USB-Ports: Die wahre Bedeutung der Farben hinter dem Standard

Did you know that the color of a USB port is commonly an indicator of both its speed and features? White is for USB 1, which was introduced over 30 years ago, enabling hot plug as well as the ability to connect a wide variety of different devices to one simple port. But it was pretty slow. And that's where Black came in. That's USB 2, which can do up to 480 megabit per second. Perfect for your low- speed peripherals or your old MP3 player. Not great for high resolution video. And that's where the world turns to color with blue USB 3 5 GB per second ports. Moving on to teal. These are often accompanied by a little 10 next to the port that indicates, you guessed it, 10 Gbits per second. Red or yellow often indicate a port that still provides power even when your device is asleep for convenient charging. And as for green and purple, that's just manufacturers breaking the rules.
