Difference Between Kbps And KBPs

Lots of people have confusion between Kbps and KBps ,,,, Even he/she know the that Kbps means "Kilo bits per seconds" as a transfer rate.

KBps means "Kilo Bytes per second" as a transfer rate. even they are confused when they saw or listen 1mbps or 50 KBps because all data card or network provider mentions KBps or Mbps. so there's a lot difference between Kbps and KBps as i mentioned above .... :P
so

8 bits = 1 byte
256 kbps = 32 KBps
512 kbps = 64 KBps
1 mbps = 128 KBps
2 mbps = 256 KBps
now don't waste your time on calculating :P
