Solution

The statement is incorrect. The USB (Universal Serial Bus) standard does not use Manchester encoding for connecting computer peripherals. Instead, it uses a form of encoding known as NRZI (Non-Return to Zero Inverted).

Manchester encoding is a type of digital encoding in which the presence of a data bit is indicated by a transition rather than a level. This encoding is used in some forms of data communication, but not in USB connections.

On the other hand, NRZI encoding, used by USB, is a method of changing and encoding data bits that are being sent over a network. In NRZI, a change in the level of the signal denotes a '0', while no change denotes a '1'. This is different from Manchester encoding where a transition in the middle of the bit period represents a '0' and no transition represents a '1'.

So, in summary, USB uses NRZI encoding, not Manchester encoding.
