Multiprograming system is that system in which multiple programs run at same time or simontaniously for example windows xp.in this system does not provide user interaction with the coputer system. But time sharing systemis that provide user interaction with system and user thinks that system is with him all the time.
time sharing operating system is user interactive, but multiprogramming operating system need not be user interactive
A hard real-time system guarantees that critical tasks complete on time. This goal requires that all delays in the system be bounded from the retrieval of the stored data to the time that it takes the operating system to finish any request made of it. A soft real time system where a critical real-time task gets priority over other tasks and retains that priority until it completes. As in hard real time systems kernel delays need to be bounded

Time-sharing and multiprogramming have various differences. However, these two environments share the feature whereby several users can use the system at the same time.
the main difference b/w multiprogramming and multiprocessing O.S. is that the previous one is non-interactive O.S. and the later is interactive O.S. By-Satyam Maheshwari
The main difference between batch sharing and time sharing is that in batch sharing system tasks are processed in order in which they arrive. Whereas, in the later the system switches between tasks.
By time sharing and using proper job mix
Operating System level.
THE multiprogramming system was created in 1968.
Yes, it is possible to support time-sharing without multiprogramming, though it would be highly inefficient. Time-sharing systems can allocate CPU time to a single process in a way that allows multiple users to interact with the system simultaneously, but without multiprogramming, only one user process would execute at a time. This approach would lead to significant idle time and poor resource utilization, undermining the benefits of a time-sharing system. Ultimately, multiprogramming enhances the efficiency and responsiveness of time-sharing by allowing multiple processes to coexist and utilize CPU time effectively.
The problems are created by several users share the time-sharing and multiprogramming system. So I think the created security problems are:
multiprogramming-there is no way for single user to keep either cpu or the io divices busy at all times...
