The popular USB (Universal Serial Bus) standard for connecting computer peripherals uses Manchester encoding

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.
