A lot
could be said about modems. I'll keep it short.
If you want
to connect to the WWW, you'll need one of these in one form or
another. Currently the most popular is the "dial-up" or telephone
type modem, that uses the same lines as telephones. Of these there
are two primary types.
First, the software modem, also called a
"Win Modem" These modems depend heavily on the CPU for their
operation. On low-end systems you might notice a drag on the system
during dial-ups or while downloading. The upside is that they are
considerably less expensive.
Hardware modems are more expensive,
but are far less taxing on the system resources.
Other
considerations: There are internal and external modems, internal
being the most popular by far. There are ISA modems (slower) and PCI
modems (faster).
Then there are many much faster
options. I am very fond of the idea of satellite type connections
(like DirecTV's Direct
DSL. It's super fast and
doesn't tie up the phone line. It's also somewhat pricey. |

 V.90 is the old standard, The next new thing is
V.92 It has muy mucho bells and whistles! The bad news is that
many ISP's don't support it yet.
NICs
Network
Interface Cards (NIC) are used to connect PC's to one another through a
network. Even though the port looks like a phone line type port,
it's not. The "phone" type port is called an RJ-11,
and the NIC port is an RJ-45,
and they are not interchangeable.
Networking PC's makes some cool
things possible, like sharing one dial-up connection, or sharing
printers. There are also wireless networking options, but make sure
there are sufficient funds in your checking account!
