What is an advantage of parallel transmission?

Parallel transmission involves sending multiple bits of data simultaneously across multiple channels. This significantly increases the amount of data that can be transferred at one time, making it much faster than serial transmission, where data is sent one bit at a time. The ability to transmit several bits simultaneously reduces the overall time required to send a larger amount of data, thus enabling faster data transfer rates.

In contrast, cheaper cabling is typically associated with serial transmission systems because serial cables require fewer wires than parallel cables, which can also contribute to the ease of installation. Better signal quality over long distances is more applicable to serial transmission due to its reduced interference and the advantages of single-channel transmission over distances. Finally, parallel transmission often requires more power to operate, as multiple channels need to be powered for simultaneous data transfer.
