<para>Cable connections are fast and reliable connections that users subscribe to

for a fixed monthly fee. Cable companies offer packages with different speed

specifications and bandwidth limits. If you travel and need Internet access, you
39
38
can purchase a wireless Internet connection. If your computer does not have one pre-installed,
40
39
you will need to install a wireless card. This connection is similar to a satellite connection, where data is

transmitted through the air. Dial-up access uses the same lines as your phone connection,

transmitted through the airwaves. Dial-up access uses the same lines as your phone connection,
42
41
except that the parties at the two ends are computers. This is a slow and cheap connection
43
42
that uses a phone line to connect to a local server. Your computer dials a phone number that is provided by your ISP and
44
43
connects to the server. Consequently, while you remain connected to the Internet,
46

using this mode can be very tedious and frustrating.</para>
