UNIT-I INTRODUCTION INTRODUCTION TO COMPUTER The term “Computer” is derived from the Latin word “Computare” which means “to compute” or “to calculate”‚ so it is considered to be calculating device. In fact‚ the main objective of inventing the computer was to create a fast calculating machine. But now-a-days more than 75% of non-mathematical or non-numerical work is carried out by the computers. Today‚ computer technology has spread to every sphere of existence of modern man‚ from railway

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

The influence of madness‚ Gilman’s personal life and medical experiences and the oppression of women had all helped motivated Gilman to write this text. The social expectations of a woman’s place in society or the world during the late 19th and early 20th century greatly impacted Gilman and motivated her to address the universal truth that only the mind can set itself free. Firstly‚ the

Computer Science vs. Computer Engineering Moving from High School to college is often a rollercoaster on the mind of most students. After the appliance and acceptance process‚ we then encounter a bigger question: What will our major be? As a computer and technology lover‚ I had a hard time understanding and choosing between computer science and computer engineering; even though I already knew that I wanted to study computers. People often think that studying computer science is the same as studying

CHAPTER ONE COMPUTER SYSTEM FUNDAMENTALS 1.1 Computer System as a Universal Tool A computer system is an electronic device that accepts inputs; transform the input through some processes to obtain output or information that can aid effective decision making. Information originated from raw data which by its own simple definition is any raw fact or figure that can be subjected to a form of manipulation before it can be trusted for decision making. Data can originate from various sources depending
