USB 1.1

USB (Universal Serial Bus), developed by a consortium including Intel, Microsoft, and others, evolved from version 1.0 to 1.1 in 1998, with a speed of 12 Mbps. Despite the slower speed, USB 1.1 found widespread use in computer peripherals. Its 5V supply voltage simplified device connections, making it a convenient and universal interface. Despite the 12 Mbps speed, USB 1.1 provided a reliable and widely compatible connection method, laying the foundation for modern USB technology.
