Match each type of frame field to its function. (Not all options are used.)

1. Addressing: This field is responsible for directing the frame toward its destination. In an Ethernet frame, this would correspond to both the source and destination MAC addresses.
2. Error detection: This field checks if the frame has been damaged during the transfer. This corresponds to the Frame Check Sequence (FCS) at the end of an Ethernet frame.
3. Type: This field is used by the Logical Link Control (LLC) to identify the Layer 3 protocol, such as IP. It can indicate what type of payload the frame is carrying.
4. Frame start: This field identifies the beginning of a frame. In Ethernet frames, this is typically the preamble or the start frame delimiter (SFD).

Flow control services are typically managed at higher layers (like the transport layer in TCP with flow control mechanisms) and not indicated by a specific field in the Ethernet frame structure.
