What is the purpose of a parallel port?
A parallel port is an interface allowing a personal computer (PC) to transmit or receive data down multiple bundled cables to a peripheral device such as a printer. The most common parallel port is a printer port known as the Centronics port.
Why do motherboards have serial ports?
An asynchronous port on the computer used to connect a serial device to the computer and capable of transmitting one bit at a time. Serial ports are usually identified on IBM compatible computers as COM (communications) ports. For example, a mouse might connect to COM1 and a modem to COM2.
What is a PC parallel port?
See parallel interface. (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past, the parallel port was widely used for printers and occasionally for connecting other devices externally, but was superseded by USB.
What is the use of 25 pin parallel port?
On PCs, the parallel port uses a 25-pin connector (type DB-25) and is used to connect printers, computers and other devices that need relatively high bandwidth. It is often called a Centronics interface after the company that designed the original standard for parallel communication between a computer and printer.
Which devices can be connected to parallel port?
Other uses included optical disc drives such as CD readers and writers, Zip drives, scanners, external modems, gamepads, and joysticks. Some of the earliest portable MP3 players required a parallel port connection for transferring songs to the device. Adapters were available to run SCSI devices via parallel.
What devices can we plug in a parallel port?
What are the serial and parallel motherboard ports used for?
Serial ports were basically developed for devices that didn’t require speed such as mice and keyboards, while parallel ports were used for devices that needed data to be processed much faster , like printers. The ancient DB 9 serial port has long been obsolete, but many motherboards still have PS 2 ports for a mouse and keyboard.
How many serial ports on a motherboard?
6 Serial ATA ports (version 3.0 SATA) It also has an integrated network adapter, an integrated sound chip, a VGA display output, and a whole host of other timing and controlling systems. Other motherboards will have more basic/advanced chipsets (providing more PCIe lanes, for example) but in general, most chipsets offer the same kind of features.
Is a parallel port a type of computer port?
What is a parallel port in computer?
Definition of: parallel port (1) A hardware interface that transfers one or more bytes simultaneously. See parallel interface. (2) A socket on a computer used to connect a printer or other device via a parallel interface (eight data bits transferring simultaneously).
