Assembler is a prgorammer for converting instructions written in low-level assembly code into relocatable machine code and generating along information for the loader. It generates instructions by evaluating the mnemonics symbols in operation field and find the value of symbol and literals to produce machine code.

When a name appears a second time in the source-program, it is replaced with its assebmler from the table. The object-program must be loaded into the memory of the explain first pass of assembler programmer before it is executed.
For this, a Loader Program is used.
