📚 Topic Summary
Unplugged activities in computer science involve learning programming concepts without using a computer. These exercises typically use physical objects, role-playing, or simple diagrams to represent code. Understanding output in this context means predicting the result or behavior of a program given a certain input, all done manually. These activities build computational thinking skills and make abstract concepts more tangible.
