Which of the following technologies typically uses USB connections?

USB (Universal Serial Bus) connections are commonly used for a wide variety of peripherals that require powered connections or data transfer with a computer. Printers and keyboards are classic examples of devices that rely on USB technology. They utilize USB ports for direct connectivity to computers or other devices, facilitating the transfer of instructions, data, and power.

Printers use USB connections to receive print jobs from computers, making it easy to set up and operate. Keyboards likewise connect via USB, enabling users to input data easily. These connections are standardized, which paves the way for interoperability among different devices and manufacturers.

While televisions, wireless routers, and smart home devices may sometimes feature USB ports for specific functions (like software updates or power), they are not primarily connected through USB for their main operational use. Instead, they often rely on other types of connections like HDMI for televisions, Ethernet or Wi-Fi for routers, and various proprietary connections for smart devices, making printers and keyboards the more definitive examples of devices that typically use USB connections.
