What are Rugged Computer Systems?    by Art Jones

The most mundane applications of computer systems never call for a tough machine. That's why most of them are designed more with looks in mind than durability. Some applications call for a much tougher outer shell and internal components that won't break under pressure. That is the basic purpose of rugged computer systems.

The design of rugged computers starts from the very base, with the selection of parts and internal components. Many of these components, from chips on the motherboard to hard drives to processors, are selected because of their ability to withstand higher and lower extremes of temperature. In the case of hard drives, they're selected for resistance to shock and damage, as well as data loss.

The case used for a rugged system is durable and resistant to many forms of damage. A device with such a case can typically be dropped down a stairwell, run over by a car, submerged in water and even shot without significant damage. A rugged keyboard is completely sealed against moisture and particles, allowing clean typing in the dirtiest of environments. Screens are selected for their resistance to scratching and damage, as well as the ability to read them in direct sunlight. In addition, these computers are outfitted with top of the line wireless devices to allow them to connect to networks with a very low failure rate.

These sorts of computer systems are designed to meet or exceed the specifications laid out in the military standard MIL-STD-810G. This standard ensures the resultant computer system can withstand high and low pressures, temperatures, and altitudes. It can resist wind, rain, dust and shock. It can withstand humidity, both for resisting rust and corrosion. and for fungus growth. Various forms of constant vibration and sudden impact shocks, as well as particulate exposure or explosive atmosphere are also resisted.

In short, a rugged computers are designed for use in extremely harsh terrain. This makes it ideal for military, maritime and industrial applications where a standard computer would be physically destroyed. As a result, a rugged computer system will last significantly longer and incur lower overall hardware costs in these highly damaging environments. While the hardware is more expensive initially, it does not need to be replaced with anywhere near the frequency of a normal computer in the same situation, and it will not sustain damage and wear and tear that standard computers do.

As long as a computer can pass the various tests set forth in the specific military standard, the device is classified as a rugged system, and is ideal for dangerous and extreme conditions and needs.
