wear levelling ensures that different areas of the address range are used for writes and or erases in rotation to extend flash life (损耗平衡确保将地址范围的不同区域轮流用于写和或擦除操作以延长闪存设备的寿命。)
later, i ll show you how to use address ranges to control which lines a command is applied to-but in the absence of addresses, a command is applied to 我将在后面为您演示如何使用地址范围来控制将命令应用到哪些行--但是,如果不使用地址,命令将应用到
programs that connect to ip addresses in the loopback address range may not work as expected and you may receive an error message indicating you cannot establish a connection 连接到环回地址范围内的ip地址的程序可能无法正常工作,您可能会接收到错误消息,指明无法建立连接。
