Radiation doesn't require the use of a medium- think of the Sun, for example, which heats us despite there being nothing directly connecting us. Convection requires a medium- when you put something less hot in something hot, the heat moves from the hot thing to the less hot thing.

Convection is the transfer of energy by movement of the medium present while radiation is transfer of energy through thermal radiation. Radiation does not require a medium.

Examples of Radiation are: Heat from the sun or feeling heat from a fire. A convection example could be boiling water: heat passes from the flame into a pot which heats the water at the bottom, then the hot water rises and cooler water moves down, resulting in a circular motion.
