GCSE AQA 04 Computer Systems - Languages & Translators

Programing languages designed to make it easier for humans to understand and write computer programs, than using low-level languages. Examples include Python and C#.

• High-Level Language
• Easy
• Fast
• Interpreter
• Translator

Programming languages which are a much closer representation to the instruction set of the processor. These include assembly language and machine code.

• Low-Level Language
• High-Level Language
• Easy
• Fast
• Interpreter

Computer programs written in a high-level language, the computer cannot execute these

• Source Code
• Low-Level Language
• High-Level Language
• Easy
• Fast

A low-level language which uses mnemonics such as LDA, ADD to represent machine code instructions

• Assembly Language
• Source Code
• Low-Level Language
• High-Level Language
• Easy

A low-level language which the CPU can process directly, and consists of only binary codes which are very hard to write directly, to change and to debug

• Machine Code
• Assembly Language
• Source Code
• Low-Level Language
• High-Level Language

A short abbreviation used in assembly language to represent a machine code instruction, such as STA, SUB, JMP

• Mnemonic
• Machine Code
• Assembly Language
• Source Code
• Low-Level Language

A type of translator which converts a high-level language in to machine code all at once

• Compiler
• Mnemonic
• Machine Code
• Assembly Language
• Source Code

A type of translator which translates assembly language in to machine code

• Assembler
• Compiler
• Mnemonic
• Machine Code
• Assembly Language

A program which converts source code into code which the processor can execute, this can be a compiler, interpreter or assembler

• Translator
• Assembler
• Compiler
• Mnemonic
• Machine Code

This translator converts a high-level language into machine code one line at a time and then executes it, it's slower but interpreted code is quicker to write and easier to update

• Interpreter
• Translator
• Assembler
• Compiler
• Mnemonic
