摘　　要：相比Windows操作系统而言,原代码开放、自由免费、支持SWP和NUMA体系结构,支持平台最多的Linux操作系统自1991年诞生以来,便具有无可取代的优势,目前广泛应用于嵌入式系统和服务器上。同时其多用户多任务的特性可以为用户量身定做适合的功能,从而灵活应用在各种场合。虽然在早期系统中用户界面方面不如Windows操作方便,主要采用字符界面键入命令,但现在的系统大多数也采用图形化界面深受用户喜爱。文件系统是Linux的一个突出特色,本文以Linux的典型文件系统ext2为例,介绍该文件系统的组成及工作原理,同时设计了简单的模拟实现文件系统简单的功能。Compared with the Windows operating system, the original code open, free, free support for SWP and NUMA architecture, support platform most Linux operating system since its birth in 1991, it has the irreplaceable advantages, is widely used in the embedded system and servers.The characteristics of the multi-user multiple tasks at the same time the function that can suit tailored for the user, thus flexible application in various occasions.Although in the early system is behind the Windows user interface easy to operate, mainly USES the character type the command interface, but now most also USES a graphical interface are popular among users.File system is a prominent feature of Linux, however based on the typical Linux file system as an example, introduces the composition and working principle of the file system, and design a simple simulation can realize the function of simple file system.
