Microwaves are electromagnetic radiation in the radio portion of the spectrum. The can be used like radio to send data; they are used in radar to bounce back of objects; they are used in microwave cookers to heat food.
The carrier is the actual EM energy used for transmission. The band is a subset of a convenient (and arbitrary) human conception of the electromagnetic spectrum. It's analogous to a real pencil line (the carrier) drawn in an imaginary lane (the band) of an endless expanse of very real concrete (the electromagnetic spectrum).
