Machine code is the actual binary that makes up the program. object code is a compiled version of the source code

Question 2

What is the process of converting source code into machine code

Answer 2

Translation

Question 3

What is the difference between an interpreter and a compiler

Answer 3

An interpreter goes line by line while the program is being run. A compiler translates the entire program into object code before runtime

Question 4

Give an advantage of using a interpreted language

Answer 4

Easy to test source code because it does not need to be recompiled every time

Question 5

Give a disadvantage of an interpreter

Answer 5

Translation software is required at runtime
Code is not optimized
Speed of execution is slower
Source code is required

Question 6

Give an advantage of a compiler

Answer 6

Source code is kept private
Speed of execution is faster
Code is optimised
No need for translation at runtime

Question 7

Dive a disadvantage of a compiler

Answer 7

Program will not run with any syntax errors
Code need to be recompiled each time it is changed
Designed for a specific type of processor

Question 8

What is a procedural language

Answer 8
