Beyond the Bits and Bytes
Welcome to NUC7, where we transform complex networking theories into intuitive mastery. In an era dominated by cloud computing and decentralized networks, understanding the OSI Model (Open Systems Interconnection) is no longer a luxury—it's the fundamental language of the digital world.
The 7-Layer Mastery
Layer 1: Physical
The foundation of all communication. From copper cables to fiber optics and radio waves.
Layer 2: Data Link
MAC addresses, frames, and the logic of local network hops.
Layer 3: Network
The art of routing. Understanding IP addresses and global interconnectivity.
Layer 4: Transport
TCP vs UDP. Ensuring your data arrives intact, in order, and reliably.
Layer 5-7: High-Level
Session management, data representation, and application interfaces.
