Computer science has had a tremendous impact on the advancement of science, engineering, business, and many other areas of human endeavor. Nowadays, almost everyone needs to use computers. Computer science will continue to provide opportunities in testing professions and those who study computer science will play a vital role in shaping the future (Shackelford). Of course, computing cannot exist without the use of computers. Before 1935, a computer was a man who performed arithmetic estimation. Between 1935 and 1945, the definition referred to a machine rather than a man. The advanced definition of machine depends on von Neumann's concept: it accepts inputs, processes data, stores information, and produces output (George Mason University). Say no to plagiarism.

Get the original essay Before the real power of computing could be realized, the naive perspective of computing had to be overcome. The people who worked on making the computer had to learn that what they were making was not just a calculator, but a machine capable of solving many problems, even problems not yet considered when making computers. the computer. Likewise, they had to figure out how to tell such a critical computer how to interpret different problems. In other words, they had to invent programming. They had to take care of all the crucial issues involved in creating such a device, in actualizing the plan, in actually making the thing. The history of solving these problems is the history of computing (Freiberger). Computing has seen a number of milestones and evolved in many ways over the years. The earliest form of the computer dates back to the 14th century and was known as the "abacus." This is an instrument used for calculations by sliding meters along rods or into grooves (Keep in mind: this is just a sample. Get a personalized document now from our expert writers.

Each bead was in a predefined position or the other unambiguously representing 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 includes in its simple form a ruler and a movable centerpiece graduated with comparable logarithmic scales..
