As compared to a traditional cooktop where your gas stove is a separate unit, a hob is integrated into your kitchen countertop. Households with more members prefer having a hob with 4 burners, instead of a 2 burner hob. This comes in pretty handy when you have to cook multiple dishes or need to cook two things for a single meal. For example, you can boil rice on one burner, make rotis on the second burner, cook the sabzi on the third, and make tadka for the dal on the fourth.
