Computer Science for IGCSE & O level - Data Transmission (Section 3 - No. 5)
Which of the following is/are features of serial data transmission?
Data is sent one bit at a time.
Often used for long-distance transmission.
Requires multiple wires.
Generally slower than parallel transmission.
Explication
Serial data transmission sends data sequentially using one wire (or one pair of wires for differential signaling).
