M、G都來自英語mega giga的首字母.
kilo (k)* = 10 ^ 3 = 1,000 thousand 千
mega (M) = 10 ^ 6 = 1,000,000 million 百萬
giga (G) = 10 ^ 9 = 1,000,000,000 billion 十億
tera (T) = 10 ^ 12 = 1,000,000,000,000 trillion 萬億
在計算機/通訊行業(yè)中,計算數(shù)據(jù)傳送速度也使用每秒傳送公制數(shù)據(jù)量來計算
1 bit (b) = 0 or 1 = one binary digit 一個二進制位元
1 kilobit(kb)=10^3 bits = 1,000 bits 一千位元
1 Megabit(Mb)=10^6 bits = 1,000,000 bits 一百萬位元
1 Gigabit(Gb)=10^9 bits = 1,000,000,000 bits 一萬億位元
再有幾年G不夠用就開始用T了
1T＝1000G
1G＝1000M
1M＝1000k
