Mbps(Mb/s)的含义是兆比特每秒,指每秒传输的位数量(小写b代表bit)
MB/s的含义是兆字节每秒,指每秒传输的字节数量(大写B代表Byte)
1Mbps(Mb/s)=1024*1024bit=1024*1024/8Byte=1024/8KB=128KB=1/8MB=0.125MB
即8Mbps=1MB/s
IEC标准规定如下
1Byte=8bit
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
