👉 Desktop I/O, or D-I-O, refers to the method of connecting a computer's peripherals—such as keyboards, mice, printers, and external storage devices—to a computer via a dedicated cable rather than using a standard USB or Ethernet connection. This setup typically involves USB-C, Thunderbolt, or USB-A ports on the computer paired with a corresponding D-I-O cable, allowing for faster data transfer rates, more power delivery, and often additional features like video output. D-I-O connections enhance performance and flexibility, making them ideal for tasks requiring high-speed data transfer, such as gaming, video editing, and professional workflows, while also simplifying cable management within the workspace.
