What exactly is a computer? How does it work? What is it made of? Learn all this and more with Ruby! In Ruby's world anything is possible if you put your mind to it--even fixing her father's broken computer! Join Ruby and her new friend, Mouse, on an imaginative journey through the insides of a computer in search of the missing Cursor. From bits and logic gates to computer hardware, in Journey Inside the Computer, Ruby (and her readers!) will learn the basic elements of the machines that power our world. Then future kid coders can put their knowledge and imaginations to work with fun activities. Praise for Linda Liukas and the Hello Ruby series: "[Linda Liukas] wants kids to understand and embrace basic computer logic, so that they later formulate code in the same effortless and creative way they build structures with LEGO." --The Wall Street Journal "Hello Ruby by Linda Liukas is half picture book and half activity book rolled into one adorable package. What I love about it is that it introduces programming without requiring a computer at all." --GeekMom.com
