a) improve security for videoconferencing
b) compress data for isochronous transfers
c) ensure edge density to facilitate identifying bit fra"

Answer 1

Bit stuffing is a technique used in USB 2.0 to ensure edge density and facilitate identifying bit frames. It involves adding extra bits to a data stream to ensure a sufficient number of transitions between 0s and 1s.

Step-by-step explanation:

Bit stuffing is a technique used in USB 2.0 to ensure edge density and facilitate identifying bit frames. It involves adding extra bits to a data stream to ensure a sufficient number of transitions between 0s and 1s. This helps to maintain synchronization and detect errors in the transmission.

Bit stuffing is not used to improve security for videoconferencing or compress data for isochronous transfers. Instead, it is primarily used to maintain the integrity and synchronization of the data being transferred.
