2.11 – Connecting External Devices
Connecting external devices to the motherboard is an easy task. The standard devices you
should expect to plug into the motherboard are keyboards, mice, and printer cables. The
following diagram will detail the ATX port stack for the following board:

Parallel Port
Besides being used primarily to connect printers, the Printer Port is also used for devices such
as Zip drive, some external CD-RW drives and or other external devices. More on the
uncommon side these days are the Serial Ports. They were primarily used to connect external
modems, but most modems today are using USB or are installed internally.
TIP:
While the ports have been created to accept connectors in only one direction, make sure
to be careful when inserting connectors. At times, attaching connectors in the incorrect
orientation can damage, bend and or break the pins.
2.12 – Installing the Power Supply
