Compliler and Interpretor

We generally write a computer program using a high-level language. A high-level language is one that is understandable by us, humans. This is called source code.

However, a computer does not understand high-level language. It only understands the program written in 0's and 1's in binary, called the machine code.

To convert source code into machine code, we use either a compiler or an interpreter.

Both compilers and interpreters are used to convert a program written in a high-level language into machine code understood by computers. However, there are differences between how an interpreter and a compiler works.

Interpreter Vs Compiler

*Compiler= Translates program one statement at a time. Scans the entire program and translates it as a whole into machine code.

*Interpreters usually take less amount of time to analyze the source code. However, the overall execution time is comparatively slower than compilers. Compilers usually take a large amount of time to analyze the source code. However, the overall execution time is comparatively faster than interpreters.

*No intermediate object code is generated, hence are memory efficient. Generates intermediate object code which further requires linking, hence requires more memory.

*Programming languages like JavaScript, Python, Ruby use interpreters. Programming languages like C, C++, Java use compilers.
