Book review - Essay Example It is noteworthy that advancement in computers has also transformed the communication landscape. Computers are presently being used in information exchange in any form. This has created advancement in information technology globally. This paper appreciates that people comprehend the history of computing differently because some opinions are informed by traces of information available today of what happened in the past while others viewpoints are informed by issues about computers that are of interest today. Therefore, it presents a timeline on the history of computing according to my own understanding. History of Computing: The Timelines The 14th BC – 1800’s – Abacus and the Slide Rule Abacus remains one of the most primitive machines purposefully developed to aid people in computations. The machine has been on use several centuries even after better-designed devices started coming into the market. Around 17th BC a device that worked even in a more interesting wa y to assist in calculations was generated. The Slide Rule worked manually in doing calculations. Its components included a simple ruler and an impermanent piece that had graduations of parallel logarithmic ranges (Turner, 2006). The greater need to make computations even more easy generated more interest among scholars leading to additional innovations. Blaise Pascal another mathematician designed Pascaline. The mechanical calculator, which acted as an adding machine was developed in 1642, further facilitated the creation of Pascal programming language. 1800’s - Difference Engine and Analytical Engine Charles Babbage also developed what was famously called a â€Å"Difference Engine† in 1830’s. However, later it designed another device â€Å"Analytical Engine.† Both of these designs had five important components that have remained key features of modern computers. The Engines had an input device, component that stored numbers to be calculated, a processor that computed numbers, a component that controlled all machines’ tasks, and finally a component to generate processed numbers. Herman Hollerith also developed the first ever device using electricity to compute numbers in 1890’s. 1900 – 1950 – Computing Machines The period between 1900 and 1950 also saw major computing advancements taking place. Howard Aiken in 1932 started working for IBM and developed the Harvard Mark 1 an electromechanical engine that borrowed massively from Babbage’s Analytical Engine. The period around 1939 saw Atanasoff Berry and Clifford Berry of Iowa State University expanded the computing world by creating the first device that worked electronically. The machine used a binary system in calculations and used different components for processing numbers and storage. Further, in 1943, in order to emerge superior during the British war, many vacuum tube computers emerged and were used to disable the German codes; thus, led to en d of the war faster (Black, 2001).   The machines were named Colossus Mark 2. In 1946, John Mauchly and Presper Eckert both expanded the ideas behind Colossus in order to come up with Electronic Numerical Integrator and Computer, ENIAC that emerged as the world’s all-purpose computer (Black, 2001). John Von Neumann further developed ENIAC to create an Electronic Discrete Variable Automatic Computer, EDVAC that generated computers that are more superior. 1950 – 1970 – Punch Card Technology The computing world welcomed the first computers to be commercially supplied to the markets.
