The CMBR is microwave radiation coming to our Earth with the same intensity (to within one part in 100,000) from all parts of the sky. Its spectrum is exactly that of a black-body -- ie, like that of a glowing object -- at a temperature 2.7 degrees above absolute zero.
It is believed to be the remnant of recombination, 377,000 years after the Big Bang. No other hypothesis about our Universe can explain the CMBR other than saying, "It's just there and I don't know why it should be."

The radiation left over from the big bang is found in the microwave region of the electromagnetic spectrum. As the universe expanded and cooled, the intense hard gamma radiation that existed became radio waves in the low gigahertz region, characteristic of a temperature around 30 Kelvin.

CMB is cosmic microwave background radiation. It is the radiation that is the basis for the Big Bang theory.

In the 1960s, microwave radiation was detected coming from space and no particular source, and this radiation was dubbed the Cosmic Microwave Background Radiation (CMBR).
