Computer Network Fun Review 5 - Data Link Layer

The network between 2 nodes is

• cable

• link

• physical layer

The data link layer is located between:

• application layer and transport layer

• transport layer and network layer

• network layer and physical layer

The data link layer of sending node needs to

• encapsulate the datagram/packet

• decapsulate the datagram/packet

• release the datagram

The data link layer of receiving node needs to

• encapsulate the datagram/packet

• decapsulate the datagram/packet

• release the datagram

The services that is provided by the data link layer is

• frame

• framing

• framed

ARP (Address Resolution Protocol) is working at

• data link layer

• network layer

• physical layer

• application layer

Frame contains

• Header, data packet and trailer

• Tail, data packet and header

• Data packet, head, trailer

Components in Header of a frame:

• Header, data packet and trailer

• Packet, head, trailer

• Start of frame, address, type/length

Components in Trailer of a frame:

• Packet, head, trailer

• Start of frame, address, type/length

• FCS/Frame check sequence and Stop Frame

Communication at data link layer is

• node to node

• router to router

• server to server

• coast to coast
