What is the primary function of Universal Serial Bus (USB) ports?

• A. To connect only power-intensive devices
• B. To allow easy connection of various external devices without rebooting
• C. To connect devices exclusively for video output
• D. To provide internet connectivity

Answer: (B)

The primary function of Universal Serial Bus (USB) ports is to allow easy connection of various external devices without rebooting. USB technology enables a wide range of devices, including keyboards, mice, printers, and external storage, to be connected and disconnected while the computer is running. This hot-swappable capability simplifies the user experience by allowing quick connections or disconnections without the need for restarting the system or powering it down, making it versatile and efficient for everyday use. The other choices do not capture the full functionality of USB ports. While USB can indeed supply power to devices, it is not limited to only power-intensive devices; it connects a multitude of peripherals and accessories. USB ports also serve to transmit data between devices, not exclusively for video output or internet connectivity, which would pertain to specific types of connections like HDMI for video or Ethernet/Wi-Fi for internet. Thus, the versatility and ease of use in connecting various external devices is what defines the primary function of USB ports.
