An operating system (OS) is the program that, after being initially loaded into the computer by a boot program, manages all of the other application programs in a computer. The application programs make use of the operating system by making requests for services through a defined application program interface ( API ).

VMware ESXi (formerly ESX) is an enterprise-class, type-1 hypervisor developed by VMware, a subsidiary of Broadcom, for deploying and serving virtual computers.As a type-1 hypervisor, ESXi is not a software application that is installed on an operating system (OS); instead, it includes and integrates vital OS components, such as a kernel. A virtual computer system is known as a “virtual machine” (VM): a tightly isolated software container with an operating system and application inside. Each self-contained VM is completely independent. Putting multiple VMs on a single computer enables several operating systems and applications to run on just one physical server, or “host.” A virtual machine is a computer file, typically called an image, that behaves like an actual computer. It can run in a window as a separate computing environment, often to run a different operating system—or even to function as the user's entire computer experience—as is common on many people's work computers.What is a virtual machine?

Enabling virtualization gives you access to a larger library of apps to use and install on your PC. If you upgraded from Windows 10 to Windows 11 on your PC, these steps will help you enable virtualization.

Each process stores data and code in address space of memory and is mapped onto the virtual address space by the OS to keep track of it. The OS addresses virtual memory and uses the CPU to interface with the physical memory. Windows 10 virtual memory is limited only by the address space available on the computer's architecture.VMOS is an APP software based on Virtual Machine. VMOS can be installed in the form of a normal APP to Linux or Android system through VM technology. That is to run another complete Android system through an application and is out of control of the host system.Host OS: Also known as primary OS, it is installed directly on the physical hardware of the computer.

Within this …A guest operating system is a piece of software that runs inside a virtual computer. A host operating system is a piece of software that runs on a computer and connects with the hardware. Resource Management: the guest operating system is responsible for managing its own resources inside the virtual machine.Hyper-V lets you run multiple operating systems as virtual machines on Windows. Hyper-V specifically provides hardware virtualization. That means each virtual machine runs on virtual hardware. Hyper-V lets you create virtual hard drives, virtual switches, and a number of other virtual devices all of which can be added to virtual machines.The technique is exploited by a computer’s operating system (OS) in situations when the system lacks sufficient RAM to execute instructions. With virtual memory, computers can run complex and sophisticated programs as the conflicting memory demands of multiple programs are met within a fixed memory space.
