Osi model
Understand the Problem
The question is asking about the OSI model, which is a conceptual framework used to understand network communication in seven distinct layers. It can involve definitions, explanations, and examples of each layer.
Answer
OSI model divides network communications into seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
The OSI model is a conceptual framework that divides network communication functions into seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application. It allows diverse communication systems to communicate using standard protocols, promoting interoperability.
Answer for screen readers
The OSI model is a conceptual framework that divides network communication functions into seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application. It allows diverse communication systems to communicate using standard protocols, promoting interoperability.
More Information
The OSI model was created to address interoperability issues in network communication, ensuring uniformity and standardization across different systems and networks. Although it is less used in practice compared to the TCP/IP model, it is still valuable for understanding and teaching network protocols.
Tips
Confusing the layers or their order is common. Remembering the mnemonic 'Please Do Not Touch Steve's Pet Alligator' can help: Physical, Data Link, Network, Transport, Session, Presentation, Application.
