Different manual computing devices

A manual computing device as claimed in claim 2 wherein each of said tokens in said first group has a color different from the color of the other tokens in said first group, said colors being yellow, red, white, blue, brown and black, and wherein said tokens are arranged Cited by: 6. Input Devices - these get data into the computer; Processor - this does something with the data to make it useful information; Output Devices-these show the results of processing; Storage Devices - holds the data in the system. #.  · Definition: “ A manual system is like a bookkeeping system in which records maintanance is done by hand, without using a computer system or any automatic system. In this type of system transactions are written in journals, from which the information is manually retrieved into a .

History of Computing: Definition of a Computer - before , a computer was a person who performed arithmetic www.doorway.run 19the definition referred to a machine, rather than a person. The modern machine definition is based on von Neumann's concepts: a device that accepts input, processes data, stores data, and produces output. A computer's CPU accesses RAM, which acts like a middleman between the CPU and non-volatile storage devices. Otherwise, a computer would operate too slow for comfort by relying on non-volatile storage alone. Any data stored in RAM is available to the CPU in quick fashion, acting like the working memory for the CPU.

It's difficult to say because everything that belongs in the computing devices class could be classified as a "computer" as well, because it computes by definition of being a computing device. Hollerith's Tabulating Machine () Considered as the earliest device for calculation, the abacus is used by the Europeans, Chinese, and Japanese for simple addition, subtraction, multiplication, and division. It is made up of wooden frame divided into two parts by a beam. On its upper part is a deck of two rows of beads. Early Beginnings: Manual Computing Devices The first known device for numerical calculating is the abacus. It's invention in Asia Minor dates to approximately to B.C.E.. Abacus users compute bymoving a system of sliding beads arranged in columns on a rack.
