EST. TIME: 45 minOSI vs TCP/IP Reference Models
To study and compare the OSI (Open Systems Interconnection) reference model and the TCP/IP (Transmission Control Protocol/Internet Protocol) model.
Theory
The OSI Model is a conceptual framework that standardizes the functions of a communication system into seven abstraction layers. Developed by ISO in 1984, it provides a universal set of rules for networking.
The TCP/IP Model is a more simplified and practical model used for the modern internet. It consists of four layers that map to the OSI model's seven layers.
Key Differences:
- OSI is a generic, independent model; TCP/IP is based on standard protocols.
- OSI has 7 layers; TCP/IP has 4 layers.
- OSI provides a clear distinction between services, interfaces, and protocols.
Procedure
- Select the OSI vs TCP/IP simulation from the dashboard.
- Click on each layer of the OSI model to understand its functions and protocols.
- Observe the mapping between OSI layers and TCP/IP layers.
- Trigger the "Packet Flow" animation to see how data moves from the Application layer to the Physical layer.
- Review the comparison table and complete the quiz to verify your understanding.
