File management
- A file stores binary data.
- A file has an extension which indicates the operating system which application to load the file using.
The file management may represent the files in a logical structure.
User management/security
User management allows multiple users to log into the same computer, with the operating system retaining settings.
Each user may have different access rights and a client-server network may impose a fixed or roaming profile for a user and manage login requests to the network.
User interfaces
