The memory requirements of individual data structures might get altered, depending upon the way packing is implemented in the compiler.

个别数据结构的内存需求可能会发生改变，这依赖于编译器中实现对齐的方式。

This is achieved by packing more data into smaller memory footprint, thereby giving space for storing more data.

这是通过将更多数据压缩到更小的内存空间中实现的，从而留出空间存储更多数据。

Data compression addresses the mechanics of packing down information without losing meaning.

FORBES: Density Of Meaning: Creation As The Flip Side Of Memory

The secret to packing that much information on such small real estate--about 15 times denser than the densest data storage device currently in existence--is self-assembly, or tricking the disk's materials into organizing into an array of data-storing dots packed far tighter than what could be accomplished with current techniques.
