burning a cd


I am trying to make a copy of a cd that has a program on it.Its not a copy righted program so I should be able to burn it.I'm new to mac but in windows I would open a burn program and choose the disc and it would burn on a cd.I dont know what program to use to do this with mac.I have idvd and dvd player but this a cd and a program not music or video.I would also like to know how to make a copy of my imac install disc for a backup if its possible.
