What is the maximum transfer rate of USB 1.1?

The maximum transfer rate of USB 1.1 is indeed 12 Mbps. This version of USB (Universal Serial Bus) was introduced to provide a faster alternative to the previous USB 1.0 standard, which had a maximum speed of 1.5 Mbps.

USB 1.1 improved the standard by increasing the transfer speed significantly, allowing for better performance with peripherals such as mice, keyboards, and printers. It's important to remember that while it was a major advancement at the time, USB technology has continued to evolve over the years, leading to much faster standards such as USB 2.0, which has a maximum transfer rate of 480 Mbps, and USB 3.0 and later versions, which offer even higher speeds.

In this context, options representing speeds of 480 Mbps, 1.5 Mbps, and 5 Gbps refer to later USB specifications, while the 12 Mbps rate accurately reflects the capability of USB 1.1.
