Study Notes
File System Definition
- A file system is a way to organize and store files on a computer
- It provides a hierarchical structure for storing and retrieving files
- A file system consists of files, directories, and metadata
File System Components
- Files: collections of data stored on a disk
- Directories (or folders): containers that hold files and other directories
- Metadata: information about files and directories, such as permissions, ownership, and timestamps
File System Types
- Local File Systems: stored on local devices, such as hard drives or solid-state drives
- Network File Systems: stored on remote devices, accessed over a network
- Distributed File Systems: stored across multiple devices, providing a single file system interface
File System Operations
- Create: create a new file or directory
- Delete: remove a file or directory
- Read: retrieve the contents of a file
- Write: modify the contents of a file
- List: retrieve a list of files and directories in a directory
- Search: find files and directories based on specific criteria
File System Structures
- Hierarchical Structure: files and directories organized in a tree-like structure
- Flat Structure: files stored in a single directory with no subdirectories
File System Implementations
- FAT (File Allocation Table): a simple file system used in early operating systems
- NTFS (New Technology File System): a more advanced file system used in Windows operating systems
- HFS (Hierarchical File System): a file system used in macOS operating systems
- EXT (Extended File System): a file system used in Linux operating systems
File System Features
- Permissions: control access to files and directories based on user identity and permissions
- Access Control Lists (ACLs): fine-grained control over file and directory access
- File Compression: reduce the size of files to conserve storage space
- File Encryption: protect files from unauthorized access
- Journaling: record file system metadata to ensure file system integrity in case of a failure
