Compilers and Intepretors Characteristics:

Question 1

What is a compiler?

Answer 1

= Translates source code into object code and then machine code to be executed by the CPU.
= Whole programme is translated into machine code before running.

Question 2

What are the advantages of a compiler?

Answer 2

= Execution speed is faster.
= Code is usually optimised.
= Original source code is kept secret.

Question 3

What are the disadvantages of a compiler?

Answer 3

= Programme will not run with syntax errors= makes it difficult to write the code.
= Code needs to be recompiled when code is changed.
= Designed for a specific type of processor.

Question 4

What is an intepreter?

Answer 4

= Translates source code into machine code ready to be processed by the CPU.
= Translated line by line when the programme is running.

Question 5

What are the advantages of a intepreter?

Answer 5

= Stops when finding a syntax error.
= Does not need to be recompiled when code is changed.
= Easier for begginner coders.

Question 6

What are the disadvantages of a intepreter?

Answer 6

= TRanslation software is needed at run time.
= Speed of exeuction is slower.
= Code is not opttimised.
= Source code is needed.
