ITPEC IP April 2018 Question 11
ITPEC IP April 2018 — Question 11 of 100
Both IEEE 1394 and USB support hot plugging, so compatible peripherals can be connected or disconnected while power is on. The interfaces are designed to detect device changes dynamically without requiring the entire computer to be shut down first.
Answer (a)
Why not others:
- their maximum transfer rates are not universally limited to 100 Mbit/s and vary by standard version
- users do not have to assign a unique ID manually to every connected device
- both are serial interfaces rather than parallel transmission over multiple data lines
Key rule: USB and IEEE 1394 are serial peripheral interfaces with hot-plug capability; their speeds and connection structures differ by version.
