Programming languages and translators
Cambridge IGCSE Computer Science (0478) · Unit 4: Software · 9 flashcards
Programming languages and translators is topic 4.3 in the Cambridge IGCSE Computer Science (0478) syllabus , positioned in Unit 4 — Software , alongside Types of software and Operating systems. In one line: A high-level language uses English-like statements, making it easier for humans to read and write. Advantage: Programs are easier to debug and maintain compared to low-level languages.
This topic is examined in Paper 1 (computer systems theory) and Paper 2 (algorithms, programming and logic).
The deck below contains 9 flashcards — 8 definitions and 1 application card — covering the precise wording mark schemes reward. Use the 8 definition cards to lock down command-word answers (define, state), then move on to the concept and application cards to handle explain, describe and compare questions.
'high-level language' and provide an advantage over low-level languages
A high-level language uses English-like statements, making it easier for humans to read and write. Advantage: Programs are easier to debug and maintain compared to low-level languages.
Questions this Programming languages and translators deck will help you answer
- › Give an example of when using an interpreter would be more appropriate than using a compiler.
Define 'high-level language' and provide an advantage over low-level languages.
A high-level language uses English-like statements, making it easier for humans to read and write. Advantage: Programs are easier to debug and maintain compared to low-level languages.
What is 'machine code' and why is it important for computers?
Machine code is the lowest-level programming language, consisting of binary instructions (0s and 1s) that a computer can directly execute. It is essential because the CPU can only understand and process machine code.
Explain 'assembly language' and its relationship to machine code.
Assembly language is a low-level programming language that uses mnemonics to represent machine code instructions. It's a more human-readable representation of machine code, requiring an assembler to translate it to machine code.
Describe the purpose of a 'compiler' and explain the type of code it generates.
A compiler translates the entire source code of a high-level language into machine code (or object code) in one go. It produces an executable file that can be run later independently.
Explain how an 'interpreter' differs from a compiler in translating source code.
An interpreter translates and executes source code line by line. It does not create a separate executable file; the code is executed directly by the interpreter each time it's run.
What is the function of an 'assembler'?
An assembler translates assembly language code into machine code. It converts the mnemonic instructions into their corresponding binary representations that the computer can understand and execute.
Distinguish between 'source code' and 'object code'.
Source code is the human-readable code written by a programmer in a high-level language. Object code is the machine-readable code produced by a compiler after translating the source code.
Describe an 'IDE' (Integrated Development Environment) and its common features.
An IDE is a software application that provides comprehensive facilities to computer programmers for software development. Common features include a code editor, debugger, and compiler/interpreter.
Give an example of when using an interpreter would be more appropriate than using a compiler.
An interpreter is more appropriate for development and testing, where rapid changes and debugging are frequent. Changes can be tested immediately without recompiling the entire program.
