USB-C vs Thunderbolt: A Clear Guide to Ports

Introduction: Why Understanding These Ports Matters

In today’s tech-driven world, USB-C and Thunderbolt ports are everywhere—on laptops, smartphones, monitors, and chargers. While they look identical, their capabilities vary wildly. Choosing the wrong port can lead to sluggish data transfers, inefficient charging, or even device incompatibility!

🔑 Key Insight: USB-C is a physical port shape, while Thunderbolt is a high-speed data protocol (both use the same port).
