Industrial Computers do not differ much when compared with commercially-manufactured PCs. Both of these make use of common computer components such as motherboards and microprocessors, just to name a few. The major difference between these two computer types lies in the way computers for industries are packaged or manufactured. Industrial Computers, for the most part, are packed in such a way that they can still function efficiently even in generally harsh surroundings such as those that exist in many industrial plants. Commercial PCs are often founded on a desktop chassis that is composed mostly of plastic combined with lightweight sheet metals. Commonly, the accompanying keyboard as well as monitor is delivered separately. Given this, commercial computers can be easily damaged when handled carelessly and are thus considered disposable. On the other hand, the computers used in various industries, notably in the manufacturing sector, are often built to last for many years. Typically, they are known to work well under intense heat or cold and even in environments where there are high levels of corrosion.
Additionally, industry-based computers are normally fashioned from rugged aluminium and are usually enclosed in stainless steel. These often have only one panel, with a number of models mounted on walls. The majority, however, are placed on racks especially built for such use, with the monitor coming in as a separate item. Meanwhile, the keypad, along with the LCD display, is usually manufactured as an integral part of the computer system. In terms of applications, several industries are known to settle for those found in many commercially-manufactured PCs, especially when it comes to the non-critical types. This often relates to the costs involved as non-critical applications built into standard desktop computers are usually more affordable. The more critical computer applications, on the other hand, are obviously more expensive mainly because they are designed to withstand extreme environmental pressure. As such, despite the attendant expenses, many manufacturing firms do not have much choice but to utilize these applications. Industrial Computers built with such applications, in return, offer more stable production.
