T4.3.5 Computational Thinking

High-level languages

• Human-readable languages translated to machine code.
• Languages readable by computers, translated to binary.
• Program after translation to machine language.

Translation method

• Conversion of high-level code to machine-readable instructions.
• Changing low-level code to human-readable instructions.
• Changing machine code to source code.

Source program / source code

• Program before translation to machine language.
• Translated code ready for machine execution.
• Code translated but not yet ready for execution.

Object program / target program

• Translated code ready for machine execution.
• Code translated but not yet ready for execution.
• Program after translation to machine language.

Compilation

• Compiler converts source to machine code.
• Compiler changes machine code to source.
• Compilar executes code all at once.

Interpreter

• Interpreter executes code line-by-line.
• Interpreter executes code all at once.
• Interpreter translates code into binary.

Compiler

• Software translating entire code to machine language.
• Program translating code to pseudocode
• Compiler executes code all at once.

Syntax errors

• Errors hindering compilation or interpretation.
• Errors related to the incorrect use of grammar in the code
• Errors related to the incorrect use of comments in the code

Compilation process

• Steps converting source to executable code.
• Steps converting source to high-level language code.
• Reading code line-by-line, correcting errors.

Interpretation process

• Reading code line-by-line, correcting errors.
• Reading code but without correcting errors.
• Steps converting source to executable code.
