Conduction moves heat through a solid by adjacent molecules transferring their vibrations. The molecules' mean positions in the solid remain fixed. Conduction can occur in a fluid (liquid or gas) also, but it is only by transfer of vibrational energy, molecule to molecule. Convection moves heat through a fluid by bulk movement of the hot vibrating molecules.

Conduction occurs when heat transfers through a material, like metal. The flame on a stove heats the pan, and the heat conducts through the metal to the food. Convection carries heat through a medium, like air or water. Air moving through a furnace plenum convects the heat from the heat exhanger through a house to warm you.

Heat conduction is the transmission of heat across matter.
Convection is the internal movement of currents within fluids (i.e. liquids and gases). It cannot occur in solids due to the particles not being able to flow freely.
