Motherboard Rear I/O Panel Explained - Port Functions & Layout #182517 (License: Personal Use)

This image displays a typical ATX motherboard rear I/O shield featuring legacy and early-2000s connectivity options: PS/2 keyboard/mouse, two USB 1.1/2.0 ports, dual RS-232 COM ports, line-in/line-out/mic audio jacks, an RJ-45 Ethernet port, a parallel printer port, and a 15-pin game port. The color-coded connectors (purple for keyboard, green for mouse, teal for COM, yellow for game port) follow standard PC conventions for user-friendly setup. Such layouts were common in mid-2000s consumer and business desktop motherboards before USB-C and integrated audio superseded many of these interfaces.
