What is the maximum data transfer rate for USB 2.0?
- 120 Mbps
- 480 Mbps ✓
- 5 Gbps
- 10 Gbps
Correct answer: 480 Mbps
USB 2.0, also known as Hi-Speed USB, has a maximum theoretical data transfer rate of 480 Mbps (megabits per second), a specification established in the USB 2.0 standard released in 2000. Option A is incorrect because 120 Mbps does not correspond to any standard USB specification; the predecessor USB 1.1 Full-Speed topped out at 12 Mbps while USB 2.0 is 480 Mbps. Option C is incorrect because 5 Gbps is the transfer rate of USB 3.0 (also called USB 3.1 Gen 1 or USB 3.2 Gen 1), which is a full generation beyond USB 2.0. Option D is incorrect because 10 Gbps corresponds to USB 3.1 Gen 2 (also called USB 3.2 Gen 2), two generations newer than USB 2.0.
