🌐 Understanding the TCP/IP Model

The TCP/IP model is a foundational framework for networking, divided into four layers that define how data is transmitted across networks. Here's a breakdown:

  1. Application Layer

    • Handles high-level protocols like HTTP, FTP, and SMTP.
    • 📌 Example: When you browse the web, this layer manages your request and response.
    • Application Layer

  2. Transport Layer

    • Ensures data is transferred reliably between devices.
    • 🔗 Key protocols: TCP (for reliable delivery) and UDP (for faster, less reliable transmission).
    • Transport Layer

  3. Internet Layer

    • Responsible for routing data across networks using IP addresses.
    • 🧭 Core protocol: IP (Internet Protocol) to manage addressing and routing.
    • Internet Layer

  4. Network Access Layer

    • Deals with physical transmission of data (e.g., Ethernet, Wi-Fi).
    • ⚙️ Functions: Data encapsulation and hardware communication.
    • Network Access Layer
