9. Of the following, what do USB and FireWire connections have in common?

Both are used for connecting keyboards

Both support dual monitors

Both support hot-swapping devices

Both use D-subminiature connectors

USB and FireWire connections have in common the ability to support hot-swapping devices. This means that devices can be connected or disconnected without having to restart the computer or interrupt its operation. Hot-swapping is a convenient feature that allows for easy and seamless connection and disconnection of peripherals, making it possible to add or remove devices without causing any disruption to the system.
