Mouse port
Attach the mouse that comes with your computer to this
port. The mouse port supports a PS/2-compatible
mouse.
„
Universal Serial Bus ports
The Universal Serial Bus (USB) ports allow you to add
new plug and play serial devices without opening up the
system. You simply plug the devices into the ports. The
USB determines system resources for each peripheral
and assigns them without user intervention. Up to 127
devices can be daisy chained to a single USB port.
„
Fax/modem ports
Some systems come with a 56 kilobytes per second
(Kbps) fax/modem board. The fax/modem board allows
the connection of a phone line to the computer for fax
and data communications functions.
Dual fax/modem ports let you use a telephone line for
the fax/modem and your telephone.
The fax/modem board uses x2 technology. x2 products
are capable of 56 Kbps (52 Kbps in the U.S.). However,
the download speeds you experience may go lower due
to varying line conditions. Uploads from end user to
service provider travel at speeds up to 28.8 Kbps. An
x2-compatible analog phone line and an x2-capable
service provider are required for high-speed downloads.
