TRANSLATIONS/IDE

Question 1

LOW LEVEL CODE - ADVANTAGES

Answer 1

• uses less memory.
• can run faster.
• can manipulate hardware components directly.

Question 2

LOW LEVEL CODE - DISADVANTAGES

Answer 2

• harder to learn
• hard to find errors within the code/debug
• specific to one machine.

Question 3

HIGH LEVEL CODE - ADVANTAGES

Answer 3

• easy to learn and understand
• easier to find errors/debug
• more portable to different machines

Question 4

HIGH LEVEL CODE - DISADVANTAGES

Answer 4

• will run slower

- takes more memory and slower to run

Question 5

WHATS A COMPILER, WHAT DOES IT DO, AND WHAT ARE ITS ADVANTAGES/DISADVANTAGES (COMPARED TO INTERPRETERS)

Answer 5

it converts the whole code into an object code (an executable version of the program) before running it. The object runs independently from the source code and compiler. used in distribution.

Advantages:

• customers cannot see the source code when you distribute the program.
• code runs quickly when compiled.

Disadvantages:

• slow to compile.
• can be more difficult to debug as errors are generated at once for all the code.

Question 6

WHATS AN INTERPRETER, WHAT DOES IT DO, AND WHAT ARE ITS ADVANTAGES/DISADVANTAGES (COMPARED TO COMPILERS)

Answer 6

it converts the code one instruction at a time, and executes the instruction before moving to the next. it does not create object code and the source code is ran each time. Mainly used in development.

Advantages:

• Easy to debug code.
• Code can be developed and tested in stages.

Disadvantages:

• Interpreter is needed on the target machine.
• Slower run time because the program is translated every time it is run.

Question 7

DEFINITIONS

Answer 7

• [Object code] A translated version of the program (source code) that can be run without the source code.
• [IDE] Integrated Development Environment Features.
• [Editor] An editor which allows you to enter and edit the code. This can have features to make it easier to write your code by using colour coding and automatically indenting your code.
• [Run time environment] Allows the code to be run as its being developed.
• [Translator] May have a compiler or interpreter or both to translate the high level code to machine code.
• [Error diagnostics] These identify errors in code and potential problems.
