Modern computers and devices like smartphones and tablets consist of numerous components, even though some devices are really small. First, there are plenty of specialized hardware components like video cards or sound cards, each of which has its own role to play. Then there are the operating system (e.g., Windows) and the programs (e.g., Microsoft Office) that make the device useful to users. Without them, any piece of hardware, no matter how powerful, cannot be used. That's why, in this chapter, we will start by discussing the role each component plays in a modern computer and the basics of how they work together. Then we will focus on the operating system, what it does, how it works, and how to personalize it.
