Linux File System Architecture and Key Components
Understanding Linux File Management Subsystem
The Linux File Management Subsystem, an integral part of the Linux kernel and user space, meticulously handles all aspects related to files. This includes their creation, storage, retrieval, permissions, and overall structure. Its primary role is to ensure that data is stored efficiently and securely on disk, remaining readily accessible whenever needed.
Core Components of Linux File Management
File System Interface
- Provides system calls such as
open()
,read()
,write()
, andclose()
, which user programs utilize to interact with files. - Abstracts the underlying complexity of physical storage devices.
Virtual File System (VFS)
- Acts as a crucial abstraction layer, offering a common interface to various file
