Computer- The Human Innovation

Computer is a mechanism that manipulates records according to a list of instructions. The first devices that resemble modern computers date to the mid-20th century (around 1940 - 1945), although the computer conception and various machines similar to computers existed earlier. Early electronic computers were the dimension of a large room, overwhelming as much power as several hundred modern personal computers. Modern computers are based on tiny integrated circuits and are millions to billions of times more competent while occupying a portion of the space. Today, straightforward computers may be made small enough to fit into a timepiece and be powered from a watch battery. Personal computers, in various forms, are icons of the in sequence Age and are what most people think of as "a computer"; however, the most common form of computer in use today is the entrenched computer. Embedded computers are small, simple devices that are used to organize other devices — for example, they may be found in machines ranging from combatant aircraft to industrial robots, digital cameras, and junior toys.

The ability to store and implement lists of instructions called programs makes computers extremely multitalented and differentiates 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 responsibilities 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 storeroom capacity.

It is difficult to recognize any one device as the earliest computer, partly because the term "computer" has been subject to varying interpretations over time. Originally, the term "computer" referred to a person who performed numerical calculations (a human computer), often with the aid of a mechanical calculating device.
