A single-user system typically does not support multiprogramming in the traditional sense, as it is designed for one user to run one program at a time. However, some single-user systems may implement a form of multitasking, allowing multiple processes to reside in memory and switch between them, but only one process is actively using the CPU at any given moment. In contrast, multiprogramming generally refers to a system's ability to run multiple programs concurrently, optimizing CPU usage by overlapping I/O operations with processing. Thus, while there may be some overlap, true multiprogramming is more characteristic of multi-user or multi-tasking systems.
MS-DOS supports multiprogramming to some extent.-
THE multiprogramming system was created in 1968.

Yes, UNIX supports multiprogramming, allowing multiple processes to run concurrently. This capability enables efficient resource utilization by sharing the CPU among various tasks, improving system performance and responsiveness. UNIX achieves this through process scheduling and management, ensuring that processes can execute simultaneously without interference.
Multiprogramming System: In multiprogramming system the same memory is shared by different number of programmes. MultiUser system: More than one user can use the system at a time.There will one centralized server and the users connected with the system are called as dump terminals.

It supports multiprogramming since multiple processes can be stored inside the main memory.
Multiprogramming is collecting several jobs in a job pool and the OS selects the job from the pool so that the CPU has one job to execute , in case of any IO request for the job in execution the CPU switches to another job here switching is less compared to multitasking.So a computer system which allows such type of switching in between jobs is called a multiprogramming system. Please make note that multitasking is done by user but multiprogramming is done by operating system only.
