ANSWER: The most obvious difference is size. The parallel port on the back of your computer is a 25-pin port, while the serial port has room for nine pins. But the real difference is in the way they ...

My X31 had a parallel port, and there was a serial port on the optional UltraBase. I've never seen the UltraBase in person, but I expect it makes the X31 one thick but tiny footprint beast. I think PC ...

So I'm trying to detect through Visual Basic 6.0 when a voltage change occurs on one of the pins of the serial/parallel port. The whole thing is pretty simple; no data transfer/handshaking/etc needs ...

This application note presents the process of converting a serial output into parallel output using common serial-to-parallel register integrated circuits. The document also discussed the CS556x/7x/8x ...

This converter may help if just the serial port on a personal computer is free, whereas the printer needs a parallel (Centronics) port. It converts a serial 2400 baud signal into a parallel signal.

While the average computer user likely hasn’t given much thought to the lowly serial port in decades, the same can’t be said for the hardware hacker. Cheap serial-to-USB adapters are invaluable for ...

Getting data to a storage medium requires transmission. Parallel transmission has historically been the preferred way to write data to disk. But at current speeds, serial transmission can be faster ...
