+    Unix-based systems expose hardware to user space by means of special files,all created 
+    in the /dev directory upon device registration with the system.Programs willing to 
+    access a given device must locate its corresponding device file in /dev and perform the 
+    appropriate system call on it,which will be redirected to the driver of the underlying
+    device associated with that special file.Though system calls redirection is done by an 
+    operating system,what system calls are supported depends on the type of device and the 
+    driver implementation.

+    Unix-like 系统通过特殊文件将硬件暴露给用户空间，这些文件在设备注册到系统时全部创建于 /dev 目录下。
+    希望访问特定设备的程序必须在 /dev 中找到对应的设备文件，
+    并在其上执行适当的系统调用，该调用将被重定向到与该特殊文件关联的底层设备的驱动程序。
+    虽然系统调用的重定向是由操作系统完成的，但支持哪些系统调用则取决于设备的类型和驱动程序的实现。
