According to the University of Mexico, serial ports transmit data one bit at a time, whereas parallel ports transmit 8 bits of data at a time. The location of the port depends on the age and type of the device.
On older computers, serial ports are connected to a keyboard, modem or mouse; a parallel port is faster and is connected the printer. Newer computers use a wide range of ports to connect various hardware devices. The Universal Serial Bus, or USB port, is the most commonly used to connect devices such as an external drive, keyboard, scanner, mouse, printer or audio. Other commonly used ports are FireWire, Ethernet, PCMCIA, Audio Ports and SCSI.Learn More
Parallel transmission refers to a situation when binary data transfer occurs simultaneously, while serial transmission refers to one in which binary data transfer occurs one bit at a time. Parallel transmission is faster, but more complicated, because each bit travels along its own data path. Serial transmission is normally slower but simpler, because each bit shares a data path.Full Answer >
