Which connectors on the back of a computer are commonly used to attach a mouse to a modern PC system?

1. USB A; Mini-DIN

2. HDMI; VGA

3. COM; LPT

4. Ethernet; FireWire

The correct answer is: USB A; Mini-DIN

The chosen answer identifies the connectors that are most relevant for connecting a mouse to a modern PC system. USB ports, specifically USB A connectors, are widely used for peripheral devices like a mouse due to their versatility, ease of use, and universal compatibility across most computer systems. The Mini-DIN connector, which is traditionally associated with PS/2 mice, represents an older standard that some systems still support, although USB has largely replaced it. Other options do not relate to typical mouse connections. HDMI and VGA are primarily used for video output to monitors, so they would not facilitate mouse connections. Similarly, COM (serial) and LPT (parallel) ports are outdated interfaces primarily used for connecting older printers and devices, and are not suitable for modern mouse connections. Finally, Ethernet ports are used for networking, while FireWire is employed for high-speed data transfer, not for mouse connectivity. Thus, the identification of USB A and Mini-DIN correctly aligns with current common practices for mouse connections.
