This article mainly introduces "what are the functions of the server file system". In the daily operation, I believe that many people have doubts about the functions of the server file system. The editor consulted all kinds of materials and sorted out the simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts about "what are the functions of the server file system?" Next, please follow the editor to study!

From the user's point of view, the main purpose of introducing the file system is to access the file by name; users can access the file as long as they know the file name, regardless of where the file is stored on disk.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

From the user's point of view, the main purpose of introducing the file system is to access files by name.

A file system is a method and data structure used by the operating system to identify files on storage devices (usually disks, but also NAND Flash-based solid state drives) or partitions; that is, methods of organizing files on storage devices.

The software organization responsible for managing and storing file information in the operating system is called the file management system, referred to as the file system.

From the system point of view, the file system is a system that organizes and allocates the space of file storage devices, is responsible for file storage and protects and retrieves stored files. Specifically, it is responsible for creating files for users, modifying files, accessing files, transferring files, deleting files that users do not need, and so on.

From the user's point of view, the file system implements "access by name". As long as you know the file name, you can access the file, regardless of where the file is stored on disk.

The most important thing in the file system is its representation in the eyes of the user, that is, what the file consists of, how to name the file, how to protect the file, and what operations can be done on the file. details such as how many sectors are in a logical block are not of concern to the user.

When the process creates a file, it names the file. When the process terminates, the file still exists, and other processes can access it through this file name.

The features of the file system include:

Manage and schedule the storage space of the file, provide the logical structure, physical structure and storage method of the file, realize the mapping of the file from the identification to the actual address, realize the control operation and access operation of the file, realize the sharing of file information and provide reliable file secrecy and protection measures, and provide file security measures.

The logical structure of a document is to organize the file structure according to the logical relationship of the content of the document. The logical structure of files can be divided into streaming files and recording files.

Streaming file: the data in the file is a string of character streams and has no structure.

Record file: consists of several logical records, each of which consists of the same data item, the length of which can be fixed or uncertain.

At this point, the study on "what are the functions of the server file system" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
