Answer / Renu Saini
1. Real User ID (RUID): The user ID of the process when it was spawned.
2. Effective User ID (EUID): The user ID that the process is currently using for accessing system resources.
3. Saved Set-User-ID (SSUID): This ID is used when a program is executed with setuid permission, allowing it to run with the privileges of the owner.
4. Filesystem User ID (FSUID): The user ID that the process uses for accessing the file system.
5. Process User ID (PUID): The user ID that the kernel sees the process as.
