The table contains descriptions about data transmission methods. Complete the table by identifying which data transmission methods are described. Data transmission method Description Data is transmitted down a single wire, one bit at a time, in one direction only. Data is transmitted down multiple wires, multiple bits at a time, in both directions, but only one direction at a time. Data is transmitted down a single wire, one bit at a time, in both directions at the same time. Data is transmitted down multiple wires, multiple bits at a time, in one direction only.

Data is transmitted down multiple wires, multiple bits at a time, in both directions, but only one direction at a time. Data is transmitted down a single wire, one bit at a time, in both directions at the same time. Data is transmitted down multiple wires, multiple bits at a time, in one direction only.[4]
Mark scheme
Marking points from the official mark scheme (Oct/Nov 2023). The mark or mark type is shown in brackets.
- [4] One mark for each correct data transmission method: // Data transmission method: serial simplex, Description: Data is transmitted down a single wire, one bit at a time, in one direction only. // Data transmission method: parallel half-duplex, Description: Data is transmitted down multiple wires, multiple bits at a time, in both directions, but only one direction at a time. // Data transmission method: serial full-duplex, Description: Data is transmitted down a single wire, one bit at a time, in both directions at the same time. // Data transmission method: parallel simplex, Description: Data is transmitted down multiple wires, multiple bits at a time, in one direction only.
