Summary
Computers take many forms, from the smart watch on your wrist to the powerful machines used to predict the weather. They all share some key features and GCSE computer science students need to have a solid understanding of what makes a computer.
Take your first steps to opening up the computer, exploring the main components, their role and how they work together in computer systems. Learn about input and output devices, how memory is used for rapid storage and retrieval, and how data is stored elsewhere for long term use. You’ll explore different types of software, including the operating system and its critical role in managing all these resources.
Prior Knowledge:
You’ll need to know some basic concepts and terminology to access this GCSE-level subject knowledge enhancement. If you are entirely new to computer science, we recommend first participating in our one-day course: An introduction to computer systems, networking and security in GCSE computer science
Recommended next steps:
To compliment this course we also have Computer processors available – This course explores the CPU in greater detail.

Computer systems: input, output and storage – face to face
This course is delivered as part of the National Centre for Computing Education.
Who is it for?
This course is for current or prospective teachers of GCSE computer science with some understanding of computer science fundamentals.
Outcomes
You will:
- Develop knowledge of the key hardware and software components of a computer system
- Understand main memory, and the need for virtual memory
- Recognise the different technologies used to store large amounts of data persistently
- Calculate data storage requirements for different contexts and applications
