Addressability refers to the ability of any device or program to access some random access memory.

Aggregation Collection if things.

Aligned is the way data are arranged and accessed in a computer memory. A modern computer reads from or writes to a memory address in word-sized chunks (typically 4-bytes). If the data are stored at a memory offset equal to some multiple of this word size, it increases the system's performance due to the nature of CPU–memory interface. In case of cached memories, it would be beneficial to allocate memory aligned to cache lines. If an array is partitioned for more than one thread to operate on, having the sub-array boundaries unaligned to cache lines could lead to performance degradation.
