Computer Science Basics
Build a solid foundation in Computer Science Basics with quizzes covering core concepts like algorithms, data structures, programming fundamentals, and computer systems. These questions help you review key terms and ideas you’ll see in school, interviews, and everyday tech discussions.
Quizzes
Algorithms: sorting, searching, and Big-O
Sharpen your fundamentals in sorting, searching, and Big-O analysis with a mixed-difficulty set built for steady improvement. You’ll compare algorithm trade-offs, reason about time/space complexity, and spot edge cases that break “obvious” solutions. Great for interview prep or refreshing core CS basics.
Programming fundamentals: variables, loops, and functions
Build confidence with core programming building blocks: variables, loops, and functions. This mixed-difficulty quiz checks how well you read code, predict output, and spot logic errors. Choose your preferred question count and difficulty, then answer each multiple-choice question at your own pace—there’s no timer.
Data structures: arrays, lists, and trees
Sharpen your fundamentals of arrays, linked lists, and trees with a mixed-difficulty set built for quick practice. You’ll work through core concepts like indexing, traversal, and complexity, plus common edge cases that trip people up. Pick your preferred question count and difficulty, then learn from each result at your own pace.

Quick context and interesting facts
The term “bug” became popular after a real moth was found in a relay computer in 1947, but the idea of “debugging” existed even earlier in engineering. Many modern CS fundamentals—like binary representation and algorithmic thinking—were formalized decades before personal computers became common.
