It contains words and phrases from the English (or other) language. But a computer does not understand high-level language. It only understands program written in 0's and 1's in binary, called the machine code. A program written in high-level language is called a source code. We need to convert the source code into machine code and this is accomplished by compilers and interpreters. Hence, a compiler or an interpreter is a program that converts program written in high-level language into machine code understood by the computer.  Interpreter :      1. Translates program one statement at a time.      2. It takes less amount of time to analyze the source code but the overall execution time is slower.      3. No intermediate object code is generated, hence are memory efficient.  ...
