Speed of a Computer Patrick Reagan Computers and Information Processing/CIS319 David Avery Jr. December 14‚ 2008 Speed of a Computer Computers have evolved dramatically over the last 70 years. The size may be one of the main changes. The first computers were the size of a classroom. Today a computer can fit in an adult hand. Another change is the speed in which the computer operates or processes information. The computer user in today’s market wants information

ensured. A lot of time delaying errors such as mechanical‚ human or Symantec errors will be avoided. Efficiency is also the key in allowing the company to evolve and develop. As the saying‚ being too careful will provide quality service that everyone would want‚ but it would take up a lot of time. By having a monitoring system to follow‚ the company is able to save time and provide maximum assistance and satisfaction to all the employees and clients. In education‚ the computer laboratory is usually monitored

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

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
