The "system" word fit and is vague enough to cover all cases, and so to describe a system compliant to Open System Interconnection, the use "Open system" which is shorter and more practical that "OSI compliant system" only a guess tough, I don't think you'll get an authoritative answer from anyone else than the authors.
Improve this answer. Thanks for the reply. The transport layer manages the delivery and error checking of data packets. It regulates the size, sequencing, and ultimately the transfer of data between systems and hosts.
The session layer controls the conversations between different computers. A session or connection between machines is set up, managed, and termined at layer 5. Session layer services also include authentication and reconnections.
The presentation layer formats or translates data for the application layer based on the syntax or semantics that the application accepts. Because of this, it at times also called the syntax layer. This layer can also handle the encryption and decryption required by the application layer. At this layer, both the end user and the application layer interact directly with the software application.
This layer sees network services provided to end-user applications such as a web browser or Office The application layer identifies communication partners, resource availability, and synchronizes communication.

Data Link Layer The data link layer establishes and terminates a connection between two physically-connected nodes on a network. Physical Layer The physical layer is responsible for the physical cable or wireless connection between network nodes.
Understand and communicate the process followed by components communicating across a network. Perform troubleshooting, by identifying which network layer is causing an issue and focusing efforts on that layer. The OSI model helps network device manufacturers and networking software vendors: Create devices and software that can communicate with products from any other vendor, allowing open interoperability Define which parts of the network their products should work with.
Communicate to users at which network layers their product operates — for example, only at the application layer, or across the stack. See how Imperva Web Application Firewall can help you with application security. Request demo Learn more. Article's content.
