📚 What is the OSI Model?
The OSI (Open Systems Interconnection) Model is a conceptual framework that defines the different layers involved in networking and communication systems. Each layer plays a crucial role in ensuring smooth data transmission and interaction between devices.
🌟 Key Points Covered:
Physical Layer: The foundation of data transmission, dealing with physical connections and electrical signals.
Data Link Layer: Focuses on node-to-node communication, error detection, and data framing.
Network Layer: Enables routing and logical addressing, ensuring data reaches its destination across different networks.
Transport Layer: Manages end-to-end communication, flow control, and error checking.
Session Layer: Establishes, maintains, and ends connections between applications.
Presentation Layer: Deals with data translation, encryption, and compression to ensure seamless information exchange.
Application Layer: The user interface for network services, allowing software to interact with the network.
