THE VALUE OF COMPUTER EDUCATION TODAY Necessity is the mother of revolution. The saying holds true for computers also because computers were invented as a result of a main search for a fast and an accurate calculating device. A few days ago there were only few computers in our country. They were enormous and expensive machines. Although abacus was invented around 600 B.C. It is interesting to know that it can calculate at an amazing speed. The first mechanical adding machine was invented by Blaise

Computer Simulation * A software program that runs on any computer that attempts to simulate some phenomenon based on a scientist’s conceptual and mathematical understanding of the given phenomenon. * The scientist’s conceptual understanding is reduced to an algorithmic or mathematical logic‚ which is then programmed in one of many programming languages (Fortran‚ C‚ C++‚ etc.) and compiled to produce a binary code that runs on a computer. * Have become a useful part of modeling

Computer Multimedia Sam Quesinberry Computers have come a long way very fast since there start in the 1940’s. In the beginning they were mainly used for keeping financial records by banks and insurance companies‚ and for mathematical computations by engineers and the U.S. Military. However‚ exciting new applications have developed rapidly in the last few years. Two of these areas is Computer Graphics and sound. Computer graphics is the ability of the computer to display‚ store and transmit

Computer Hardware came about when machines needed separate manual actions to be able to perform specific mathematical functions. Luckily in 1941‚ a man by the name of Konrad Zuse invented what was considered the first working‚ fully operable computer. Prior to this‚ most of the calculations were done manually to calculate by people with adding machines. Today these adding machines are better known as calculators. Back then‚ all you had to do is push buttons‚ but in today’s modern software technology
