The Story of Serial and Parallel Ports: The Ancestors of USB Before the universal USB ports we all know today, computers spoke through more primitive—but fascinating—channels: serial and parallel ...

I have been working with computers since the late 70s, and that's not for boasting purposes, but to tell you where I come from. When I started, I was always told to NEVER plug/unplug the following ...

This is just a general question. I know, obviously, that there are RS-232 "serial ports" and IEEE 1284/Centronix ports "parallel ports," and that these are "digital" connections. Then you have things ...

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 ...

Early microcomputers typically consisted of a half dozen (or more) circuit boards--plugged into a backplane--that implemented the central processor unit (CPU), memory, disk controllers and ...

Serial ports have been around since the earliest days of computing. Originally intended to connect devices like printers and modems to personal computers, they still exist today in some form or ...

Based on the modern Kernel-Mode Driver Framework (KMDF) instead of the legacy NT4 driver model, thereby correctly reacting to Plug&Play events concerning serial/parallel ports. Compatible with 64-bit ...

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 ...

The OXmPCI954 is designed to handle 15-Mbit/s asynchronous and 60-Mbit/s synchronous serial data rates. It integrates four high-performance UART channels, a 3.3-V PCI interface, and a local... The ...
