i) Absolute Reference: It is the cell address in the formula that is fixed. They do not change if you copy a formula from one cell to another. It is given by preceding both column and row number by the dollar sign($). Example- Formula =$A$1*B1,   If it is copied down a column it will change to =$A$1*B2

ii) Relative Reference: It automatically changes when the formula is copied to a new location. The changed cell address will be relative to the address of the cell containing formula. Example the formula =A1*B1 is copied down a column it will change to =A2*B2
