Achievements of science Essay

The history of human civilization is a introduce of the achievements of science, amongst other things. We have been observing great scientific achievements since the dawn of the twentieth century. But the invention which has brought about a revolutionary change in the world is data processor. The history of computer science began long before the in advance(p) discipline of computer science that emerged in the 20th century, and hinted at in the centuries prior. The progression, from mechanical inventions and mathematical theories towards the modern concepts and machines, formed a major donnish field and the basis of a massive worldwide industry. The man tooshie the thought of this great invention was a British professor of maths named Charles Babez. In 1830, he designed a machine named Analytical engine which had common sides with the turn in structure of computer. Then step by step, computer got its current shape through various procedure and research.In footing of operativ e criteria, there be ternion kinds of computers. These are latitude, digital and hybrid. The analog computer industrial plant by chronological systemally counting of shifting figures and the digital computer works by using mathematical methods and counting galvanic waves. The hybrid computer is a combination of the above two it works by using both characteristics of analog and the digital. According to the size, space and working capacity, there are four variations of digital computer super computer, central processing unit computer, mini-frame computer and micro computer. The total figure of computer is divided into three main units commentary unit, central processing unit (CPU), rig unit. The input unit receives the data and delivers to memory, memory stores it for the time being 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 procedure is executed by the control unit. The arithmetic logic unit, control unit and memory ca commit the CPU. The fields of application of computer are uncountable. From space research to own(prenominal) amusement, each and every fact of human race 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 trying to invent celluloid intelligence and if thatll possible, computer will be substitute of human. There is no argument that computer has done incalculable benefits to man. But as its amachine, it can also be operated against mankind. So, it depends on us to use it in a proper way and get the best output from it and have a life of comfort, easy and peace.
