System Components
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.
The components and peripherals necessary to assemble a basic modern PC system are lis-
ted in Table 2.3 .
