What is the purpose of the Open Systems Interconnection (OSI) model?

The purpose of the Open Systems Interconnection (OSI) model is to standardize functions of networking systems across multiple layers. This model provides a framework that helps in understanding and designing a network architecture by dividing the communication process into seven distinct layers: Application, Presentation, Session, Transport, Network, Data Link, and Physical.

Each layer has a specific role and communicates with the layers directly above and below it. This modular approach allows for interoperability among various networking products and systems, facilitating better design, implementation, and troubleshooting of network communication. By defining these layers and their associated functionalities, the OSI model enables different systems to communicate effectively, regardless of their underlying technologies.

In contrast, creating a wireless communication protocol, establishing a connection between devices using Bluetooth, and defining wireless signal frequencies are more specialized tasks that do not encapsulate the broader goal of the OSI model, which focuses on providing a structured approach to networking across different technologies and protocols.
