Microcontrollers are often low-power devices. A desktop computer is almost always plugged into a wall socket and might consume 50 watts of electricity. A battery-operated microcontroller might consume 50 milliwatts.
 A microcontroller has a dedicated input device and often (but not always) has a small LED or LCD display for output. For example, the microcontroller inside a TV takes input from the remoter control and displays output on the TV screen. The controller controls the channel selector, the speaker system and certain adjustments on the picture tube electronics such as tint and brightness.
 A microcontroller is often small and low cost. The components are chosen to minimize size and to be as inexpensive as possible.

Answer 1

Microcontrollers are often low-power devices. A desktop computer is almost always plugged into a wall socket and might consume 50 watts of electricity. A battery-operated microcontroller might consume 50 milliwatts.
微控制器通常是低能量装置。台式电脑几乎总是插进墙上的插座，需消耗50瓦特的点。一个有电池操作的微控制器也会消耗50毫瓦。

微控制器通常有精细的输入设备，通常（但不总是）都会有一个小的发光二级管
或一个液晶显示器作为输出设备。例如，在电视里的微控制器从遥控器里输入，从电视屏幕现实输出。遥控器控制频道选择器，扬声器系统及对如色彩和亮度等显像管电子的一些调整。

一个微控制器通常很小，并且成本很低。组件的大小是越小越好，价格越低越好。
