Programs on current computers do not run "directly on hardware". Instead, the hardware (in this case, a {{w|Central processing unit|processor}} of the {{w|x86-64}} architecture) is controlled by the {{w|operating system}} {{w|Kernel (computing)|kernel}} (in this specific case, {{w|XNU}} is the kernel used in Apple-branded devices). Many operating systems offer a standardized {{w|Interface (computing)|interface}} called {{w|POSIX}}, which wraps the services offered by the different operating systems so that applications do not need to cope with the differences between the operating systems. {{w|Darwin (operating system)|Darwin}} is the name of the core set of components on which the Apple's {{w|OS X}} operating system runs. And using this operating system, the user runs the {{w|Firefox}} web browser. However, the browser itself contains further abstraction layers: {{w|Gecko (layout engine)|Gecko}} is the engine handling the display of web pages on the screen, but in this case, it only allows a separate software, {{w|Adobe Flash Player}}, to render a video requested by the user. | Programs on current computers do not run "directly on hardware".
