What is Computer Science

Look around you. Every phone, laptop, video game and smartwatch is running software designed and built by people. But building software is only one part of a much larger field: computer science — the study of information, and of how it is represented, processed and transmitted by machines.

Whenever you stream a video, search the web or send a message, a chain of computer science ideas is working behind the scenes: the network that delivers your data, the algorithm that ranks your results, the storage that keeps your files.
