The main difference between compiler, interpreter and assembler is that the compiler converts all high-level language programs to machine language at a time while the interpreter converts high-level language programs to machine language line by line and assembler converts assembly language programs to machine language.
A computer program is a set of instructions for a computer to perform certain tasks. Most programs are written in high-level or assembly language. These programs are easy to read and understand by programmers but not by computers.
Computers only understand machine language. It consists of binary ones and zeros. Therefore, high-level programming or assembly must be changed to machine language so that the computer understands the instructions. Compilers, interpreters and assemblers are translators that convert high-level language-based programs or assemblies into machine language.
Definition of Compiler
Compilers are language translators that convert high-level programs into machine code that can be understood by machines. In this process, the compiler converts the entire program into machine code at a time. If there is a syntax or semantic error, the compiler will show it. It checks the entire program and displays all errors. It is impossible to execute a program without fixing the error.
Programming languages like C, C ++ use compilers for language conversion. The implementation time is lower in this language. Because of this, they are considered fast language.
Definition of Interpreter
Interpreters are also language translators who convert high-level programs into machine code. Unlike compilers, interpreters convert source code to machine code line by line. Because it checks line by line, the scan time is lower. But the overall execution time is higher.
The interpreter displays an error at a time. The programmer must correct that error to interpret the next line. Programming languages like Python, Ruby, PHP, Perl are some examples of translator-based languages.
Apart from high-level languages and machine languages, there is another language called assembly language. Assembly language exists between high-level languages and machine languages. This is closer to machine language than high-level language. This is also called low-level language. This language is not easy to read and understand by programmers like high-level programming languages. Assembler works as a translator in turning assembly language programs into machine code.
Difference Between Compiler, Interpreter, and Assembler
Compiler: Compiler is software that converts programs written in high-level languages to machine languages.
Interpreter: Interpreter is software that translates high-level language programs into machine language.
Assembler: Assembler is a software that converts programs written in assembly language to machine language.
Compiler: Compiler converts all high-level language programs to machine language at a time.
Interpreter: The interpreter changes high-level language programs to machine language line by line.
Assembler: Assembler converts assembly language programs into machine language.
Compiler: Languages like C, C ++ use compilers to convert code.
Interpreters: Languages like Ruby, Perl, Python, PHP use Interpreter.
Assembler: Assembly language uses assembler.
Compiler, Interpreter and Assembler are language translators. The difference between the compiler interpreter and assembler is that the compiler converts all high-level language programs to machine language at a time while the interpreter converts high-level language programs to machine language line by line and the assembler converts assembly language programs to machine language.
