QuickTime is the standard media player in OS X systems. QuickTime can record a movie from your camera, and it can also record audio from a microphone or record the screen of your Mac.
The options are accessed by selecting File > New Movie Recording. To change the recording settings, click the arrow next to the Record button. Then choose your camera, microphone, and recording quality.
Quicktime has previously also been able to record the screen from mobile Apple devices (iPad or iPod), but in recent OS updates, the option for screen recording on mobile devices has been built in directly. A tutorial can be found here.
Important notice: QuickTime has previously been available for Windows OS, but Apple has ceased all support of QuickTime for Windows. Running QuickTime on Windows OS now poses severe security risks and is strongly discouraged.
The application is included in Mac OS X devices.
