size[edit] Microcomputers (personal computers)[edit] Microcomputers are the most common type of computers used by people today‚ whether in a workplace‚ at school or on the desk at home. The term “microcomputer” was introduced with the advent of single chip microprocessors. The term "microcomputer" itself is now practically an anachronism. These computers include: * Desktop computers – A case and a display‚ put under and on a desk. * In-car computers (“carputers”) – Built into a car‚ for

of the military and industry in the development of electronics‚ computers‚ and information theory. After the 1940s‚ the military remained the major source of research and development funding for the expansion of automation to replace manpower with machine power. Since the 1950s‚ four generations of computers have evolved. Each generation reflected a change to hardware of decreased size but increased capabilities to control computer operations. The first generation used vacuum tubes‚ the second used

Many would think that computer programming is a recent invention but the idea behind writing instructions for a machine to follow then has been around for over a century. Starting from Charles Babbage’s steam driven machine named the Analytical Engine back in 1834. Unlike the simple calculating machines of that time that could perform only a single function‚ Charles Babbage’s Analytical Engine could perform a variety of tasks. This idea caught the attention of Ada Lovelace‚ a mathematician and daughter

COMPUTER CONCEPTS A computer is a machine that processes data and performs tasks according to a set of instructions. To do anything‚ computer must be give specific directions to follow. They get these directions from software. Software‚ such as that used for word processing‚ is a set of step-by-step instruction for the computer‚ written by computer programmers in a programming language like BASIC‚ Pascal‚ or C. Computers also get instructions from you‚ the user. When you use the mouse (more

"Computer forensics is the specialized practice of investigating computer media for the purpose of discovering and analyzing available‚ deleted‚ or "hidden" information that may serve as useful evidence in a legal matter. " (Steen‚ Hassell 2004) Computer forensics has become a very important factor of criminal investigations. Since computers have become mainstream the need for a science that will deal with the technology has become an issue for the judicial and legal system. Some of the areas computer

Super Computer The fastest type of computer. Supercomputers are very expensive and are employed for specialized applications that require immense amounts of mathematical calculations. For example‚ weather forecasting requires a supercomputer. Other uses of supercomputers include animated graphics‚ fluid dynamic calculations‚ nuclear energy research‚ and petroleum exploration. The chief difference between a supercomputer and a mainframe is that a supercomputer channels all its power into executing a

Chapter 1. Introduction to Computer Organization and Computer Evolution I. Computer Organization and Computer Architecture In describing computers‚ a distinction is often made between computer architecture and computer organization. Although it is difficult to give precise definitions for these terms‚ a consensus exists about the general areas covered by each. Computer Architecture refers to those attributes of a system visible to a programmer or‚ put another way‚ those attributes that have a
