The most common parallel port is a printer port known as the Centronics port.| Peter Jennings Here are some positive outcomes from the Chinese Communist Party’s descent into North Korean–style insult and abuse: Australians get to see firsthand the entity we are dealing with, and Beijing’s collection of local useful idiots … Peter Jennings: Australia has a tradition of producing what we call “defence white papers” every five years or so. A serial port uses Male ports.Ī 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. 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. In this way, what is the use of parallel port and serial port?Ī parallel port is able to transmit multiple data streams at a time. For electronics hobbyists the parallel port is still often the easiest way to connect to an external circuit board. When using a parallel port, the computer sends the data 1 byte at a time (8 bits in parallel, as opposed to 8 bits serially as in a serial port).įurthermore, are parallel ports still used? Current use For consumers, USB and computer networks have replaced the parallel printer port, for connections both to printers and to other devices. When a PC wants to send data to a printer, it sends it either through a parallel port, a serial port or a network connection.
These 8 bits are transmitted parallel to each other, as opposed to the same eight bits being transmitted serially (all in a single row) through a serial port.Īlso know, how does a parallel port work? When a PC sends data to a printer or other device using a parallel port, it sends 8 bits of data (1 byte) at a time.
