It is an ordered tree in which nodes are labeled with the left-hand sides of the productions, and the children of the nodes represent the corresponding productions’ right-hand sides.

WebDerivation is a sequence of production rules. It is used to get the input string through these production rules. During parsing, we have to take two decisions. These are as follows: We have to decide the non-terminal which is to be replaced. We have to decide the production rule by which the non-terminal will be replaced.
