Choosing a modem

When selecting a modem, look for one with fast data-transfer speed, a compatible modem cable, and good bundled software.

Data-transfer speed

The data-transfer speed determines how fast a modem can move data between your computer and other computers. Purchase the fastest modem that you can afford, particularly if you plan to connect to the World Wide Web. Many Web pages contain graphics, video, and sound files that will take longer to download (copy onto your computer) with a slower modem.

The data-transfer speed of a modem is specified in kilobits per second (kbps) or bits per second (bps). Faster modems transfer data to and from your computer more quickly than slower ones. The following table describes the current modem speeds that are available.

Modem speed	Usage
33,600 bps	The fastest modem available (as of this writing) for use with standard
(33.6 kbps)	analog telephone lines. Suitable for World Wide Web use.
28,800 bps	Slightly slower than a 33.6 kbps modem, but still very suitable
(28.8 kbps)	for World Wide Web use.
14,400 bps	Only half as fast as a 28.8 kbps modem. May be acceptable for
(14.4 kbps)	text-oriented applications such as e-mail or terminal emulation.
9600, 4800,	Too slow for most purposes.
and 2400 bps

Modem cable

If you purchase a modem that is designed for use with a Macintosh, it will probably include a Macintosh-compatible modem cable. If you have to purchase a cable separately, make sure it supports hardware handshaking, a protocol that controls the flow of data between computers. Also, check to make sure the cable has a rounded connector that will fit the modem port on the back of your computer (labeled with a W icon). A cable designed for use with a Windows- or DOS-compatible computer won’t work with your Macintosh.
