The Palm Operating System for palm handheld computers is a good example of a modern single-user, single-task operating system. This is the most common type of operating system used on a home computer as well as on computer in offices and other work environments. Single User Operating system is designed to manage computer so that only one user can work on it at a time. MS-DOS, Windows 8/10 etc. are the examples of single-user operating system.

Multi-user operating system is designed to manage computer so that many users can work on it at a time. Many computers are connected to network through one operating system. So operating system coordinates and controls all computers connected to network. Mainframe computer uses multiuser operating system.
