what is addressing mode? and what is the meaning of these following statements
BYTE_VALUE DB 150; A byte value is defined
WORD_VALUE DW 300; A word value is defined
ADD BYTE_VALUE,65;An immediate operand 65is added
MOV AX,45H
what is 45h?

It's not an address, it's just a hexidecimal value. We use base 16 in computers a lot because it makes thinking about numbers in terms of bits easier. 45h = 69

These commands are exactly identical as far as the computer is concerned.
MOV AX, 45H
MOV AX, 69
