Expert Solution & Answer
Chapter 12, Problem 1RQ
Program Description Answer
LANs and WANs supports same protocol at the “Layer 3” of OSI model.
Hence, the correct answer is option “B”.
Expert Solution & Answer
Explanation of Solution
Layer 3: Network layer
- It is the third level of the Open System Interconnection Model (OSI Model).
- Network layer performs the routing of packet from source to destination.
- For routing, it converts the data into packets, and after reaching the destination, it converts back to the data.
- The primary responsibilities of this layer is to set up a logical connection, data forwarding, routing and error reporting.
- Both LANs and WANs use the same protocol of layer 3 and other higher of OSI model.
Explanation for incorrect options:
Layer 2: Data link layer
- It makes the transmission of data reliable, which is provided by the physical layer.
- For reliable transfer, it divides the data into data frames and transmits through the communication channel.
- At the destination, it checks for the transmission error and sends the acknowledgement to the source.
Hence, the option “A” is wrong.
Layer 4: Transport layer
- Its purpose is to provide the reliable transfer of data between two processes in the computer.
- This layer ensures the error-free delivery, no loss of data, and duplication.
Hence, the option “C” is wrong.
Layer 5: Session layer
- Session layer deals with how two devices establish a connection, access, and control the connection in the network.
- It controls the data transfer between two processes in the communicating host.
- It establishes the logical connection between the source and destination.
Hence, the option “D” is wrong.
