Assembly language refers to a low-level programming language that needs an assembler for converting the instructions to machine or object codes. Ease of comprehension Machine language cannot be deciphered by humans and can be comprehended only by computers.

Assembly language can be understood, used, and applied by humans. Nature of syntax Machine languages comprise of binary digits 0s and 1s.

Assembly languages have a syntax that is similar to the English language; therefore, they can be understood by programmers and users alike. Dependency Machine languages are platform-dependent, and their features vary accordingly. Assembly language comprises of standard instruction sets. Areas of application Machine language serves as a machine code only. Usage of mnemonics Machine language uses sequences of bits for giving commands.

One depicts the true or on the state; on the other hand, zero depicts the false or off state. The conversion of high-level programming language to machine language is dependent on the CPU. Assembly language does not require users to remember op-codes.

The codes in assembly languages are slightly more readable and can be mapped to machine code by humans. Generation of programming language Machine languages are first-generation programming languages.

Assembly languages are second-generation programming languages. Modification Machine language does not support any change. Execution is fast in machine language because all data is already present in binary format. Execution is slow as compared to machine language. There is no need of translator. The machine understandable form is the machine language.

Assembler is used as translator to convert mnemonics into machine understandable form. Machine language is hardware dependent. Assembly language is the machine dependent and it is not portable. Recommended Articles. Article Contributed By :.
