Show answer & explanation
Correct answer: C
Key formulas: total cables = n × (n - 1) / 2; ports per device = n - 1.
Compute total cables for n = 10: 10 × 9 / 2 = 45 cables.
Compute ports per device: each device connects to the other 9 devices, so 10 - 1 = 9 ports per device.
Final answer: 45 total cables and 9 ports for each device.
