Server Bandwidth-related

Mbps, Mbit/s, MB/s common sense literacy

Easy to confuse several concepts: Mbps, MB/s, MB/s.

1, we often hear that such IDC provides server access bandwidth is 10M exclusive, or 100M sharing and other data. What is the concept of 10M and 100M here?
The so-called 10M bandwidth, in fact, refers to 10Mbps (megabits), that is, 1.25mb/s, but this is only the theoretical speed, in fact, but also minus the loss. According to this argument, the fastest download speed for 10M bandwidth is 1.25mb/s,100m bandwidth the fastest download speed is 12.5mb/s.

2, on the above we have access to MB/s, then MB/s and MB/sec What is the difference?
The meaning of MB/s is megabytes per second, MB/s means megabits per second, the former refers to the number of bytes transmitted per second, the latter refers to the number of bits transmitted per second. The two are completely different. Byte is the number of bytes, bit is the number of bits, in the computer every eight bits is a byte, that is 1byte=8bit, is 1:8 correspondence. So 1mb/s equals 8mb/s. So in the writing unit must pay attention to the case of B-letter, at this time the size of the B-letter can really be called near misses, great difference.
In the official data (e.g., the telecommunications sector), MB/s or kb/s are generally used for the data transfer rate.
and download software (ie, thunder, Express) generally use MB/s or kb/s units.

Self-Summary:

The difference between MB/s and MB/s
MB/s: Megabytes per second
MB/s: Megabits per second

BYTE: Byte bit: The number of bits, every eight bits of the computer is a byte, 1byte=8bit, therefore, 1mb/s=8mb/s, so in writing must pay attention to the case of B-letter
