  1. Data link layer

    The network interface layer, commonly referred to as the data link layer, is the physical interface between the host system and the network hardware. It defines how data packets are to be formatted for transmission and routings. Some common link layer protocols include IEEE 802.2 and X.25.

    What are the four main processes at the network layer?
    • Addressing end devices – End devices must be configured with a unique IP address for identification on the network.
    • Encapsulation – The network layer encapsulates the protocol data unit (PDU) from the transport layer into a packet. ...
    • Routing – The network layer provides services to direct the packets to a destination host on another network. ...

    What does the network layer do?

    The Network Layer of OSI Model

    • It is responsible for routing packets from the source host to the destination host. ...
    • The data link layer assigns the physical address locally. ...
    • This layer also provides mechanisms for congestion control.
    • The network layer tackles issues like transmission delays, transmission time, avoidance of jitters, etc.

    What services does the network layer provide?
    The network layer is the third layer of the internet model. It receives services from the data link layer and then provides services to the transport layer of the model. The network layer provides mainly these services, the internetworking, the addressing, the routing, the packetizing, and the fragmenting.

    What is the network layer responsible for?

    The seven layers of the OSI model are:

    1. Physical layer: Packets are converted into electrical, radio, or optical pulses and transmitted as bits (the smallest possible units of information) over wires, radio waves, or cables.
    2. Data link layer: Handles communications between devices on the same network. ...
    3. Network layer: Handles the routing and sending of data between different networks. ...
