What is parallel port example?
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.May 19, 2015
What Colour is parallel port?
magentaThe parallel jack is often color-coded magenta. A standard parallel cable plugs into that jack and has a "traffic island" jack that plugs into parallel devices, such as inkprint printers. A parallel port is also known as LPT1 .
How do you identify a serial and parallel port?
The main difference between a serial port and a parallel port is that a serial port transmits data one bit after another, while a parallel port transmits all 8 bits of a byte in parallel. Thus a parallel port transmits data much faster than a serial port.

What is parallel cable?
A series of metal wires that enable multiple bits of data to be transferred simultaneously. Parallel cables have mostly given way to serial cables, where data is transferred one bit after another.
Is USB a parallel port?
Unlike a parallel port, which can connect one device at a time, USB ports can support additional devices with an external USB hub. A USB hub is plugged into a USB port on the computer and provides additional USB ports.
Is Ethernet serial or parallel?
Modern Ethernet is actually parallel.
