The maximum delay required for two consecutive clicks to be interpreted as a double-click is not standardized. According to Microsoft's MSDN website, the default timing in Windows is 500 ms (half a second). [6] The double-click time is also used as a basis for other timed actions.

Internal view of a Macintosh LC. The LC uses a "pizza box" case with a Processor Direct Slot (PDS) but no NuBus slots. It has a 16 MHz Motorola 68020 microprocessor which lacks a floating-point coprocessor (although one could be added via the PDS). The LC has a 16-bit data bus, which is a major performance bottleneck as the 68020 is a 32-bit CPU.
