What is the difference between a compiler and an interpreter?

In order for a program written in an advanced language to be performed on a computer, it must be replaced with a language that the computer can understand directly. Programs that do this are called compilers. The translation process is cumbersome and takes a long time because it has to go through the translation and execution process, but the translation speed is fast because it does not translate again once it has been translated.

Unlike a compiler that converts a source program into machine language at once, it is a 'language processing program' that interprets and executes the program step by step in machine language. It is useful for time-sharing systems because it is translated and executed on a line-by-line basis, and responds quickly to changes in raw programs. It is suitable for interactive languages that are being tested and modified step by step, but it has the disadvantage of being slow due to its long execution time. Because the program runs directly, no target program is created.
