信息管理是操作系统的一个重要的功能，主要是向用户提供-个文件系统。 -般说，-个文件系统向用户提供创建文件,撤销文件，读写文件，打开和关闭文件等功能。有

了文件系统后，用户可按文件名存取数据而无需知道这些数据存放在哪里。这种做法不仅便于用户使用而且还有利于用户共享公共数据。此外,由于文件建立时允许创建者

规定使用权限，这就可以保证数据的安全性。

处理机管理。处理机是计算机中的核心资源，所有程序的运行都要靠它来实现。如何协调不程序之间的运行关系，如何及时反应不同用户的不同要求，如何让众多用户能够公平地得到计算机的资源等都是处理机管理要关心的问题。具体地说处理机管理要做如下事情:对处理机的时间进行分配，对不同程序的运行进行记录和调度，实现用户和程序之间的相互联系，解决不同程序在运行时相互发生的冲突。处理机管理是操作系统的最核心部分，它的管理方法决定了整个系统的运行能力和质量，代表着操作系统设计者的设计观念。

Information management is an important function of the operating system, mainly providing users with a file system- Generally speaking, a file system provides users with functions such as creating files, revoking files, reading and writing files, and opening and closing files. have

After creating a file system, users can access data by file name without knowing where the data is stored. This approach is not only convenient for users to use, but also beneficial for users to share public data. In addition, as the creator is allowed to create the file

By specifying usage permissions, data security can be ensured.

Processor management. The processor is the core resource in a computer, and all programs rely on it to run. How to coordinate the running relationship between different programs, how to respond to the different requirements of different users in a timely manner, and how to ensure that many users can fairly access computer resources are all issues that processor management should be concerned about. Specifically, processor management needs to do the following: allocate processor time, record and schedule the operation of different programs, establish mutual connections between users and programs, and solve conflicts that occur between different programs during runtime. Processor management is the most core part of the operating system, and its management methods determine the operational capability and quality of the entire system, representing the design concept of the operating system designer.
