The OSI Model Explained

The Open Systems Interconnection (OSI) model is a conceptual framework used to describe the functions of a networking system. Explore each layer to understand its role in network communication.

Layer 7: Application

Provides network services to end-user applications.

Layer 6: Presentation

Translates, encrypts, and compresses data.

Layer 5: Session

Establishes, manages, and terminates sessions.

Layer 4: Transport

Ensures complete data transfer and quality of service.

Layer 3: Network

Manages addressing, routing, and traffic control.

Layer 2: Data Link

Handles error-free transfer of data frames.

Layer 1: Physical

Deals with the physical connection between devices.
