8. Double-precision floating-point format - Wikipedia

   en.wikipedia.org/wiki/Double-precision_floating...

   Double-precision floating-point format (sometimes called FP64 or float64) is a floating-point number format, usually occupying 64 bits in computer memory; it represents a wide dynamic range of numeric values by using a floating radix point. Double precision may be chosen when the range or precision of single precision would be insufficient.

9. User space and kernel space - Wikipedia

   en.wikipedia.org/wiki/User_space_and_kernel_space

   User space and kernel space. A modern computer operating system usually uses virtual memory to provide separate address spaces or separate regions of a single address space, called user space and kernel space. [1][a] Primarily, this separation serves to provide memory protection and hardware protection from malicious or errant software behaviour.
