Assembler, Compiler and Interpreter Information Technology Essay ||| Assembler, Compiler and Interpreter Information Technology Essay ||| Difference Between Compiler and Interpreter Difference Between Compiler and Interpreter. Programmers generally write computer programs using high-level languages. High level. The main distinction between a compiler and an assembler lies in their functionality. A compiler is designed to translate high-level programming language code into machine language code. Conversely, an assembler is responsible for translating assembly-level language code into machine language code. Both compiler and Compiler Alternative: the interpreter. Another core tool for executing source code is called an interpreter. An interpreter executes the source code line by line, without compiling it into machine code. Because of the line-by-line interpretation, an interpreted program typically runs slower than compiled code. The assembler enters the arena after the compiler has played its role. The assembler translates our assembly code into the machine code and then stores the result in an object file. This file, Interpreter, only looks at one line of program at a time. Compiler is faster. Because the interpreter translates line by line, the interpreted code executes more slowly than the compiled code. Takes longer to compile, but super fast execution. Immediate response, but execution slowly. Errors are reported during the compilation process.
