Værtoperativsystemer

Værtoperativsystemer, also known as host operating systems, are the primary operating systems that run directly on the hardware of a computer. These are the familiar operating systems like Windows, macOS, and Linux distributions that users interact with daily. A værtoperativsystem manages the computer's resources, including the CPU, memory, storage, and input/output devices, and provides a platform for applications to run. It handles task scheduling, memory allocation, file system management, and network communication. When virtualization is employed, the værtoperativsystem is the one that hosts the virtual machine monitor (VMM) or hypervisor. The VMM then creates and manages one or more guest operating systems, which run on top of the værtoperativsystem, sharing the underlying hardware resources. This means the værtoperativsystem is crucial for the functioning of virtualized environments, as it provides the essential layer of abstraction and resource management that allows multiple operating systems to coexist and operate simultaneously on a single physical machine. Without a stable and efficient værtoperativsystem, the performance and reliability of guest operating systems would be severely compromised.
