Use the 25-hole parallel connector to attach a parallel device to the
computer. The parallel connector is used primarily for printers. The parallel
connector transmits data in parallel format, where 8 data bits (one byte) are
sent simultaneously over eight separate lines.
The parallel connector can also be configured for compatibility with the
PS/2 standard. Support for the EPP feature improves network adapter
performance (adapters connect to the computer's parallel connector and
require the appropriate software drivers from the adapter's manufacturer).
If you reconfigure your hardware, you may need pin number and signal
information for the parallel connector.
Use the 6-hole, miniature DIN PS/2 connector to attach PS/2-compatible
devices such as a mouse, keyboard, or external numeric keypad. If you
reconfigure your hardware, you may need pin number and signal
information for the PS/2 connector.
Use the USB connector to attach one or more USB devices, such as a
mouse, to the computer. USB is a peripheral standard that enables
automatic detection of USB-compliant peripheral devices.
