The correct answer is: B. share hardware resources with many programs simultaneously.
A multiprogramming system is a computer system that allows multiple programs to run simultaneously. This is done by sharing the computer’s hardware resources, such as the CPU, memory, and disk storage, among the different programs.
There are several advantages to using a multiprogramming system. First, it allows users to run multiple programs at the same time, which can save time. Second, it can improve the performance of programs that are CPU-intensive, by allowing them to run on multiple CPUs at the same time. Third, it can improve the performance of programs that are memory-intensive, by allowing them to use more memory than would be available if only one program were running at a time.
There are also some disadvantages to using a multiprogramming system. First, it can lead to increased overhead, as the operating system has to manage the sharing of resources among the different programs. Second, it can lead to increased contention for resources, as multiple programs may be trying to access the same resource at the same time. Third, it can lead to increased complexity, as the operating system has to be able to handle the complex interactions between the different programs.
Overall, multiprogramming systems offer a number of advantages, but they also have some disadvantages. The decision of whether or not to use a multiprogramming system depends on the specific needs of the application.
Here is a brief explanation of each option:
- Option A: A multiprogramming system does not necessarily run very fast. The speed of a multiprogramming system depends on a number of factors, such as the speed of the hardware, the efficiency of the operating system, and the number of programs that are running simultaneously.
- Option B: A multiprogramming system does share hardware resources with many programs simultaneously. This is one of the key features of a multiprogramming system.
- Option C: A multiprogramming system does not necessarily compute many programs simultaneously. The number of programs that can be run simultaneously depends on a number of factors, such as the speed of the hardware, the efficiency of the operating system, and the amount of memory available.
- Option D: A multiprogramming system does not use many operating systems. A multiprogramming system uses a single operating system that manages the sharing of resources among the different programs.
- Option E: None of the above is the correct answer.
