Assembly language is known as a ‘low level language’. What does that mean?
• It is almost the same as machine code. There is a direct link between an instruction in assembly and the machine code it represents

Give one advantage for using assembly language?
• Programs run very fast compared to programs written in high level language, because there is less code overall

Types of programming languages
Give two features of a high level language
- It has a set of keywords such as PRINT or IF
* It has a set of grammar rules (syntax) which define how to combine the keywords correctly

High level languages are machine independent. What does this mean?
• They can be ported to different computers and still run

What is the purpose of a ‘compiler’?
• It converts high level source code into machine code
Types of programming languages
What is this?
• It converts high level source code into machine code
the purpose of a ‘compiler’
Types of programming languages
What file type will be created after using a compiler?
• .exe (executable) file
Types of programming languages
What is this?
• .exe (executable) file
the file type will be created after using a compiler
Types of programming languages
Give one benefit of using an executable file format
• It doesn’t require the complier or source code to be present to be run
Types of programming languages
What is the purpose of an ‘interpreter’?
• It converts a single line of high level source into machine code and then immediately runs it

Interpreters and Interpreted code
- Interpreters compile the source code line by line
- Interpreters don’t create an executable file
- Interpreters are required for the code to be run
- Interpreter code tends to run very slowly
