Lesson 15 - IDEs
Compilers
Compilers
- Translate entire source code all in one go into Machine Code
- Optimise code
- Used at the end of development (ready for shipping)
- Error Reports created along with Object Code
Interpreters
- Translate and execute source code
- Line by Line, Statement by Statement
- Source code is checked for syntax – if correct, code is executed. If incorrect interpreting is stopped.
- Used for development (aide debugging)
Answers
Assemblers
- Translate Assembly Language code into Machine Code
- Used for Device Drivers
- Used when fast execution is required or limited memory/file size
- Difficult to write in (easier than Machine code)
Lesson Objectives
To be able to describe how an Assembler works
To be able to describe the differences in operation between a Compiler and Interpreter
To be able to describe the common tools and facilities in an Integrated Development Environment (IDE)
Revise, Recap, Review
3 types of comparison operators and their function
2 logic gate diagrams (labeled)
1 explanation of the difference between machine code and low level programming languages
Lesson 15 - IDE's
Assembler, interpreter or compiler?
Translators
Assembler for 2nd GEN - ASSEMBLY LANGUAGE
Interpreters or compilers for 3rd GEN
To use ANY kind of programming language we must first translate it into a code that the computer can understand
Task
You will be handed either a sheet on Compilers or Interpreters:
- Spend 10-15 minutes completing the task given on the sheet to produce a diagrammatic form of the text (e.g. MindMap, Cartoon etc).
- Work with a partner to explain to them what is meant by Compiler/Interpreter using only your notes.
- Check understanding (peer assess each other)
What is the name of this code?

IDE's
An IDE is an Integrated Development Environment
They consist of:
An editor
Error diagnostics
Run-Time diagnostics
Translator
