 PC (Personal Computer) English PC computer is a computer simulation of electronic components such as objects with computing power, scientific name of the computer. ? originally by John von Neumann invented ? (then equivalent to the current computing power of the computer's calculator, there are three big warehouses, evolved later. Is a way to follow the instructions on the various data and information to automatically processing and handling of electronic equipment 
 In general the computer by two components, namely hardware and software. Hardware includes: monitor, mouse, keyboard, chassis, power supply, motherboard, CPU, sound card, graphics cards, optical drives (floppy drive has been eliminated), memory, hard drives, and some also include card, speakers, headphones, printers, scanners, cameras, handwriting board and other external devices. The software sub-system software and application software. Computer generic computer, electric calculators from the early evolved. February 14, 1946 birth of the world's first electronic digital computer ENIAC (Eni Ak). (The Electronic Numerical Integrator And Calculator) 
 "Eni Ake" computer program originally designed, is a 36-year-old American engineer Glamoc computer help 1943's main task is to analyze shells track. Funding support for the U.S. Ordnance Department of the development work and has established a dedicated research team, from Mo Qili responsible. Chief engineer from the served only 24 years old, Eckert, members Gleneagles is a mathematician, logician Boke Si plus. Computer is called the electronic computer. The world is experiencing the change from the a to b, that is atomic (atom) age to the bits (bit) times change, advances in computer science and technology which will undoubtedly play a pivotal role. After 50 years of quantitative change, applications of computer technology almost everywhere, as people work, live, an indispensable part of learning, and thus the computer has developed a unique culture. 
 In order to define what the computer is the computer classification, the classification of all computing devices is inevitable. The following sections describe several different classification methods. These classifications can be used in conjunction with the description of the accuracy of a particular computer. By use classification is the most obvious classification. Computer manufacturers often use this method to describe their products; users to use the same method to describe the machine to communicate with them. Classification of mechanical manufacturing technology by half Electronics - Semi mechanical optical semiconductor integrated circuit electronic computer transistor quantum computer design features of biological classification of computer according to the modern computer integrated a number of fundamental design features, these features of many contributors to the gradual development in many years out. Design features are often independent of implementation technology. The overall performance of modern computer interaction from the way these features. Classified according to their abilities classification of different computing devices may be the best way according to their inherent capability classification, and not according to their use, implementation technology or design features to classification.
