Choose a CORRECT statement on the Ethernet technology. Switches do not regenerate arrived signals in their shapes and strengths. The LLC sub-layer header describes the type of packet contained in the frame's data field. Ethernet switches utilize CSMA/CD to control network access. It is generally OK for office workers to install hubs or switches in their office because this does not affect overall network performance. Most switches rely on the half-duplex mode of data transmissions.
