Computer Literacy For over fifty years‚ beginning with the famous ENIAC‚ a revolution has been taking place in the United States and the world. The personal computer has changed the way many people think and live. With its amazing versatility‚ it has found its way into every area of life‚ and knowing how to operate it is a requirement for today’s world. Those who have not taken the time to learn about computers often do not even know what to do once one has been turned on‚ and this problem

Few industries have changed so much in such a short time as the computer industry‚ and the pace of change shows no sign of slowing. The computer now has a role in almost every aspect of modern life‚ and it has radically affected the way people work‚ play‚ study and organize their lives. As we enter the 21st century‚ computers are influencing ways of teaching and learning‚ as access to computers in schools is becoming more widespread and varied. Their use enables the learner to develop at his or

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

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

"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

Computer Networks NETWORKING CONCEPTS Network A network is basically an interconnection of various points to make a connected system e.g Road‚ Telephone‚ Social Data Network A computer network therefore refers to an interconnection of computers and other peripherals by use of a communication link Peer to Peer Networks In a peer-to-peer network‚ all computers are considered equal; they all have the same abilities to use the resources available on the network. Peer-to-peer networks are designed

Computer Architecture The circuitry in a computer which controls the manipulation of data is called the central processing unit‚ or CPU. In the machines of the mid-twentieth century‚ CPUs were large units comprised of perhaps several racks of electronic circuitry that reflected the significance of the unit. However‚ technology has shrunk these devices drastically. The CPUs found in today’s desktop computers and notebooks are packaged as small flat squares (approximately two inches by two inches)

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
