Top Data Structure Quizzes & Trivia

How does your computer access data stored in an array? Does your filing cabinet store your personal information in a hierarchical database, or a relational one? Could you explain what a hash table is to a friend without leaving him scratching his head by the time you were through?

Data structures describe the ways that a computer can pack away information for storage, from the details your doctor has entered into your health record, to the essay you saved on your hard drive; from the saved games on your video game console, to the music on your MP3 player. Want to know more about the magic that these machines work every time you click “Save As”? Take our data structure quiz to find out more!
