What role does a hypervisor play in managing virtual machines within an operating system environment?
A hypervisor is a software that creates and manages virtual machines within an operating system. It acts as a mediator between the physical hardware and the virtual machines, allowing multiple operating systems to run on a single physical machine. The hypervisor allocates resources, such as CPU, memory, and storage, to each virtual machine, ensuring they operate efficiently and securely.

How does process management operate within an operating system?
Process management within an operating system involves handling and coordinating tasks or processes running on the computer. This includes creating, scheduling, and terminating processes, as well as managing resources like memory and CPU usage. The operating system ensures that processes run efficiently and do not interfere with each other, ultimately optimizing the overall performance of the system.
What is the purpose and functionality of an inverted page table in operating systems?
An inverted page table in operating systems is used to map virtual memory addresses to physical memory addresses. It helps in efficiently managing memory by allowing multiple virtual pages to be mapped to a single physical page. This helps in reducing memory overhead and improving performance by avoiding the need for a separate page table for each process.
Why must a computer start in kernel mode when power is switched on?
Because a kernel is the main component of most computer operating system,it is bridge between application and the actual data processing done at hardware level .The kernel responsibility include managing the system resources. sanjjit------thank you
How does multi-level paging impact system performance and memory management in operating systems?
Multi-level paging in operating systems can improve system performance by reducing the time needed to access memory. It does this by breaking down the page table into smaller, more manageable parts, which allows for faster lookups. Additionally, multi-level paging can help with memory management by efficiently organizing and managing memory resources, leading to better utilization of available memory.
