Explanation of Solution

Layer 3:

  • In OSI model, network layer is also termed as Layer 3.
  • Network layer is used to deliver the messages from source to vital destination.
  • Network layer protocols transfers the message from source to destination.
    • It delivers the message from end-to-end.
    • It provides a universal addressing scheme for all nodes in the network and every node should use the same addressing scheme.
    • It provides a guarantee in the delivery of message in a point-to-point connection with the help of data link layer.

Explanation for incorrect options:

Layer 4:

  • In OSI model, transport layer is also termed as Layer 4.
  • The purpose of transport layer in OSI model 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 “A” is wrong.

Layer 2:

  • In OSI model, data link layer is also termed as Layer 2.
  • It makes the transmission of data reliable 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 send the acknowledgement to the source.

Hence, the option “C” is wrong.

Layer 1:

  • In OSI model, physical layer is also termed as Layer 1.
  • Physical layer is used for structuring the undefined data or information over the medium.
  • It defines about the interfaces related to the physical medium.

Hence, the option “D” is wrong.

Write a class named Patient that has attributes for the following data: First name, middle name, and last name Address, city, state, and ZIP code Phone number Name and phone number of emergency contact The Patient class’s _ _init_ _ method should accept an argument for each attribute. The Patient class should also have accessor and mutator methods for each attribute. Next, write a class named Procedure that represents a medical procedure that has been performed on a patient. The Procedure class should have attributes for the following data: Name of the procedure Date of the procedure Name of the practitioner who performed the procedure Charges for the procedure The Procedure class’s _ _init_ _ method should accept an argument for each attribute. The Procedure class should also have accessor and mutator methods for each attribute. Next, write a program that creates an instance of the Patient class, initialized with sample data. Then, create three instances of the Procedure class,…
