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 full form of IO.sys?
The full form of IO.sys is "Input/Output System." It is a critical system file in DOS and Windows operating systems that handles low-level input and output operations during the boot process. IO.sys is responsible for managing hardware communication, including disk drives and other peripherals, essential for loading the operating 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 a virtual machine appear to a hypervisor?
A virtual machine (VM) appears to a hypervisor as a self-contained, isolated environment that operates like a physical computer. The hypervisor manages the VM's resources, including CPU, memory, and storage, by allocating these resources from the host system to the VM as needed. Each VM has its own virtual hardware, which is simulated by the hypervisor, allowing multiple VMs to run concurrently on the same physical machine without interference. This abstraction enables efficient resource utilization and enhanced flexibility in managing workloads.
What is program allows separate partitions of a single server to support a different operating system Question 9 options?
The program that allows separate partitions of a single server to support different operating systems is called a hypervisor. Hypervisors enable virtualization by creating and managing multiple virtual machines (VMs), each capable of running its own operating system independently. There are two types: Type 1 (bare-metal) hypervisors run directly on the hardware, while Type 2 (hosted) hypervisors run on top of an existing operating system. Examples include VMware ESXi, Microsoft Hyper-V, and Oracle VirtualBox.
