KVM (KERNEL-BASED VIRTUAL MACHINE)
KVM is a virtualization technology built into the Linux kernel. It allows a host computer to run multiple, isolated guest virtual machines, each with its own operating system.
Analogy: If a computer is a house, KVM adds rooms (VMs) that can be rented out to different guests (operating systems) while still being managed by the owner (host OS).
Why It Matters: KVM is known for its performance, security, and tight integration with Linux, making it a popular choice for virtualization.
