![]() ![]() (2) A socket on a computer used to connect a printer or other device via a parallel interface (eight data bits transferring simultaneously). A parallel port sends data by sending multiple bits in parallel fashion. A serial port sends data bit by bit after sending a bit at a time. A parallel port is able to transmit multiple data streams at a time. ![]() What is the difference between serial port and parallel port?Ī serial port is able to transmit a single stream of data at a time. They replace long-running analog interfaces like VGA, S-video, and RGB. The High Definition Multimedia Interface (HDMI) and DisplayPort are both modern serial interfaces for carrying digital video from one product to another over cables. With the introduction of USB, FireWire, and other faster solutions, parallel ports are rarely used anymore. Below is an example of the DB25 interface found on the back of the computer. ![]() The parallel port is found on the back of the computer and is part of the motherboard. Check to see if the parallel ports and parallel device is listed under Ports (COM & LPT). ![]() When you test the parallel ports and parallel device, it is recommended that you do the following: Press the Windows key + R, type devmgmt. Later versions allow bi-directional communications. A parallel port has multiple connectors and in theory allows data to be sent simultaneously down several cables at once. The most common parallel port is a printer port known as the Centronics port. Type Point-to-point Production history Designer Centronics, IBM Designed 1970–1981. A DB-25 connector often used for a parallel printer port on IBM PC compatible computers, with the printer icon. In computing, a parallel port was a type of interface found on computers (personal and otherwise) for connecting peripherals.Parallel port.
