- This translation is done with the help of a translator program which is known as assembler.
- Assembler is a special program (translator) which translates symbolic operationcodes into machine codes, and symbolic address is addressed into an actual machine address.
- As shown in figure that the input to assembler is the assembly language program(source program) and the output is the machine language program (object program).
- Assembler translates each assembly language instruction into equivalent machine language instruction.
- There is one to one correspondence between the assembly language instructions of source program & the machine language instruction of its equivalent object program.
- In case of assembly language program the computer not only has to run the program but also must first run assembler program to translate the original assembly language program into machine language program.
- So the computer has to spend more time in getting desired answer.
