How does a computer '''actually work'''? How do they transform what you type into a program that shows cute cat pictures?
A computer is an electronic device for storing and processing data, typically in binary form, according to instructions given to it in a variable program.<ref>https://www.lexico.com/en/definition/computer</ref>
