Achievements of science Essay

The history of human culture is a record of the achievements of science, amongst other things. We have been observing great scientific achievements since the dawn of the twentieth century. unless the invention which has brought about a subversive change in the world is electronic ready reckoner. The history of computer science began massive before the modern discipline of computer science that emerged in the 20th century, and hinted at in the centuries prior. The progression, from mechanical inventions and numerical theories towards the modern concepts and elevator cars, formed a major academic field and the basis of a massive oecumenic industry. The man behind the thought of this great invention was a British professor of mathematics named Charles Babez. In 1830, he designed a machine named Analytical Engine which had common sides with the present structure of computer. Then gradation by step, computer got its current shape through conglomerate mathematical function and r esearch.In terms of working criteria, there are three kinds of computers. These are analog, digital and hybrid. The analog computer works by chronologically run of shifting figures and the digital computer works by using mathematical methods and counting electric waves. The hybrid computer is a combination of the supra two it works by using both characteristics of analog and the digital. jibe to the size, office and working capacity, there are four variations of digital computer super computer, mainframe computer, mini-frame computer and micro computer. The total figure of computer is divided into three main building blocks input building block, central processing unit (CPU), outturn unit. The input unit receives the data and delivers to memory, memory stores it for the time world and the arithmetic logic unit defines it and directs to process it with necessary programs and delivers the result to output unit to present and memory stores the result permanently if needed.The w hole number is executed by the control unit. The arithmetic logic unit, control unit and memory constitute the CPU. The fields of application of computer are uncountable. From space research to personal amusement, each and every fact of human public life is being influenced by this machine. Governmental issues, commercial vocations, scientific analysis, educational tasks and various works are being operated and controlled automatically by its graft. Now, scientists are nerve-wracking to invent artificial intelligence and if thatll possible, computer will be fill in of human. There is no argument that computer has done incalculable benefits to man. But as its a machine, it can also be operated against mankind. So, it depends on us to use it in a proper way and croak the best output from it and have a life of comfort, easy and peace.
