bit-by-bit memory

基本解释

DB2 10 substantially increases the amount of virtual storage that can be addressed by moving most DB2 working memory from 32-bit to 64-bit.
通過將大部分 DB2 工作內存從 32 位遷移到 64 位，DB2 10 極大地提高了可以尋址的虛擬內存量。
Memory constrained -- The extra memory provided by 64-bit supports a better caching strategy, enabling the application to avoid expensive queries, and so on.
內存限制——64 位所提供的額外內存可以支持更好的緩沖策略，使得應用程序可以避免開銷很高的查詢，等等。
Their launch strategies involved upgrading their phones bit by bit - a better camera, a brighter screen or larger memory - so as to make the "new" device just a little more attractive.
這些廠家的發佈策略包括一點點地陞級（好一點的攝像頭，一塊更明亮的屏幕或是更大的內存），以使這個‘新’設備多一點吸引力。
