Thin clients are network computers that are especially small so that most data processing occurs on the server. Thin clients are powered by centralized servers and do not contain CD-ROM drives, disc drives, and expansion slots.
Ruggedized computers are similar to personal computers (PC), but they are intended for use on a factory floor or in other harsh environments.
