Standards Comparison

These charts line up standards whose model numbers and version labels give little away. You can compare LAN cables (Cat5e to Cat8), Wi-Fi (802.11a to Wi-Fi 7), and USB (1.1 to USB4 2.0) on speed, supported distance, and how to tell them apart, and see how symbol keys shift between US and JIS keyboard layouts. Useful groundwork before buying hardware or planning cabling.
