(Choose two)

1. Data link layer adds physical source & destination address & an FCS to the segment
2. The presentation layer translated bits into bits into voltages for transmission across the physical link
3. Transport layer divides a data stream into segments & adds reliability & flow control information
4. Packets are created when the network layer encapsulate a frame with source & destination host address &
   protocol related control information
5. Packets are created when the network layers adds layers 3 address & control information to a segment
