| 单词 | M |
| 释义 | M 1. Mega. From Greek megas, meaning great, translates to million. 2. In transmission systems, MHz (MegaHertz) is a million (106) Hertz, Mbps (Megabit per second) is a million (106) bits per second, and MBps (MegaByte per second) is a million (106) bytes per second. In transmission systems, therefore, a million is exactly 1,000,000, since the measurement is based on a base 10, or decimal, number system. 3. In computing and storage systems, a MB (MegaByte) is actually 1,048,576 (220) bytes, because the measurement is based on a base 2, or binary, number system.The term MB comes from the fact that 1,048,576 is nominally, or approximately, 1,000,000. |
