Why do modern operating systems use preemptive multitasking?

Modern operating systems use preemptive multitasking to enhance user interactivity and system responsiveness. It allows the operating system to interrupt a running process and switch the CPU to another process, ensuring that all processes receive appropriate attention and that the system remains responsive to user inputs.
A computer is in System mode when: When does a deadlock occur in a system? Which memory management scheme allows the physical address space of a process to be non-contiguous? Which is better, Time slicing or time sharing? Why do modern operating systems use preemptive multitasking? What is the main purpose of a context switch in an operating system? Where is the Page Table typically stored in a computer system? When is the "thrashing" condition likely to occur in a system using virtual memory? How to resolve the critical section problem in concurrent programming? Which of the following are/is true? What mechanism does an operating system use to handle the execution of multiple processes that require frequent access to the CPU?
