Parboiled Rice - This “rough” rice has gone through a steam-pressure process before milling that gelatinizes the starch in the grain. This process produces a more separate grain that is light and fluffy when cooked. Converted rice is a type of parboiled rice that has been further pre-cooked, which ultimately allows you to whip up dishes of rice even faster.
Samba is a variety of rice grown in Tamil Nadu, some other parts of India and Sri Lanka, and has a small ovular grain, compared to the long grain of basmati rice. This rice is also very popular in West Bengal and there it is known as Gobindo bhog.
