In this introduction to computer programing, Data Duck leads the exploration through how computers work.  The second half of the book explains how computers do a range of tasks from searching and sorting to pictures and sound.  The text and animated illustrations  work well together to convey each topic.  The explanations throughout the book use analogies kids can understand.  For example, organizing files is compared to cleaning your room and files are compared to books in a library.  As new concepts are introduced, Data Duck provides clarifying details or reminders of previously covered topics.  Questions and activities are on odd numbered pages with answers in the endpapers.  While there is no actual instruction on how to program, this is a solid choice for intermediate age students; providing an age appropriate and informative introduction to the inner workings of computers.
