Dial Up Connection
The most basic type of Internet connection is called a dial-up connection. This connection is made through a modem (the communication mechanism in computers) that uses a telephone line to connect to the Internet. The modem must dial the telephone every time it wants to connect to the Internet, hence the name dial-up connection.
The fastest modem that you can use for this type of Internet connection is called a 56K modem. When a regular analog telephone line is used for an Internet connection, the modem must convert the analog signals that it receives from the telephone line into digital signals that the computer can comprehend. To send information from your computer, the modem must take the computer’s digital signals and convert them into analog signals to be sent over the telephone line. All of these conversions take time; compared to other Internet connections, this is a relatively slow connection. One other problem with this type connection is that calling the Internet will tie up your telephone line often forcing frequent users to bear the cost of installing and paying the monthly fees for a second telephone line.
Satellite/Wireless Connection
Satellite (HST) This is the most expensive alternative for getting a high-speed connection to the Internet. If you live in a rural area or a spot where other options are not available (as I do), then this is probably your only hope for a high-speed connection. These come in two varieties, 1-way and 2-way. One-way satellites are like television receivers: they only accept signals. You’ll still have to use your modem to connect for uploads. A 2-way connection, however, both sends and receives and is telephone-free.
Average speeds for this type of connection are 600K and higher for download and 128K for the upload. Averages tend to be higher because there are far fewer users on the network to slow things down. The biggest up side to this technology is that it is available just about everywhere. The biggest downside to this type of connection is two-fold: price and reliability. Expect to spend $600 or more for the equipment and another $50 or more a month for the connection. You’ll also experience down time (which will not be reimbursed by the ISP) during severe weather (called “rainouts”). Most satellite providers provide a dialup backup service as a part of their plan.
