computer is a machine that manipulates data according to a list of instructions.The first devices that resemble modern computers date to the mid-20th century (1940–1945), although the computer concept and various machines similar to computers existed earlier. Early electronic computers were the size of a large room, consuming as much power as several hundred modern personal computers(PC).[1] Modern computers are based on tiny integrated circuits and are millions to billions of times more capable while occupying a fraction of the space.[2] 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.

个人理解译文：

电脑是一种可以根据指令操作数据的机器。第一台设备，类似于现代计算机可以追溯到20世纪中，尽管计算机概念和各种机器类似于电脑存在。早期的电子计算机是一个大房间的大小，使用尽可能多的权利数百万到数十亿倍更有能力，同时占用空间的一小部分。今天，简单的电脑可以足够小，适合一个手表，从手表电池供电。个人电脑，以多种形式，是信息时代的标志，是大多数人认为的“计算机”；然而，最常见的电脑在使用中今天是嵌入式计算机。嵌入式电脑很小，简单的设备，用于控制其他设备，例如，他们可能会发现在机器从战斗到工业机器人，数码相机，儿童玩具。
