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.
[edit] 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.
