  1. Is USB Type C and Thunderbolt 3 the same? No, they are not the same. USB Type-C refers to the physical connector type, which is used by various standards including USB 3.1 and Thunderbolt 3. Thunderbolt 3 uses the USB Type-C connector but offers higher bandwidth (up to 40 Gbps), more features like daisy-chaining, and the ability to carry power and video signal.
  2. Are Thunderbolt 2 and 3 cables the same? No, they are different. Thunderbolt 2 uses a Mini DisplayPort connector, while Thunderbolt 3 uses a USB Type-C connector. They are not directly compatible without an adapter.
  3. Is USB-C 3.2 the same as Thunderbolt 3? No, they are different. USB-C 3.2 refers to the latest version of the USB standard using a USB-C connector, with speeds up to 20 Gbps. Thunderbolt 3, while also using a USB-C connector, offers speeds up to 40 Gbps and additional features like daisy-chaining and support for dual 4K displays.
  4. Is Thunderbolt for Apple only? No, Thunderbolt is not exclusive to Apple. Initially, it was more commonly found on Apple devices, but it is now available on a variety of PCs, laptops, and peripherals from various manufacturers.
  5. Can I use a normal USB-C cable for Thunderbolt 3? While a normal USB-C cable will fit into a Thunderbolt 3 port, it will not support Thunderbolt 3’s full features and speed. It will operate at the speed and functionality of the USB standard of the cable, which is typically lower than Thunderbolt 3.
