What are the key functions of encapsulation? (Choose three.)allows modification of the original data before transmission.identifies pieces of data as part of the same communication.enables consistent network paths for communication.ensures that data pieces can be directed to the correct receiving end device.enables the reassembly of complete messages.tracks delay between end devices.4.
