What is the difference?

A compiler is a computer program (or set of programs) that translates text written in a computer language (the source language) into another computer language (the target language). The original sequence is usually called the source code and the output called object code. Commonly the output has a form suitable for processing by other programs (e.g., a linker), but it may be a human readable text file. Assembler may refer to:Assembler for an assembly language, a computer program to translate between lower-level representations of computer programs. Interpreter (computing), a program designed to run other non-executable programs directly. Hope this helps.

I do not imagine minimally how many lines are
