A modern PC is both simple and complicated. It is simple in the sense that over the years, many of the components used to construct a system have become integrated with other components into fewer and fewer actual parts. It is complicated in the sense that each part in a modern system performs many more functions than did the same types of parts in older systems.
This section briefly examines all the components and peripherals in a modern PC system. Each item is discussed further in later chapters.
Here are the components and peripherals necessary to assemble a basic modern PC system:
