INTRODUCTION Computer is defined as a combination of electro-mechanical devices (Hardware) capable of accepting data or information‚ processing‚ storing‚ and providing output under the control of some instructions and commands called programs (Software). Computers are machines that perform tasks or calculation according to a set of instruction or programs. Introduce in 1940s the first fully electronic computers were huge machines that required teams of people to operate. Compared to those early

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 with non-deterministic

With increasing popularity of computer games‚ and multimedia home PC users often need an unexpensive computer system upgrade. By building a custom computer one is able to combine componenets‚ and operating system to provide maximal gaming performance. Computers are often called number manipulators‚ because of their ability to run millions of mathematical operations per second (White 43). Computers use binary system of numbers‚ which allows them to operate system of microscopic switches called transistors

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

Computers – An Introduction A computer is defined as an electronic device that accepts input‚ processes it as per the given instructions and produces meaningful output. The term computer is used to describe a device which is combination of electronic and electromechanical devices. It is derived from the word “Compute” which means Calculation. “Charles Babbage” is known as the father of the computer. Data and Information Data refers to raw facts that are gathered and fed to the computer. A computer
