An emulator is a software that allows one computer system (called the host) to behave like another computer system (called the guest). Emulators are used to run software or operating systems that were originally designed for a different type of computer or operating system. For example, an emulator can be used to run Windows software on a Mac computer, or to run Android apps on a Windows computer.
