Learning Outcomes

On successful completion of this module students should be able to:

1. analyse a block diagram of a computer and explain how it works at the level of logic gates.

2. analyse and develop low level programs and describe how they are executed by a CPU.

3. describe how a computer performs input and output operations.

4. judge the applicability of high and low level language programming.

5. Explain the operation of a simple computer's CPU, memory and buses in terms of digital logic.

6. analyse and design simple logic circuits.

7. explain the operation of typical microcontroller I/O devices.

8. demonstrate an understanding of low-level programming operations on a microcontroller.

9. evaluate the applicability of contrasting CPU architectures for real world problems.

Brief description

This module examines what a computer is and how it works, down to the level of digital electronics. The module provides students who continue to study software development with an appropriate understanding of the hardware on which programs run and how programs are executed. The module will look at programming in assembly language and machine code.


Introduction and revision of what is a computer - 1 lecture
