HISTORY AND APPLICATIONS OF COMPUTERS || INTRODUCTION When more than one thing is needed to work together before an action can take place‚ we say we have a system. The computer needs several things before it can be used to solve problems. Therefore‚ we say the computer is a system. We may have systems around us even in our body. How we eat or what happens to the food we eat is a system. This is called the Digestive System. We need mouth‚ tongue‚ teeth and stomach for us to make good

Computers have made a triumphal entry into education in the past decade‚ and only a dyed-in-the wool Luddite would deny that they have brought significant benefits to teachers and students alike. However‚ an uncritical use of computers can be just as disadvantageous to students as a refusal to have anything to do with them. In this article I discuss some of the ways that computers can be used in English language teaching‚ with a view to helping colleagues make the most of the opportunities they offer

Computer architecture or digital computer organization is the conceptual design and fundamental operational structure of a computer system. It’s a blueprint and functional description of requirements and design implementations for the various parts of a computer‚ focusing largely on the way by which the central processing unit (CPU) performs internally and accesses addresses in memory. It may also be defined as the science and art of selecting and interconnecting hardware components to create computers

What are the Parts of Computer? The Parts of a Desktop Computer are: 1. System unit The system unit is the core of a computer system. Usually it’s a rectangular box placed on or underneath your desk. Inside this box are many electronic components that process information. The most important of these components is the central processing unit (CPU)‚ or microprocessor‚ which acts as the "brain" of your computer. Another component is random access memory (RAM)‚ which temporarily stores

Chapter 1 1. Explain the difference between engineers and technologists. Engineers are problem solvers. They are creative to use technical means to solve problems. They design products‚ systems‚ devices‚ and structures to improve our living conditions. They work with engineers and are concerned with the practical aspects of engineering in planning and production. 2. How can visualizing help an engineer in the design process? Visualization can help an engineer to mentally picture things
