- 3. Data-Link layer The data link layer is the protocol layer in a program that handles the moving of data into and out of a physical link in a network. The data link layer is Layer 2 in the Open Systems Interconnection (OSI) architecture model for a set of telecommunication protocols. Data bits are encoded, decoded and organized in the data link layer, before they are transported as frames between two adjacent nodes on the same LAN or WAN. The data link layer also determines how devices recover from collisions that may occur when nodes attempt to send frames at the same time.
- 4. Data-Link layer Access to media Provides reliable transfer of data across media Transmits frames node to node based on station address

- 9. Physical addressing: Ethernet uses a 6-byte (46 bits) physical address that is imprinted on the network interface card (NIC). Ex: Most lan use a 48-bit (6 byte) physical address written as 12 hexadecimal digits, every byte (2 hexadecimal digits) is separated by a colon, As Shown below…. 07:01:02:01:2C:4B A 6 byte (12 hexadecimal digits) Physical Address.
- 10. Network Layer The network layer is the third level of the Open Systems Interconnection Model (OSI Model) and the layer that provides data routing paths for network communication. Data is transferred in the form of packets via logical network paths in an ordered format controlled by the network layer.
