1, the system composition:
Single-board computer to the microcomputer's entire functional system circuits (CPU, ROM, RAM, input/output interface circuits, as well as other auxiliary circuits) are all assembled on a printed circuit board, and then printed circuitry will be connected to the various functional chips.
Microcontroller is an integrated circuit chip with CPU, program memory, data memory, input/output interface circuits, timer/counter, interrupt controller, analog/digital converter, digital/analog converter, modem and other components.
Personal computer system software consists of a set of programs that control the computer system and manage its resources. Its main functions include starting the computer, storing, loading and executing application programs, sorting and retrieving files, and translating program language into machine language.
2, application:
Single board computer due to the small size, low cost and other characteristics, a large number of life equipment used in the modernization. Like our daily life in the smart appliances, cars and so on.
Single board computer is used in energy saving control, intelligent voice devices, alarm control, medical equipment and so on.
Personal computers are divided into desktops, all-in-one computers, laptops, handheld computers, tablet computers. , which is currently the fastest growing field, widely used.
3, the nature of the aspect:
Single-board computer will be all parts of the computer are assembled on a printed circuit board, including microprocessor / memory / input and output interfaces, and a simple seven-segment light-emitting diode display, a small keyboard, sockets and other external equipment.
Microcontroller for an integrated circuit chip, the use of ultra-large-scale integrated circuit technology with data processing capabilities of the central processor CPU, random memory RAM, read-only memory ROM, a variety of I / O port and interrupt system, timer / counter and other functions (integrated into a piece of silicon composed of a microcomputer system.
There are many types of personal computers, which are categorized as desktop, all-in-one, laptop, PDA, and tablet.

Expanded Information:
Single board computer assembles all parts of a computer on a single printed circuit board, including microprocessor/memory/input/output interfaces, and other external devices such as a simple seven-segment light-emitting diode display, a small keyboard, and sockets. Functions stronger than a microcontroller, suitable for production process control
The characteristics of the microcontroller can be summarized in the following areas: high integration; large storage capacity; external expansion capabilities; control functions. With a high degree of integration, reliability is relatively strong, even if the microcontroller is in a long period of time there will be no failure problems.
