Certified Healthcare Technology Specialist (CHTS) Process Workflow & Information Management Redesign Practice Exam

Which order correctly represents the layers of the OSI model from top to bottom?

1. Physical, Data Link, Network, Transport, Session, Presentation, Application

2. Application, Presentation, Session, Transport, Network, Data Link, Physical

3. Application, Physical, Network, Presentation, Data Link, Transport, Session

4. Data Link, Transport, Physical, Session, Network, Application, Presentation

The correct answer is: Application, Presentation, Session, Transport, Network, Data Link, Physical

The order that represents the layers of the OSI model from top to bottom is correctly given in the selection that lists Application as the topmost layer, followed by Presentation, Session, Transport, Network, Data Link, and finally Physical at the bottom. This sequence reflects the actual architecture of the OSI model, a conceptual framework used to understand network interactions in seven distinct layers. Each layer serves a specific purpose: - The Application layer provides network services directly to the user's applications. - The Presentation layer handles data translation, encryption, and compression. - The Session layer establishes, manages, and terminates sessions between applications. - The Transport layer is responsible for end-to-end communication and data transport. - The Network layer manages the routing of data packets. - The Data Link layer is concerned with node-to-node data transfer and error correction. - The Physical layer deals with the physical connection between devices and the transmission of raw data bits. This structured approach is crucial for networking professionals to properly design and troubleshoot network systems, as it highlights how different layers interact and depend on one another. Understanding the correct order is fundamental for grasping how data moves through a network, making the correct answer essential for mastering the concepts taught in the course.
