What are Compiler and Interpreter? Linking-Loading Method and Interpretation method.

Hello, my name is Kishan Tongrao. Today we are going into another basic concept.

What is Compiler?

• A compiler is a program that is only responsible for carrying out a translation, not the program execution.
• Here all program statements or expressions are compiled(It is the process of creating an executable program).
• Due to the above statement, the compiler is faster than the interpreter.
• It follows the Linking-Loading method.

What is Linking-Loading method?

• Loading – The process of bringing the program from secondary memory to primary memory.
• Linking – The process of establishing the connections between all the modules or functions of the program so that the complete program can run properly is called Linking.

What is Interpreter?

• An Interpreter is designed to both translate and execute.
• Here each line of code is converted into machine code.
• Due to the above statement, the Interpreter is slower than Compiler.
• It follows the Interpretation method.

What is Interpretation method?

• Here each line is passed to the interpreter. Where the line gets compiled and ready for execution.

Enjoy !
