The TCP/IP Model is a four-layer communication framework used for internet and network communication.

Elaboration:

It is a simplified version of the OSI Model:

1. Network Interface Layer – Handles physical connections.
2. Internet Layer – Manages IP addressing and routing.
3. Transport Layer – Ensures reliable communication using TCP/UDP.
4. Application Layer – Supports protocols like HTTP, FTP, and DNS.

Example:

When you send an email, SMTP (Application), TCP (Transport), and IP (Internet) protocols work together to ensure delivery.
