Unit of data rate of communications network and the like.Bitper second. 1bps displays the fact that the dataof 1 bit can be transferred to 1 seconds. 1kbps (1 kilometer bps) 1000bps and 1Mbps (1 Mega bps) 1000kbps (100 ten thousand bps) is.

1kbps 1024bps and 1Mbps are designated as 1024kbps when and, when you write with "k" and the Kohumi letter, when 1000 times, you write in "K" and capital letter, 1024 times, and so on with there is also a theory which is done, confusion state is continued centering on these uses.

Originally, with the SI system of units which is used asuniversal system of units as for "k" and "M" and so on prefix meaning we have the meaning of involution of 1000,followthese uses formally even in the academic society standardization group and the like of IEEE and IEC etc.. But,dawn of the computerfromcircumstancesin regard to the design of the software and the hardware, fromthe fact that 1024 bitsare designated as the 1k bit, the person who applies this rule at such as capacity and transmission speed of the data increases, a confusion state the present way was caused. ... The continuation is read

In the world of communication, before data communication starts from,followingto SI system of units, we use 1000 times, in addition,the transmission speed of modem at the beginning like 75bps, 300bps and 1200bps etc. is thought that it is applied to make 1kbps=1000bps, involution of 2 partly due to the fact that it starts from unrelated value. Speaking roughly,amongmemory capacityof memory and the hard disk etc. "1024", among transmission speed "1000" being used is many, but because there are times when it differs depending upon circumstance, whether you use in either sense sufficient note is necessary.

By the way, full speed of analog modem 56kbps (the descent. As for rising 33.6kbps),as forthe full speed of ISDN as for thefull speedof Ethernet LANof 128kbps and 100BASE-TX it is 100Mbps.
