The speed of your modem (e.g. 56,600 baud) represents the speed at which
the modem is capable of transmitting information. A modem with a speed
of 56,600 baud means that the modem can transmit 56,600 bits (not bytes)
per second (bps). Your modem may be capable of faster speeds of transmis-
sion from modem to computer. This does not affect the rate of communica-
tion between modems, but, if both modems are capable of such compres-
sion, a connection can have a higher effective speed if the sending system
compresses the data as it is sent from the sending computer to the sending
modem and if the receiving system decompresses the data as it is sent from
the receiving modem to the receiving computer. Thus, it is possible to
“connect” at higher speeds. You should always try to connect at the highest
rate of connection available to you. The modems will negotiate the connec-
tion and establish the actual rate of transmission of information (the key is
the compatibility of the modems—the standards in this industry are fairly
well-established and thus compatibility is pretty much the norm).
To connect to anything with your modem,
you will usually need to sign on with some
provider (unless you have log-in rights with
some network already—e.g. at work) or dial-
in to another computer already set to receive
such connections. On-line service providers
will allow you to connect to an extensive
computer environment. You can use such
providers to send and receive email (elec-
tronic mail), chat with other computer users,
look up information in their databases, par-
ticipate in electronic discussions with multi-
ple parties, and even download software. The
major service providers usually charge a
monthly fee for connection time. Some ser-
vices they provide may entail an additional
charge. Since such electronic connections are
an important resource for computer users,
