Solution:

• An interpreter directly executes the source code of a program without the need for a separate compilation step. It reads each line of the source code, interprets it, and executes the corresponding machine-level instructions immediately.
• Unlike a compiler, which translates the entire source code into machine code or an intermediate code before execution, an interpreter processes the code line by line at runtime. This makes it easier to identify and correct errors since the interpreter can stop execution as soon as it encounters a mistake in the code.
• Interpreters are often used in scripting languages like Python, JavaScript, and Ruby, where the focus is on rapid development and ease of debugging.
