What is the difference between Real time system and Multiprogrammed system?

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
01. Time Sharing is the logical extension of multiprogramming, in this time sharing Operating system many users/processes are allocated with computer resources in respective time slots.
Multiprogramming
01. Multiprogramming operating system allows to execute multiple processes by monitoring their process states and switching in between processes.
Time Sharing
02.Processors time is shared with multiple users that’s why it is called as time sharing operating system.
Multiprogramming
02.Processor and memory underutilization problem is resolved and multiple programs runs on CPU that’s why it is called multiprogramming.
Time Sharing
3. In time sharing OS system depends on time to switch between different processes.
Multiprogramming
3. In Multiprogramming OS, system depends on devices to switch between tasks such I/O interrupts etc.
Time Sharing
4. System model of time sharing system is multiple programs and multiple users.
Multiprogramming
4. System model of multiprogramming system is multiple programs.
Time Sharing
5. In this process, two or more users can use a processor in their terminal.
Multiprogramming
5. In this, the process can be executed by a single processor.
Time Sharing
**6.**Time sharing OS has fixed time slice.
Multiprogramming
7. Multi-programming OS has no fixed time slice.
Time Sharing
**8.**Time sharing system maximizes response time.
Multiprogramming
8. Multiprogramming system maximizes response time.
Time Sharing
9. Example: Windows NT.
Multiprogramming
9. Example: Mac OS.

Difference between manual system and automated system in system analysis and design?
A manual system analysis require individuals to supply input directly into a system designed to simulate real life events. An automated system is controlled by technology to automatically supply input.
What is the difference between an elastomer and plastics?
There isn't too much of a difference between elastomers and plastics. The only real difference between them is how far you can stretch them. Other than that they are really similar.
What is relation between settling time and real roots of a system?

Difference between conventional OS and embedded OS?
Conventional OS aim to give users the ability to run other software that are interactive in nature to perform different tasks. On the other hand, embedded OS only run fixed set of tasks and deliver the expected results in real time.
