although technically they both mean the same thing, saying "Do not" adds a little more emphasis.

they are absolutely the same, only that the latter sentence used contraction (i.e. a word formed from two or more words by omitting or combining some sounds). do not = don't In formal writing or speech, the former sentence is preferred. :)

i think they are not the same becoz the first one is more threatning than the other .but both of them are correct only difference in meaning.thats what i think

It's the same, you can use them both. ''don't'' is just short for ''do not''. But I think ''don't'' is used more often, and I never say ''do not''.

they are both the same.. don't is the short "contraction" form of do not.
