File System
Domain: Computer Systems
🎯 Motivation
How files are organized on storage: directories, files, permissions. The OS manages this.
📋 Concrete Example
File system: /home/user/documents/essay.txt. Directories (folders) contain files and subdirectories. Permissions: who can read, write, or execute each file.
🔗 Analogy
The file system is like a filing cabinet - drawers (directories) contain folders (subdirectories) which contain documents (files). Each document has permissions: who can read or edit it.
