The '''Quick Emulator''' ('''QEMU''')<ref>{{cite web |title=Glossary |url=https://csrc.nist.gov/glossary/term/qemu |access-date=2023-04-24 |website=National Institute of Standards and Technology}}</ref> is a [[free and open-source]] [[emulator]] that uses dynamic [[binary translation]] to emulate a [[computer]]'s [[Central processing unit|processor]]; that is, it translates the emulated binary codes to an equivalent binary format which is executed by the machine. It provides a variety of hardware and device models for the virtual machine, enabling it to run different [[guest operating system]]s. QEMU can be used with a [[Kernel-based Virtual Machine]] (KVM) to emulate hardware at near-native speeds. Additionally, it supports [[User space and kernel space|user-level processes]], allowing applications compiled for one processor architecture to run on another.<ref name="hoxLZ3">{{cite web |last=Speed |first=Richard |date=2019-04-25 |title=QEMU 4 arrives with toys for Arm admirers, RISC-V revolutionaries, POWER patriots... you get the idea |url=https://www.theregister.co.uk/2019/04/25/qemu_4/ |url-status=live |archive-url=https://archive.today/20191001070134/https://www.theregister.co.uk/2019/04/25/qemu_4/ |archive-date=2019-10-01 |access-date=2019-10-01 |website=www.theregister.co.uk |publisher=[[The Register]] |language=en}}</ref>

QEMU supports the emulation of [[x86]], [[ARM architecture family|ARM]], [[PowerPC]], [[RISC-V]], and [[QEMU#Emulated hardware platforms|other architectures]].
