Advantages of Assembly Language

The assembly level languages were made to instruct the machine. The assembler acts as the translator between the assembly language and the machine language. The assembly language can represent the machine language with mnemonics but these mnemonics are not understood by the machine therefore the assembler converts assembly language to machine language.


Use of mnemonic in assembly language

The machine language is quite difficult and computer scientists used to give instructions to computers in the form of ones and zeros in the first generation of computers. The assembly language was introduced in the second generation of computer onwards and made instructions giving process quite easier, if we had to add two-variable we can simply use ADD command in assembly language, but in machine language which was in the form of ones and zeros who have to write the exact code i.e. ‘1001’ along with digits in binary format to add.


Decreases the chance for programming errors

For the above reason, only the chances of human error also increase and when the error occurred it was nearly impossible to trace back from where it has originated but in assembly language, there were set of commands that the programmer has to remember such as addition, multiplication, division, modulus, subtraction, etc. with remembering only these commands the programmer can do the programs. Therefore assembly language reduced the chances for error.


Easier to debug

If you compare the assembly language to machine language you will find the assembly language to be easier for debugging process or removing the error from the code. With the use of the mnemonics, we can easily feature out which part of the assembly code is facing the error as they use the keyword which is alphanumeric and hence easier to catch with eyes than the machine language which is in zeros and ones the debugging can taking a great amount of time.


Assembly language is faster than any HLL

The assembly language is faster and efficient than any high-level language. First of all the assembly level language programmers are more skilled than high-level language programmers as it is much difficult to write code in assembly language which can give you errors in each line if you miss any operand. Second, assembly language does not have to be compiled and interpreted as most languages such as JAVA which slows down the program up to 10-20 times, and also the wrong way of writing algorithm and data structure can further slow down a program 100 times. The assembly language does not support such unnecessary features that can slow down the program as the compiler and interpreter do in the high-level language 


The assembly language uses hardware resources more effectively

The assembly language is closer to the hardware than any high-level language. The assembly language tends to be more focused on writing code for the hardware whereas the high-level languages are more focused on writing code for the software. The property for the assembly language to be writing codes for hardware leads to writing better codes as assembly language can utilize the hardware resources such as register, memory, cache, etc in a more efficient manner which a high-level language never does.
