Actually, the ZIP archive is all-in-one: it contains files for all supported platforms, including Windows, Mac OS X, and Linux. However, to ensure easiest installation and best user experience, it is strongly recommended to use a dedicated download option for these platforms instead: Windows bundle provides convenient installer and bundled JRE, Mac OS X - a Mac-style application, Linux - bundled Oracle JRE for x86/x64 which is superior to OpenJDK for UI applications.
