Output is what comes out of something after work or a process happens inside it. When a factory produces cars, those cars are its output. When you solve ten math problems, those completed problems are your output. The output of a bakery is bread, cookies, and cakes.

The word applies to many situations. A computer's output might be a printed page, an image on screen, or data sent to another program. A writer's output could be three novels in five years. Scientists measure the output of solar panels to see how much electricity they generate. Teachers sometimes talk about student output: the essays, projects, and assignments students produce.

Output always involves transformation. Raw materials or information go in (called input), something happens to them, and something different comes out. A musician's output might be an album: they take their ideas, practice, and recording time (inputs) and create finished songs (output).

The word can describe both quality and quantity. Someone might have high output (they produce a lot) or excellent output (what they produce is really good). A hardworking student with strong output completes assignments carefully and on time. In this sense, output reflects both effort and results.
