Many electronic devices can make the business run more smoothly. These include cash registers as well as security systems, landlines and the internet. Although these may seem obvious, there are other less obvious electronic devices entrepreneurs should own. These include laser coding depaneling, conformal coating equipment.
These types of electronic machines are used in a variety of manufacturing and production processes, specifically the warehousing of micron-sized components such as IC chips and resistors. Stock management errors could be made if the items are not clearly marked and inspected visually. By installing handheld computers that connect product information to shelf information, a mistake-free inspection process can be realized, and the speed of inspection and shipping increased.
Commercial electronics include power generators that convert DC electricity to other forms of energy such as AC or diesel. These electronic devices are used both for industrial and domestic reasons.
Although none of these was a computer in its own right however the practical knowledge gained from the invention of business machines in the 19th century was instrumental in helping to create the foundations for modern computing. It was not until the mid-20th century that Alan Turing and others produced an entirely functional machine capable of performing the logical functions. The machine, known as the Colossus was built at Bletchley Park with great secrecy to decipher the codes and ciphers created by German electromechanical devices such as the Enigma and Geheimschreiber.
