KBPS

Kbps means "thousands of bits per second".  The K of course implies that the number would be in the thousands.  "Bits per second", bps, refers to the speed at which data can be sent.  The higher the "bps" the more data that can be sent rapidly.  So 25 Kbps then would mean a data rate of 25,000 bits per second.  Note that there is also a term of Mbps that can refer to millions of bits per second that can be transmitted.

For example, some phone lines using a standard modem may transmit at 28 Kbps.  While that is seen as an acceptable data speed for some, web pages may load slowly at that data rate, and so many consumers switch from standard telephone modems to DSL or high speed cable internet to speed up their internet experience.

In general, the higher the bps, or Kbps, or Mbps, the more data that can be sent rapidly.  So, "more" is often better in this case.
