Difference between Assembly and Machine Language

Programming languages are combination of well-defined instructions used for computers. There are two types of programming language Assembly Language and Machine Language. The programming language was developed in 1950s. The program guides the computer to precede any tasks. The grammatical rules followed in programming language are called syntax. High level language is easily understood by human while low language is difficult to understand.

Assembly Language

It was developed in 1940s. Before the invention of Assembly language the computer code were written in 0s and 1s which is difficult for human to understand. Second generation language is known as Assemble Language. Assemble Language is converted into machine code by using an assembler.

Machine Language

Machine Language is in the form of 0s and 1s. This language is not easily understandable by the human but this is the real language of computer which the computer understands in the form of bytes. It is first generation language. And it is much difficult than Assembly Language and more time is required for understanding this language.

Assembly Language VS Machine Language

Readability:

The readability of Assembly Language is very high as it is written in English which is understandable by human beings.

The readability of Machine Language is less as compared to Assembly Language because it is written in the form of binary code which normal human being cannot understand. But this is the actual language of computer.

Platform Dependency:

The Assembly Language is platform dependent and so at the present time most programs are written in third generation language.

Machine Language varies from platform. Different platform have different machine language code.

Modifiable:

 It is necessary for survival of software to evolve.  So in order to avail this advantage the language should be easily modifiable. And Assembly Language is easily Modifiable and its support changes.

Machine Language cannot be changes easily and it does not support modification.

Quality:

The risk of occurrence of error is reduced in Assembly Language.

The risk of existence of error is high in Machine Language.

Memorability:

Memorability is high in Assembly Language because it is easy to remember variable name instead of binary code.

The binary code cannot be memorized.

Need of Compiler:

In case of Assembly Language interpreter is needed which is knows as assembler in case of Assembly Language to convert its code into machine code in the form of bits and bytes.

In case of Machine Language there is no need of compiler or interpreter because it is mother language of computer. So computer does not need any interpreter to understand its own language.

Conclusion

Assembly Language is preferred over Machine Language. There are many factors which make Assembly Language a remarkable language which are stated as the readability of Assembly Language is very much high than Machine Language. Changes can easily be made in Assembly Language in comparison with Machine Language. The risk of errors finding is reduced in Assembly Language than in Machine Language.
