A single board computer is a total computer that stands on a single circuit board. It is a circuit board that contains all the components to make a complete computer, such as the processor, memory (RAM), I/O, processor clock and audio and video interfaces. Single board computers may be used as stand-alone units, embedded units or backplane units.Today, single board computers have found wide use in industrial processes. These small-form factor computers are often used in industrial machines in a rack-mount format that performs complex processes.
Industrial single board computers are special than your regular home or office desktop

computers. They are even quite different from other single board computers embedded in electronic products. These differences are dictated by their industrial functions. Industrial single board computers are usually designed to perform a solitary task, unlike desktop computers that are for multitasking. Because they are used in industrial processes, industrial single board computers are specifically designed to withstand various industrial factors such as shocks, vibrations, humidity, electromagnetic interference, radio frequency interference, dust, flash and mist.
