Amateur radio, also known as ham radio, describes the use of radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation,radiosport, contesting, and emergency communication. The term "amateur" is used to specify "a duly authorised person interested in radioelectric practice with a purely personal aim and without pecunary interest;" (either direct monetary or other similar reward) and to differentiate it from commercial broadcasting , public safety (such as police and fire), or professional 2-way radii services (such as maritime, aviation, taxis, etc.).
Radio is the technology of using radio waves to carry information, such as sound, by systematically modulating properties of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width.When radio waves strike an electrical conductor , the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form.

Hey mate here is ur query...
**********************
Amateur radio is for two-way communications in specific frequency bands that are set aside for radio operators to experiment and practice using communications. They also perform emergency communications during weather or other emergencies. HAM radio operators must be licensed by taking a series of tests for varying privileges. (Morse code is no longer required in the US.)
"Common" radio could be referring to broadcast stations (am/fm on your radio dial) that are commercial or non-profit methods of one-way communication.
"Common" could also mean systems like GMRS, FRS or business bands that are licensed for a fee by the FCC (in the US). No one is authorized to use these bands without the proper licensing (CBs and FRS do not require licenses). Some of the commercial licenses require testing, but they generally charge higher fees than the HAM licenses.
