(2) A socket on a computer used to connect a printer or other device via a parallel interface (eight data bits transferring simultaneously). In the past, the parallel port was widely used for ...

[Fernando] wrote in to share his take on building a logic analyzer. He’s using the parallel port to capture data and feed it to the display software of your choice. The method depends on a ...

The circuit uses a HC245 octal bus transceiver to feed the 8 data lines on the parallel port. (You can use a variety of chips for this application, most CMOS buffers will probably be fine.) ...

Because there was only one serial and one parallel port on the computer, the key acted as a pass-through so that other keys and peripheral devices could connect. In fact, the nickname "dongle" was ...
