大数据需要特殊的技术,以有效地处理大量的容忍经过时间内的数据。适用于大数据的技术,包括大规模并行处理(MPP)数据库、数据挖掘、分布式文件系统、分布式数据库、云计算平台、互联网和可扩展的存储系统。最小的基本单位是bit,按顺序给出所有单位:bit、Byte、KB、MB、GB、TB、PB、EB、ZB、YB、BB、NB、DB。它们按照进率1024(2的十次方)来计算:1 Byte =8 bit,1KB= 1,024 Bytes = 8192 bit,1MB= 1,024 KB = 1,048,576 Bytes,1GB= 1,024 MB = 1,048,576 KB,1TB= 1,024 GB = 1,048,576 MB,1PB= 1,024 TB = 1,048,576 GB,1EB= 1,024 PB = 1,048,576 TB,1ZB= 1,024 EB = 1,048,576 PB,1YB= 1,024 ZB = 1,048,576 EB,1BB= 1,024 YB = 1,048,576 ZB,1NB= 1,024 BB = 1,048,576 YB,1DB= 1,024 NB = 1,048,576 BB全称:,1Bit(比特) =Binary Digit,8Bits= 1 Byte(字节),1,000 Bytes = 1 Kilobyte,1,000Kilobytes = 1 Megabyte,1,000 Megabytes = 1 Gigabyte,1,000 Gigabytes = 1Terabyte,1,000 Terabytes = 1 Petabyte,1,000 Petabytes = 1 Exabyte,1,000Exabytes = 1 Zettabyte,1,000 Zettabytes = 1 Yottabyte,1,000 Yottabytes = 1Brontobyte,1,000 Brontobytes = 1 Geopbyte
