Because the iodine is liberated, hence it is called as iodometric titration.
hypo solution used in iodometric titration is sodiumthiosulphate. Its N\10 normality of Na2S2O3.
excess KI
No, they are not the same, but 1 is part of 2.Iodometric titration is just one of the (larger) group (or class) of oxidimetric titrations, which in turn is part of the much (larger) group (or class) of volumetric analysis method.

drift means gram eqv. of water removed by K.F. in Iodometric titration
It is used as indicator for the endpoint of a Iodometric (redox) titration: it gives a bluish grey to black color with very minute excess of Iodine-iodide ions (I3-)
indicates end of titration neutralisation of the reaction
change in pH, changes the colour (of the indicator)
titration
Iodometric titration is synonymous with redox titration method. Iodine is a universal laboratory reagent because it reacts directly with an array of organic and inorganic substances. Since iodometric titration is a form of redox or oxidation-reduction reaction, it can accurately measure the amount of oxidizing or reducing agents in a chemical reaction. Also, it can be reversed to either direction in an iodine/iodide reaction.
The color formed by reaction between starch and iodine is much more intense than the color of iodine itself, so that the end point can be determined more sensitively with than without starch.
