definition of assembler structure, Basic Computer Science

Assignment Help:
In assembly language code lines have two fractions, the earliest one is the name of the instruction which is to be executed, and the next one are the parameters of the command. For example: add ah bh
Now "add" is the command to be executed, in this condition an addition, and "ah" as well as "bh" are the parameters.
For instance: mov al, 25
In the above instance, we are using the instruction mov, it means for moving the value 25 to al register.
To make the name of the instructions in this language two, three or four letters are used generally. These instructions are also known as mnemonic names or operation codes, given that they represent a function the processor will perform.
Sometimes instructions are used as follows:
Add al, [170]
The brackets in the second parameter show to us that we are going to exertion with the content of the memory cell number 170 and not with the 170 value; this is identified as direct addressing.
