QEMU

QEMU, short for Quick EMUlator, is an open-source, cross-platform emulator and virtualization software that allows you to run a wide range of operating systems and virtual machines on your computer. It lets you create virtual machines on your existing hardware, run multiple operating systems simultaneously, and test applications and software in different environments without the need for additional hardware. QEMU is available for most of the popular platforms including Windows, Linux, macOS, and FreeBSD.

With QEMU, you can create and run virtual machines that emulate different hardware architectures, such as x86, ARM, MIPS, and PowerPC, among others. You can also configure various hardware components within the virtual machine, such as storage, networking, graphics, and memory. QEMU's unique feature is its ability to emulate a complete system, which means it can run an entire operating system without requiring any modifications or drivers.

In summary, QEMU is a versatile and powerful emulator and virtualization software that allows you to run multiple operating systems and virtual machines on your computer. Its cross-platform support and the ability to emulate different hardware architectures make it a popular choice for developers, system administrators, and enthusiasts.
