Computer Memory Basics Although memory is technically any form of electronic storage‚ it is used most often to identify fast‚ temporary forms of storage. If your computer’s CPU had to constantly access the hard drive to retrieve every piece of data it needs‚ it would operate very slowly. When the information is kept in memory‚ the CPU can access it much more quickly. Most forms of memory are intended to store data temporarily. As you can see in the diagram above‚ the CPU accesses memory according

Running head: Computers COMPUTERS BY Eunice 10/20/13 Introduction An English writer named Richard Braithwaite first recorded the word “computer” in his book entitled “The young man’s gleanings”. Computers are now the most common electronic device among individuals and businesses in the world. Computers serve as a means of solving sophisticated problems easily and quickly. Now the forensic science department also use computers in their investigations. And banks also stopped counting money

Ever since the development of the ENIGMA (the first digital computer)‚ computers have inspired our imagination. In this period came the World War II code breaking machine designed by Alan Turing‚ and Von Neuman’s ENIAC which can be called dinosaurs compared to present day PCs. In the earlier days‚ computers were so huge that it took an entire building‚ or at least a floor to occupy one. Computers of that era were very slow by today’s standards. In the non-ending struggle to increase

andentanglement‚ to perform operations on data.[1] Quantum computers are different from digital computers based on transistors. Whereas digital computers require data to be encoded into binary digits (bits)‚ each of which is always in one of two definite states (0 or 1)‚ quantum computation uses qubits (quantum bits)‚ which can be in superpositionsof states. A theoretical model is the quantum Turing machine‚ also known as the universal quantum computer. Quantum computers share theoretical similarities

Computers in Education The typical school has 1 computer per 20 students‚ a ratio that computer educators feel is still not high enough to affect classroom learning as much as books and classroom conversation. Some critics see computer education as merely the latest in a series of unsuccessful attempts to revolutionise education through the use of audio- and visually-oriented non print media. For example‚ motion pictures‚ broadcast television‚ filmstrips‚ audio recorders‚ and videotapes were all
