds tend to be much higher. For example, a cable modem service might offer 6,000 Kbps downstream and only 768 Kbps upstream.

• Upstream bandwidth. This is the amount of data your computer can send to the Internet. This isn't important if you just plan to read e-mail and surf the Web, because your computer only needs to send a small request in order to receive a large Web page or e-mail. However, if you're into online gaming or you want to send large files to people, then higher upstream bandwidth is important, and you should choose the highest upstream bandwidth available.

• Reliability and customer service. ISP reliability has increased significantly in recent years; however, it is still not as reliable as your phone or television service. There is no objective way to measure reliability and customer service, so you should talk to your neighbors about their experiences and search the Web for reviews of ISPs in your area.
