The correct answer is C. decreased operating-system overhead.
Multiprogramming is a technique that allows multiple programs to run simultaneously on a single computer. This can be done by time-sharing, which means that each program is given a small amount of time to run, and then the operating system switches to another program. This process is repeated very quickly, so it appears that all of the programs are running at the same time.
Multiprogramming has several advantages. First, it can increase throughput, which is the number of jobs that can be completed in a given amount of time. This is because multiple programs can be running at the same time, so they can all make progress towards completion.
Second, multiprogramming can reduce response time, which is the amount of time it takes for a program to respond to a user request. This is because the operating system can switch to a program that is waiting for input or output, rather than having to wait for the current program to finish running.
Third, multiprogramming can improve resource utilization. This is because multiple programs can use the same resources, such as the CPU, memory, and disk storage. This can help to ensure that these resources are not wasted.
Fourth, multiprogramming can make the system more responsive to users. This is because users can interact with multiple programs at the same time, rather than having to wait for one program to finish before they can start another.
However, multiprogramming also has some disadvantages. First, it can increase the complexity of the operating system. This is because the operating system has to manage multiple programs, which can be difficult to do.
Second, multiprogramming can lead to increased overhead. This is because the operating system has to switch between programs, which takes time.
Third, multiprogramming can lead to decreased performance. This is because the operating system has to share the resources between multiple programs, which can slow down each program.
Overall, multiprogramming has both advantages and disadvantages. The decision of whether or not to use multiprogramming depends on the specific needs of the system.
