The six types of system units are: desktop, media center, notebook, netbook, tablet PC, and handheld. The desktop system unit can be placed horizontally (desktop) or vertically (tower). All input and output devices are located outside the system unit. The media center system unit blurs the line between a desktop computer and a dedicated entertainment center. It combines powerful desktop system hardware with specialized graphics cards. The notebook system unit is portable and much smaller. These system units contain the electronic components, selected secondary storage devices, and input devices. Located outside the system unit, the monitor is attached by hinges. Netbook system units are similar to notebook system units. They are, however, smaller, less powerful, and less expensive. Tablet PC system units are similar to notebook system units, but they support the use of a stylus or pen to input commands and data. Some table PC system units include a monitor that swivels and folds onto its keyboard; others have a keyboard that is completely removable, requiring a stylus for input.
