Describe models of the following processes:

Lighting a wood fire.

Cooking a three-course meal (menu of your choice)

Online Course Registration System

The correct answer and explanation is :

Models of Three Processes

1. Lighting a Wood Fire (Process Model: Sequential Model)

Lighting a wood fire follows a sequential process where each step builds upon the previous one.
Steps:

1. Gather Materials – Collect dry wood, kindling, and fire starters (e.g., newspaper).
2. Prepare Fire Base – Arrange kindling in a pyramid or teepee shape.
3. Ignition – Use a match or lighter to ignite the fire starter.
4. Small Flames Development – The fire spreads to kindling.
5. Add Larger Wood – Once the kindling is burning, place larger logs gradually.
6. Sustaining the Fire – Ensure proper airflow and occasionally add wood.
7. Extinguishing the Fire – Pour water or cover with dirt to put out.

This model follows a linear sequence where each stage must occur in order for the process to be successful.

2. Cooking a Three-Course Meal (Process Model: Parallel Model)

A three-course meal consists of an appetizer, main course, and dessert, often prepared in parallel.

Example Menu:

• Appetizer: Tomato Basil Soup
• Main Course: Grilled Salmon with Garlic Mashed Potatoes
• Dessert: Chocolate Lava Cake

Steps (Parallel Process):

1. Prepare Ingredients for All Courses – Chop vegetables, marinate salmon, mix dessert batter.
2. Start Cooking Dessert First – Since the lava cake needs time to bake and cool.
3. Simultaneously Cook Soup and Salmon – While soup simmers, grill salmon and prepare mashed potatoes.
4. Final Touches – Garnish soup, plate the salmon, remove lava cake from oven.
5. Serve in Order – Serve soup first, followed by the main course, then dessert.

This model demonstrates parallel processing, where different tasks happen simultaneously to save time.

3. Online Course Registration System (Process Model: Transactional Model)

An online course registration system follows a transactional model, ensuring that actions like registration and payment are secure and consistent.

Steps:

1. User Authentication – Student logs in using credentials.
2. Course Selection – Student browses available courses and selects preferred ones.
3. Seat Availability Check – System verifies course availability.
4. Enrollment Confirmation – If seats are available, the system locks the student’s spot.
5. Payment Processing – If required, the system processes payments or verifies eligibility.
6. Final Registration Update – The system updates records, and the student receives a confirmation email.
7. Error Handling – If an issue occurs (e.g., payment failure), the system rolls back changes.

This model ensures data integrity and prevents errors, making it a reliable process.

Each process model suits its respective application: sequential for fire lighting, parallel for cooking, and transactional for online registration, ensuring efficiency and correctness.
