Which device typically has both Type A and Type B USB ports?

USB-compatible hub
Computer motherboard
External hard drive
Printer

The correct answer is: USB-compatible hub

A USB-compatible hub is designed to provide multiple USB ports for connecting various devices, and it typically includes both Type A and Type B USB ports. The Type A USB port is the most common connection, found on computers and many devices for data transfer and power supply, while Type B is often used for connecting peripherals like printers and external hard drives. Hubs are particularly useful in expanding the number of available USB connections, allowing users to connect multiple devices simultaneously. By having both types of ports, a USB-compatible hub ensures compatibility with a wider range of devices, making it versatile and essential for setups that require various USB connections. Other devices, such as computer motherboards, may have multiple USB ports, but they usually do not include Type B ports. External hard drives typically feature Type A or Micro-B ports for direct connections but do not generally provide the broader versatility of additional hub functionality. Printers mainly come with Type B ports to connect to computers but do not typically offer Type A ports for device expansion.
