With iodide, the solvate $\ce{NaI \cdot 3(CH3)2CO}$ can be formed, in which each $\ce{Na+}$ is coordinated by 6 acetone ligands via oxygen lone pairs, and the $\ce{I-}$ ions fill in the gaps between these octahedral units, being surrounded by the methyl groups of the acetones.
Randomization is a sampling method used in scientific experiments. It is commonly used in randomized controlled trials in experimental research.
Virtualization is a technique used to create an execution environment for software that is similar to the one it was originally designed for, but on a different hardware or operating system. Virtualization can be achieved usually at two levels: operating system virtualization and hardware virtualization.
