常常听到人们会提起单位,之前的以MB和GB为主,以前一个128MB的U盘容量都觉得,哇,好大啊。现在U盘8G,16G,32G,64G都成主流了,笔记本都1TB了。
百度、阿里,以及腾讯这样的互联网巨头,其分析平台每天处理的数据量高达100PB,2011年全球数据总量为1.8ZB...新的单位很多。
那么我们具体来看一下各个单位之间大小究竟是怎么回事:
下面由小到大计数:
1bit 就是1位二进制数;
1Byte就是1个字节.1个字节是由8个二进制位组成的. 1Byte=8bit. 1B (byte 字节);
1KB(Kilobyte 千字节) = 2^10 B = 1024 B;
1MB(Megabyte 兆字节) = 2^10 KB = 1024 KB = 2^20 B;
1GB(Gigabyte 吉字节) = 2^10 MB = 1024 MB = 2^30 B;
1TB(Trillionbyte 太字节) = 2^10 GB = 1024 GB = 2^40 B;
1PB(Petabyte 拍字节) = 2^10 TB = 1024 TB = 2^50 B;
1EB(Exabyte 艾字节) = 2^10 PB = 1024 PB = 2^60 B;
1ZB(Zettabyte 泽字节) = 2^10 EB = 1024 EB = 2^70 B;
1YB(YottaByte 尧字节) = 2^10 ZB = 1024 ZB = 2^80 B;
1BB(Brontobyte ) = 2^10 YB = 1024 YB = 2^90 B;
1NB(NonaByte ) = 2^10 BB = 1024 BB = 2^100 B;
1DB(DoggaByte) = 2^10 NB = 1024 NB = 2^110 B;
如果全部换算成Byte:
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;
大数据时代,数据成海。 固有学富五车,才高八斗。
那些资料换成电子版,应当是很小了。现在学富5G,才高8T也无济于事。
创新,速度,才能智胜。
