Technology is everywhere. But do you really know how it works? Where it came from?

Pew Research Center quizzed 1,066 Americans recently, and found we still have plenty to learn: Vocabulary, tech milestones, the meanings of privacy policies. Yikes.

Let's just say admitting what we don't know is the first step toward better understanding.

"Policymakers, tech designers, and those orienting their organizations around digital life can profit from knowing just how 'technology literate' people are and where gaps in their knowledge might be," said Aaron Smith, senior researcher at the Pew Research Center. "Just because people use these gadgets a lot doesn't necessarily mean they know everything about how they work and where they came from."
