The so-called broadband is strictly speaking, it is able to meet the perception of the various media can feel the bandwidth needed to transmit the network, so it is also a dynamic, development concept. A relatively wide band. In digital communication, it is usually referred to as the bandwidth that transmits 2mbit/s signals above. Broadband Internet is the speed of broadband network, the higher the speed of your broadband, so download and upload the relative increase in the rate, so whether you play the game or open the page is relatively faster.
On the calculation of the speed, we must first distinguish between the kbytes/s and the kbits/s two units of the difference. In computer theory, bit is the smallest unit of information, is bits, respectively, 0 and 1,byte is the byte, 8bit can be composed of a byte is 1byte. The conversion relationship is 1byte=8bit, and the broadband calculation method is expressed in bps, that is, no seconds to pass how many bits of information. Its conversion formula:
1byte=8bit 1kbytes/s=8kbits/s (or 1bps=8bps)
1kb=1024b 1kb/s=1024b/s
1MB=1024KB 1mb/s=1024kb/s
2 trillion broadband, then your theory download the maximum speed is 2048/8=256kb/seconds, but due to the transmission process and other reasons caused by the actual download speed is not up to the theoretical speed. That you are 200kb/s words basically is 2M the actual speed broadband, if you connect broadband is 4M, then your actual download speed is basically in 400KB above irresolute back. Of course, 8M Broadband, you can calculate the theoretical download speed according to the 1024*8/8 calculation method.
