Top-down parsing attempts to find the left most derivation for a given string. Bottom-up parsing attempts to reduce the input string to first symbol of the grammar. Top-down parsing uses leftmost derivation.

WebTypically, compilers use top-down parsing. If you have left-recursion, then the parser goes into an infinite recursion. However, in right-recursion, the parser can see the prefix of the string that it has so far. Thus, it can check whether the derivation went "too far".
