Parallel transmission

Parallel transmission

In telecommunication, parallel transmission is:

# The simultaneous transmission of the signal elements of a character or other data item.
# In digital communications, the simultaneous transmission of related signal elements over two or more separate paths.

Contrast with serial transmission

In computing, bit parallel transmission is the transmission of several bits at the same time, with each bit transmitted over a separate wire. An "8-bit parallel" channel transmits eight bits (or a byte) simultaneously. A serial channel would transmit those bits one at a time. If both operated at the same clock speed, the parallel channel would be eight times faster.

Several computer interfaces use or used parallel transmission: ATA or IDE interface, SCSI Parallel Interface (SPI; the traditional SCSI), and the parallel port.
