Q1. What does "USB" stand for?
Explanation
USB stands for Universal Serial Bus, the standard interface used to connect devices such as keyboards, pen drives, printers, and cameras to a computer. Universal Series Bus is incorrect because "series" is not the standard term in this abbreviation. Universal Sequential Bus is also wrong; USB communication may involve serial transfer, but "sequential" is not part of the name. Uniform Series Bus is a fabricated expansion and is not used in computer terminology.
