Answer:

Our simple assembler uses two major internal data structure; the Operation Code table (OPTAB) and the Symbol Table (SYMTAB). OPTAB is used to look up mnemonic operation codes and translate them to their machine language equivalents. SYMTAB is used to store values(addresses)assigned to labels.
