Consider the transportation analogy in Section 6.1.1. If the passenger is analagous to a datagram, what is analogous to the link layer frame?

Link Layer:
- In the OSI (Open Systems Interconnection) model, data link layer is the 2nd layer. This layer is used to transfer data between neighboring network nodes on a Wide Area Network or on the same Local Area Network.
- This layer uses error detection bits and it corrects the errors.
Explanation of Solution
Transportation analogy:
In the section 6.1.1, the travel agent plans a trip for tourists from different places.
- The travel agent decides the convenient plans for the tourists and the agent makes three reservations.
- The three reservation trips are direct between two adjacent locations and also they contain different transportation modes.
- Here, if the passengers are analogous to the datagram, then the transportation modes are analogous to the link layer frame.
Therefore, the transportation modes are analogous to link layer frame.

- 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.
