In India, curd is marketed as "yoghurt."
see http://en.wikipedia.org/wiki/Curd
Curd and Yoghurt are indeed used interchangeably in many parts of (mostly urban) India and the region in general, though probably not in the UK, the US and some other parts of the world. (Thanks to @Peter Shor for the guidelines).
This answer seems to do a good job of explaining the difference. Yogurt and curd are similar in that bacteria are used to produce lactic acid to thicken the milk. They're different in that yogurt is made with pure culture for consistency.
They are totally different things. I am a Turk and both products are highly consumed in Türkiye. We call curd lor in Turkish, and it is very similar to cheese:
On the other hand, yoghurt is a different product.
Both are made of milk.
Coming to the rescue of all those confused Indians. In India, yoghurt is 'dahi' . Most Indians are confused because in India,the commercial name of yoghurt is 'curd' at most places. http://en.wikipedia.org/wiki/Yogurt.
'Meetha dahi' is flavoured(sweetened) yoghurt.
Outside India, what is recognised as curd is the preprocessed form of 'paneer',i.e., paneer after the excess water(or whey,as the rest of the world recognises it)is drained out and before the paneer hardens. This is called curd outside India.
http://en.wikipedia.org/wiki/Curd - curd
For all those non-Indians, 'paneer' is a form of cottage cheese made in India. For the a detailed difference between yoghurt and curd, follow the links provided.
In American English,
is a milk-based food that is cultured with yoghurt-specific bacteria, is a soft and smooth, ranging from jello-like to almost pourable consistency served in a tub, usually eaten at breakfast time. It is usually mixed or served with fruit. There are hundred's of commercially available varieties.
all by itself is rare in AmE except in technical circumstances. For the food 'cottage cheese', where milk has formed into 'curds', small lumps of congealed milk solids, by chemical processes (not bacterial ones). Cottage cheese is often labeled 'large curd' or 'small curd' (depending on the size of the gobbets of coagulated milk).
One would never mistake 'yoghurt' for 'curd' because yoghurt creamy smooth and sweet/sour, and 'curd' is a technical descriptor for a congealed bit of milk solids an sounds weird as singular. 'Curds' are what you might describe cottage cheese, and are lumpy bits, tasting cheesy.
Curd is a more generic word than yoghurt - and curd is not always made from milk. For example, you can also get lemon curd and bean curd. Curd can simply mean a liquid that has "curdled". Yoghurt on the other hand is more specific in definition.
The question starts with two statements:
Most people use the words curd and yogurt interchangeably.
Both are made by fermenting milk.
Neither of these are necessarily true. The first answer refers to a wikipedia article which states the same thing and has a reference link back to this page. Which means the statement has no real reference (just an echo).
But onto the question:
Is there a difference between the two, or are they the same?
Yogurt/Yoghurt is indeed fermented with a specific pair of bacteria, but curd is not, rather it is coagulated/curdled milk. Many things can cause curdling (including adding citric acid) but yogurt fermentation is the action of very specific bacteria that transform lactose into lactase.
In India curd and yogurt are the same: "curd" is called plain yogurt and if we add something to it, like fruit, it becomes fruit yogurt.
In India, curd is often used when it is prepared domestically. When produced on a large scale and packed, it is termed yoghurt.
Both Curd and Yoghurt are made from milk by fermentation. If it is plain it is curd and if more sugar added it is called yoghurt.
