Computer Science for IGCSE & O level - Data Transmission (Section 9 - No. 43)
What is the main difference between parallel and serial data transmission?
Parallel uses one channel, while serial uses multiple channels.
Parallel transmits bits simultaneously, while serial transmits bits sequentially.
Parallel is slower than serial.
Serial is used for longer distances.

The primary difference lies in how the bits are transmitted. Parallel sends multiple bits concurrently; serial sends them one after another.
