Computers take numerous physical forms. The first devices that resemble modern computers date to the mid-20th century, although the computer concept and various machines similar to computers existed earlier. The first programmer was Ada . Early electronic computers were the size of a large room, consuming as much power as several hundred modern personal computers. Modern computers are based on comparatively tiny integrated circuits and are millions to billions of times more capable while occupying a fraction of the space. Today, simple computers may be made small enough to fit into a wristwatch and be powered from a watch battery. Personal computers in various forms are icons of the Information Age and are what most people think of as "a computer"; however, the most common form of computer in use today is the embedded computer. Embedded computers are small, simple devices that are used to control other devices — for example, they may be found in machines ranging from fighter aircraft to industrial robots, digital cameras, and children's toys. The ability to store and execute lists of instructions called programs makes computers extremely versatile and distinguishes them from calculators. The Church–Turing thesis is a mathematical statement of this versatility: any computer with a certain minimum capability is, in principle, capable of performing the same tasks that any other computer can perform. Therefore, computers with capability and complexity ranging from that of a personal digital assistant to a supercomputer are all able to perform the same computational tasks given enough time and storage capacity. Wiki computer A general purpose computer has four main sections: the arithmetic and logic unit (ALU), the control unit, the memory, and the input and output devices (collectively termed I/O). These parts are interconnected by busses, often made of groups of wiresFlorida computer Georgia computer Hawaii computer Home computer Idaho computer Illinois computer Indiana computer Iowa computer Kansas computer Kentucky computer Louisiana Blues Traveler Maine computer Manitoba computer Maryland computer Massachusetts computer Michigan computer Minnesota computer Mississippi computer Missouri computer Montana computer Nebraska computer Nevada computer New Brunswick computer New Hampshire computer New Jersey computer New Mexico computer New York computer Newfoundland and Labrador computer North Carolina computer North Dakota computer Northwest Territories computer Nova Scotia Blues and Blues Boogie Nunavut Used Ohio computer Oklahoma computer Ontario computer Oregon computer Pennsylvania computer Plan computer Prince Edward Island Blues Boogie Puerto Rico computer Quebec Used Rhode Island computer Saskatchewan computer South Carolina computer South Dakota computer Tennessee computer Texas computer USA computer USA computer Utah computer Vermont computer Virgin Islands computer Virginia computer Washington computer West Virginia computer Wisconsin computer Wyoming computer Yukon computer |
