  • (i) serial I/O
  • (ii) parallel 1/0
  • (iii) Both (i) and (ii)
  • (iv) Neither (i) nor (ii)

Correct option: (iii) Both serial and parallel I/O

Note: Question prints intradata due to typo; read as intra-data / data transfer.

The I/O subsystem can transfer data either:

  • Serial I/O - one bit at a time over single line, or
  • Parallel I/O - multiple bits simultaneously over parallel lines.

Modern interfaces support both. Hence option (iii) is correct.
