2. Lesson 1

3. Classification of languages
Low-level
Written to control the processor directly.
Machine code - binary
Assembly language - mnemonics
All programming languages/instruction have to translated into machine, this happens in various ways (discussed later).

4. Classification of languages
High-level
Invented for the convenience of human beings, looks more real languages and each one is designed to tackle a range of problems.

5. Classification of languages

To be discussed and reviewed with the class once the allocated time is up.

7. 2.5 Translators & Types of Languages
What features should the next generation of programming language have?
How does the programmer of the future envisage programming and therefore how should programming languages now be designed?
What would be the benefits of programming in a new generation?

8. Lesson 2

9. Assembly Language
Often used in embedded systems because it has the following features:
Complete control over the hardware allowing easy manipulation of individual components
Code can be short and specific to machine which saves memory space.

10. Translating programs into machine code
All programming languages/instruction have to translated into machine, this happens in various ways (discussed now).
Uses something called a translator.
Assemblers
Compiler
Interpreter

11. Student Task ( slide ##)
Comparison
Compiler

Description of assemblers:
Explanation of compiler:
Translating programs into machine code
Explanation of interpreter:
To be discussed and reviewed with the class once the allocated time is up.
Question the group about difference between the three of them.
