Compilers and interpreters

• It is a translator which takes input i.e., High Level Language and produces an output of low level language i.e. machine or assembly language.

• Compiler is more intelligent than an assembler it checks all kinds of limits, ranges, errors etc.
• But it’s program run time is more and occupies a larger part of memory. It has slow speed because a compiler goes through the entire program and then translates the entire program into machine codes.

Interpreter:

• An interpreter is a program which translates a programming language into a comprehensible language.
• It translates only one statement of the program at a time.
• Interpreters, more often than not are smaller than compilers.
