Comparison of supercapacitors, common capacitors and batteries Voltage The supercapacitor has a recommended operating voltage or optimum operating voltage, which is determined based on the maximum operating time of the capacitor at the highest set tempera
The principle and resistance relationship of the ntc thermistor The principle of the ntc thermistor: The ntc thermistor will be in a non-operating state for a long time; when the ambient temperature and current are in the c-zone, the heat-dissipating
一、虚拟化 为了让用户告诉操作系统如何利用虚拟机功能，OS提供给应用程序一些接口——系统调用，也会说提供了一个标准库。 CPU通过分时达到虚拟化。 内存物理模型只是一个字节数组，读写修改需要制定地址。程序的所有数据结构以及使用的指令都在内存。OS虚拟化内存，让每个进程都访问自己
