What type of connection is typically associated with older keyboard devices?

• A. USB
• B. HDMI
• C. PS2
• D. Ethernet

Answer: (C)

The connection type typically associated with older keyboard devices is the PS/2 connection. This round connector was commonly used for connecting keyboards and mice to computers before the widespread adoption of USB interfaces. PS/2 ports are distinct due to their two ports: one for the keyboard (usually purple) and one for the mouse (usually green). PS/2 connections have several characteristics that made them suitable for older computing systems. They provide a direct connection to the motherboard, allowing for lower latency and direct communication without the need for drivers in many cases. This reduced the complication of installing devices, making it easier to plug in a keyboard and have it work immediately. In contrast, USB connections, while now the standard for most keyboard devices, became popular later and are less commonly seen on older computers. HDMI is primarily used for video and audio transmission, and Ethernet is used for network connections, not for connecting input devices like keyboards. Thus, PS/2 remains the clear identification for older keyboard connections.
