Final answer:
The statement is incorrect; in a multiprogramming system, the main memory is shared among multiple processes to maximize efficiency, and the operating system manages this sharing through memory allocation techniques.
Step-by-step explanation:
In the context of a multiprogramming system, the main memory is typically shared among multiple processes. This is a fundamental aspect of multiprogramming, allowing the system to use the available memory efficiently by allocating it to various processes as needed.
The operating system manages the memory allocation to ensure that each process has enough memory to execute and that the memory is utilized to its full capacity, preventing any part of it from being wasted.
Multiprogramming systems are designed to maximize resource utilization by running several processes concurrently. The operating system's memory manager assigns blocks of memory to each process, using techniques such as paging or segmentation, and ensures that the processes do not interfere with each other by providing memory protection mechanisms.
By allowing multiple programs to reside in memory at the same time, multiprogramming increases the system's overall efficiency, leading to better performance and increased throughput for the system.
