The calculation method of broadband:
In computer theory, bit is the smallest unit of information that is bits, 0 and 1, respectively. Byte, which is a byte consisting of 8bit, is 1byte. The conversion relationship is that the 1b=8b,b represents byte, and the lowercase b is the bit meaning. And the broadband calculation method is expressed in bps, that is, no seconds to pass the number of bits of information. Its conversion formula:
1b=8b 1b/s=8b/s (or 1bps=8bps)
1kb=1024b 1kb/s=1024b/s
1MB=1
between B and B.2. What is the download speed of 2 Mbps?
First:2 m/s = (2*(10 ^ 6)/8 B/S = 250000 B/S
Explanation: we need to convert the 2 Mbit/s network
