The compiler produces an output program. The interpreter does not produce any output program. Therefore, the execution requires a source program every time. It is a two-step process as the program execution is segregated from the compilation. Execution begins only after the entire source-program is compiled. It is a one-step process because the execution process is part of the interpretation that is done line by line.
The compiler needs more memory to create an intermediate object code. The interpreter requires less memory because there is no such process of creating an intermediate object code. We cannot change or modify anything in the compiled program. To make changes, we have to change the source code. The interpreter uses the source code every time and works line by line; Therefore, we can easily make changes. The compiler displays all errors after compilation, which complicates the error detection and removal process.
The interpreter displays the errors of each line one by one, if any, making it easier to detect and remove errors. The compiler is best suited for the production environment. An interpreter is best suited for a software development environment. Summary Compiler and Interpreter both are intended to convert the source codes into machine codes, but there are differences in their working and operating procedure. However, there are differences between how an interpreter and a compiler works.

An interpreter is a computer program, which coverts each high-level program statement into the machine code.
This includes source code, pre-compiled code, and scripts. Both compiler and interpreters do the same job which is converting higher level programming language to machine code.
However, a compiler will convert the code into machine code create an exe before program run. Interpreters convert code into machine code when the program is run. It makes programming process easy. However, it must be translated into machine language before execution.
This translation process is either conducted by either a compiler or an interpreter. Also known as source code. Machine languages are very close to the hardware. Every computer has its machine language. A machine language programs are made up of series of binary pattern.
Machine language programs are executable so that they can be run directly. To make code portable, the source code is first converted to Object Code. It is an intermediary code similar to machine code that no processor will understand. At run time, the object code is converted to the machine code of the underlying platform. To exploit relative advantages of compilers are interpreters some programming languages like Java are both compiled and interpreted. The Java code itself is compiled into Object Code.
At run time, the JVM interprets the Object code into the machine code of the target computer.
