🧠 Understanding the OSI Model 🌐
Every data transfer you make , from sending an email to streaming a video, passes through 7 layers of the OSI Model.

From the Physical Layer that connects your cables ⚙️
to the Application Layer where users interact 💬,
each level plays a vital role in how networks communicate and stay secure.

💡 Mastering the OSI Model is key to understanding networking and cybersecurity fundamentals.

🌐 NETWORKING FUNDAMENTALS 💻
Every cybersecurity professional needs to start here, understanding how data moves, switches, and stays protected.

📶 From Routing Protocols like RIP & OSPF
🔀 To Switching Protocols like VLAN & STP
🧱 And Firewall Protocols like NAT & IDS —
these are the building blocks of a secure network! 🔒

💡 Mastering these will set you apart in your cybersecurity journey.
