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 computing

superposition 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 Society Today computers are a part of everyday life‚ they are in their simplest form a digital watch or more complexly computers manage power grids‚ telephone networks‚ and the money of the world. Computers are a relatively new invention. The first computers were built fifty years ago and it is only in the last thirty or so years that their influence has affected our everyday life. Personal computers were introduced as recently as the early eighties. In this short time they

These individuals are typically completely comfortable with the computer technology that surrounds them in their daily lives. One of the most ancient forms of communication known as hand writing is being replaced by typing. Even with the invention of the typewriter‚ it was still not uncommon to handwrite memos‚ letters

The Computer Age Believe it or not‚ but the age of computers is upon us. I believe Computers are not only here to stay‚ but in my opinion computers are the wave of the future. Only a device like the computer can change the way we work‚ live‚ and think. I see computers taking us places where no man has gone before. Twenty years ago people were just not up to date with computers back then. I mean if you ask someone about a computer‚ they probably would say something like‚ what in the world are

Why Is A Computer So Powerful? (CHARACTERISTICS OF COMPUTERS) 1. Programmability This is the most important feature of any computer. Programmability can be simply defined as the ability of a functional unit to perform certain pre-defined operations or tasks automatically and independently under the control of running program‚ with minimum user intervention or assistance. 2. Speed of operation A computer is a very fast device. It can perform in a few seconds the amount of a work that a human

As we all know‚ computers can be found everywhere these days. They have changed the way we think‚ live and study‚ etc. The fact that computers have made incredible changes to our society‚ makes them very special invention. Although they might be only as important as other inventions such as electricity‚ airplanes‚ etc‚ it is their ability to be programmed to perform an amazing variety of tasks distinguishes computers from all the other inventions. Computers are playing an effective role in different

LIMITATION OF COMPUTER Computer has done this and that. Actually this is not the computer which has done this but the user. Despite its various features‚ a computer does have the following limitations: a.No Self Intelligence Today‚ a computer is able to do a work which is impossible for man. Computers are used to do risky and dangerous work and where sharp actually is needed. But it does not have any intelligence of its own. It works according to the instruction only. b. No Decision-Making power

“Computers are almost everywhere‚ and they affect most walks of life-business‚ education‚ government‚ the military‚ hobbies‚ shopping‚ research‚ and so on. What aspects of your life can you think of that still seem relatively unaffected by computers and technology? Is this a good thing or a bad thing‚ and is it likely to last? What aspects of your life have been made the most conspicuously affected by technology? Has anything been made worse or harder in your life by the advance of computers? What
