These resources will be removed by end of Summer Term 2025.

Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.

These resources were created for remote use during the pandemic and are not designed for classroom teaching.

Lesson details

Key learning points

  1. Computers run programs and code exactly as it is written.
  2. Low-level languages provide direct control over hardware.
  3. High-level languages use abstraction to make programming more human-readable.

Keywords

  • Low-level language - programming languages that require the programmer to use terms that are aligned to the operations of a specific machine

  • High-level language - a human-readable language written in formal, structured English

  • Compilers - a compiler creates an executable file for a program by translating a high-level language to machine-readable code

  • Interpreters - an interpreter translates and executes code line by line, then translates it into machine-readable code

Common misconception

High-level languages are always better than low-level languages because they are easier to use.

High-level languages are generally easier to learn and use. However, low-level languages offer more direct control over the computer's hardware, which can be essential for certain tasks like writing operating systems or device drivers.


To help you plan your year 10 computer science lesson on: High and low level languages, download all teaching resources for free and adapt to suit your pupils' needs...

Connect the concepts of high-level and low-level languages to real-world applications. High-level languages are used to create everyday software like web browsers, while low-level languages are used to develop the operating systems and hardware drivers that make those applications possible.
