It is the only language which a computer understands without using a translation program.

Machine Language, Assembly and High level computer Language

Machine language is the low level programming language. Machine language can only be represented by 0s and 1s. In earlier when we have to create a picture or show data on the screen of the computer then it is very difficult to draw using only binary digits 0s and 1s.

For example: To write in the computer system its representation is So it is very difficult to learn. To overcome this problem the assembly language is invented. Assembly language is the more than low level and less than high-level language so it is intermediary language. Assembly languages use numbers, symbols, and abbreviations instead of 0s and 1s. For example: For addition, subtraction and multiplications it uses symbols likes Add, sub and Mul, etc. Writing code in comment?

Assembly language is only understand by human beings not by the computers. In machine language data only represented with the help of binary format 0s and 1s , hexadecimal and octadecimal. In assembly language data can be represented with the help of mnemonics such as Mov, Add, Sub, End etc. Machine language is very difficult to understand by the human beings.

Assembly language is easy to understand by the human being as compare to machine language. Modifications and error fixing cannot be done in machine language. Modifications and error fixing can be done in assembly language. Machine language is very difficult to memorize so it is not possible to learn the machine language.

Easy to memorize the assembly language because some alphabets and mnemonics are used. 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.

A programming language - Is a formal language, which comprises a set of instructions that produce various kinds of output. Programming languages are used in computer programming to implement specific algorithms. Most programming languages consist of instructions for computers.


The binary code is called the machine code or machine language. The exact machine language for a program or action can differ by operating system on the computer. Computer programs are written in one or more programming languages, like C++, Java, or Visual Basic.


3.2.9 Classification of Programming Languages

A low-level programming language is a programming language that provides little or no abstraction from a computer's instruction set architecture —commands or functions in the language map closely to processor instructions. Generally, this refers to either machine code or assembly language. Because of the low hence the word abstraction between the language and machine language, low-level languages are sometimes described as being "close to the hardware". Programs written in low-level languages tend to be relatively non-portable , due to being optimized for a certain type of system architecture.
