USB 1.0/1.1: Up to 12 Mbps (Low and Full Speed) USB 2.0: Up to 480 Mbps (High Speed) USB 3.0 / 3.1 Gen 1: Up to 5 Gbps (SuperSpeed) USB 3.1 Gen 2: Up to 10 Gbps (SuperSpeed+) USB 3.2: Up to 20 Gbps (with multiple lanes) USB4: Up to 40 Gbps, based on Thunderbolt 3
3. What are the common USB connector types and their uses?	Type A: Standard rectangular port used on computers, TVs, game consoles, and chargers. Type B: Square-ish connector used mainly on printers and some external hard drives. Mini USB: Smaller connector used on older cameras, MP3 players, and some external drives. Micro USB: Smaller than Mini USB, common on older smartphones, tablets, and accessories. USB Type-C: Small, reversible connector found on most modern smartphones, laptops, and peripherals; supports fast data, video, and power delivery.
4. What is USB Type-C and why is it important?	USB Type-C is a small, reversible connector that supports high-speed data, power delivery (up to 100W), and can carry video signals (DisplayPort Alt Mode).
5. Are USB versions backward compatible?	Yes, newer USB versions generally support backward compatibility with older devices and cables, but speeds will be limited to the slowest component.
6. What is USB Power Delivery (PD)?	USB PD is a charging protocol that allows higher power transfer (up to 100W), enabling fast charging of laptops, tablets, and phones.
7. What is the difference between USB 3.0 and USB 3.1?	USB 3.0 (also called USB 3.1 Gen 1) supports speeds up to 5 Gbps, while USB 3.1 Gen 2 doubles that speed to 10 Gbps.
8. Can USB cables carry video?	Yes, USB Type-C cables with DisplayPort Alternate Mode can carry video signals to monitors and TVs.
9. What is Thunderbolt 3 and how does it relate to USB?	Thunderbolt 3 uses the USB-C connector and supports speeds up to 40 Gbps, combining PCIe, DisplayPort, and USB data on one cable.
10. What are the typical USB cable lengths?	USB cables usually range from 0.5m to 3m for passive cables; active repeater cables can extend up to 30m or more.
11. Can I use any USB cable for charging my device?	Generally yes, but to get fast charging speeds (especially USB PD), you need a compatible cable and charger.
12. What is USB OTG?	USB On-The-Go allows devices like smartphones to act as hosts, enabling direct connections to peripherals such as keyboards, mice, or flash drives.
13. What is a USB hub?	A USB hub expands one USB port into multiple ports, allowing you to connect several devices to a single USB port on your computer.
14. How do I identify a high-quality USB cable?	Look for cables certified by USB-IF, sturdy connectors, good shielding, and the appropriate data/power ratings for your devices.
