'db' is the pseudo-operation code for define byte. Most assemblers will take a comma separated list and assemble that many bytes into memory.
Similarly 'dw' is for define word and there may be others that assemble lonmger blocks of constant data including 'ascii' and 'asciz' which are strings with and without null terminators.
