Computing has had a drastic impact on the advancement of science, engineering, economics, and numerous other areas of human endeavor. Nowadays, almost everyone needs to use computers. Computer science will continue to showcase career opportunities, and those who study computer science will have a vital role in shaping the future (Shackelford). Information technology, of course, cannot exist without the use of computers. Before 1935, a computer was a man who performed arithmetic estimates. Somewhere between 1935 and 1945 the definition referred to a machine, rather than a man. The definition of an advanced machine depends on von Neumann's concept: it accepts input, processes data, stores information and produces output (George Mason University). Say no to plagiarism.

Get an Original Essay Before the true power of computing could be realized, the naive perspective of computation had to be overcome. The people who worked to put the computer into practice had to learn that what they were making was not simply a calculator, but a machine that would solve numerous problems, even problems not yet foreseen when the computer was made. Likewise, they had to figure out how to tell such a critical-thinking computer how to interpret different problems. In other words, they had to invent programming. They had to deal with all the huge issues involved in creating such a device, implementing the plan, actually manufacturing the object. The history of addressing these problems is the history of computing (Freiberger). There have been numerous milestones in computing and it has evolved in many ways over the years. The first form of computer dates back to the 14th century and was known as “Abacus”. It is a tool used for calculations by sliding meters along rods or grooves (remember: this is just an example.

He represented values ​​discreetly. Each bead was in a predefined position or the other unambiguously represented a number each (Freiberger). In the 17th century, calculating devices took a new turn thanks to John Napier, a Scottish mathematician who created the “slide rule”. A manual gadget used for estimating which comprises in its simple form a ruler and a movable center table graduated with comparable logarithmic scales.
