Hostoperatsioonisüsteem

Hostoperatsioonisüsteem is a term used in computing to describe the primary operating system running on a physical machine, often referred to as the host. This is the system that directly interacts with the hardware components such as the CPU, memory, and storage devices. When virtualization is employed, the host operating system serves as the foundation upon which virtual machines are created and run. It manages the underlying hardware resources and allocates them to the various virtual environments. Examples of common host operating systems include Windows, macOS, and Linux distributions like Ubuntu or Fedora. The host operating system is crucial for the stable and efficient operation of any virtualized infrastructure, as it provides the necessary platform for the hypervisor or other virtualization software to function. Without a robust host operating system, the performance and reliability of the virtual machines running on top of it would be significantly compromised. In essence, it acts as the gatekeeper and manager of the physical resources that all other software, including guest operating systems within virtual machines, will depend on.
