Title: Compare networking conceptual models.
Course: Cybersecurity in Food and Agriculture, Advanced (18204-II) > Section: Identifying the Necessary Skills to Understand Cybersecurity Concerns

Comparison should include the following models:

- Open systems interconnect (OSI)–a seven-layer model that describes communication between systems; the seven layers include the following:
  - Application
  - Presentation
  - Session
  - Transport
  - Network
  - Data link
  - Physical
- Internet transmission control protocol/Internet protocol (TCP/IP)–a four-layer model that describes communication between systems; the four layers include the following:
  - Application
  - Transport (transport/TCP)
  - Network (Internet/IP)
  - Network Access (link, physical)

Process/Skill Questions:

- What layers of the OSI model are important to the app developer?
- What is the benefit of a layered model for representing network communication systems?
- What does TCP provide which IP does not?
- What is an example of software at the application layer of the TCP/IP model?
