大数据时代是什么意思的?

英语翻译
请英语好的朋友帮助纠正一下我的英语翻译（中文仅供参考,不必完全一样）：
伴随大数据时代的到来,实时的数据在帮助决策的过程中变得越发重要,这令可穿戴设备的需求激增.无论是用于社交还是保健,可穿戴设备的触角也在广阔延伸.
With the advent of the era of big datasets,real-time data is becoming increasingly important in assisting the decision making process.This creates a surge in demand of wearable devices.Both for social and health care,influencing are broad extension of wearable devices.

1NB等于多少GB?
大数据时代来临 最牛B的储存容量单位是NB
请高手作答1NB等于多少GB?（是1024的几次方?）（必答才会有分）
本人由于数学较差且多年未用.（我初步算来是1NB=1024的7次方GB,不知是否有误?）
这样便于记忆.最好是高人能用一种方法（设计一个单词也可）让我们记住下面的关系.
下面附单位换算：
最小的基本单位是Byte,按顺序给出所有单位：bit、Byte、KB、MB、GB、TB、PB、EB、ZB、YB、DB、NB,
　　它们按照进率1024（2的十次方）来计算：
　　1Byte = 8 bit
　　1 KB = 1,024 Bytes
　　1 MB = 1,024 KB = 1,048,576 Bytes
　　1 GB = 1,024 MB = 1,048,576 KB = 1,073,741,824 Bytes
　　1 TB = 1,024 GB = 1,048,576 MB = 1,073,741,824 KB = 1,099,511,627,776 Bytes
　　1 PB = 1,024 TB = 1,048,576 GB =1,125,899,906,842,624 Bytes
　　1 EB = 1,024 PB = 1,048,576 TB = 1,152,921,504,606,846,976 Bytes
　　1 ZB = 1,024 EB = 1,180,591,620,717,411,303,424 Bytes
　　1 YB = 1,024 ZB = 1,208,925,819,614,629,174,706,176 Bytes
　　1 DB = 1024 YB = 1,237,940,039,285,380,274,899,124,224 Bytes
　　1 NB = 1024 DB = 1,267,650,600,228,229,401,496,703,205,376 Bytes
