Question 1

True or false: You can safely plug a USB device into a port upside down—it’s symmetrical.

Accepted Answer

False. USB-A and USB-B connectors are not reversible. Only USB-C is fully reversible, but older types require correct orientation.

Question 2

True or false: USB 3.0 ports are often blue inside to distinguish them from USB 2.0.

Accepted Answer

True. The blue plastic insert is an industry convention for USB 3.0 (SuperSpeed), though not mandatory.

Question 3

True or false: All USB cables are identical inside—only the connectors differ.

Accepted Answer

False. Cables vary in wire gauge, shielding, and data lines. A cheap USB 2.0 cable may fail to carry USB 3.0 signals or high power.

Question 4

True or false: USB stands for Universal Serial Bus, and the original standard was released in 1996.

Accepted Answer

Question 7

True or false: A USB cable can only transfer data in one direction at a time.

Accepted Answer

False. USB uses differential signaling, but modern USB (like USB 3.0) supports full-duplex data transfer—sending and receiving simultaneously.

Question 8

True or false: A USB killer device can physically damage a computer by sending power back into the port.

Accepted Answer

True. USB killers discharge high voltage into the data lines, frying components. They exploit USB’s power delivery capabilities maliciously.
