Definition: The theoretical maximum data transfer rate of USB 2.0, equal to 480 megabits per second.
Explanation
480 Mbps refers to the maximum theoretical bandwidth of the USB 2.0 interface. This speed indicates how much data can be transferred per second over a USB 2.0 connection, measured in megabits per second (Mbps). In practical use, actual transfer speeds are lower due to protocol overhead and hardware limitations, but 480 Mbps remains sufficient for many applications such as streaming compressed 4K video on smart TVs.
Example
For example, a smart TV using a USB 2.0 port with a maximum speed of 480 Mbps can easily handle playing a 4K video stream encoded at 60 Mbps, since the required data rate is well below the USB 2.0 bandwidth limit.
Who This Is For
This term is useful for technology enthusiasts, smart TV users, and professionals interested in understanding USB interface speeds and their impact on media playback and device performance.
