Input/output device interfaces are used for which purpose?

• A. Power supply connectors
• B. Encryption protocols
• C. Common types of interfaces used for connecting input and output devices to a computer
• D. Networking standards

Answer: (C)

Input/output device interfaces are standardized connectors and signaling methods that let peripherals talk to a computer. They define how devices such as keyboards, mice, printers, displays, and external storage attach and how data moves between the device and the computer, sometimes including power delivery. This standardization enables plug-and-play compatibility, broad device support, and reliable communication across different manufacturers. Examples include USB, HDMI, DisplayPort, SATA, and PCIe. These interfaces are about connecting I/O devices, not about powering them (pure power connectors), securing data (encryption protocols), or networking over a network (networking standards).
