A ruggedized laptop is built to operate reliably in dusty or wet environments and conditions. These computers have a thicker and stronger housing than a regular laptop, and are mainly used for industrial, construction and military purposes. Engineered to be mobile, they are vibration, shock, drop, dust and waterproof, yet are able to comply with other important requirements such as high performance and governmental grade security. They are equipped with both current and legacy I/O ports including serial, ExpressCard, PCMCIA, VGA, and others that are commonly used in outdoor environments. The levels of ruggedization are not standardized, but they are measured by various certifications such as MIL-STD-810,
