Take your first steps towards teaching GCSE computer science and establish a foundational knowledge base of concepts, terminology and classroom practice. Find out how the components of computer systems interlink and how these can then be connected together to form a network.
Learn about the different components of computer hardware, including devices not instantly recognisable as computers. The key components for input, processing, storage and output will be covered, and you’ll learn about the binary data that flows around and between computers.
Whether in your home or school, computing devices are increasingly networked. You’ll learn to recognise the technologies used to connect machines and to share data, and begin to find out how computers can communicate with each other seamlessly. You’ll also deepen your knowledge of some of the security risks that are commonly heard about in the daily news, which your students need to be aware of to be safe and responsible web citizens.
No prior experience or knowledge of computer science is expected before attending this course. It is advised that you become familiar with the National Curriculum in Computing before participating in this course, as well as the GCSE specification you are likely to teach.

An introduction to computer systems, networking and security in GCSE computer science
Recommended next steps:
This foundation course helps novice computer science teachers access the Computer Science Accelerator Programme. It is strongly recommended that its counterpart course An introduction to algorithms, programming and data in GCSE computer scienceis also attended before progressing further into the programme.
This course is delivered as part of the National Centre for Computing Education.
Who is it for?
This course is for prospective teachers of GCSE computer science who may be new to the subject, or who may teach computing in earlier years.
01 | Computer systems and hardware - Here you’ll learn about the breadth of hardware devices many of which will be familiar, such as keyboards, monitors and printers. You’ll understand how computers store, process and transmit data and the essential roles of the central processing unit and computer memory. Terms like ‘8 bit’, ‘500 gigabyte drive’ or ‘megabit broadband’ are in common usage – this session explains these terms and more.
02 | Networked computer systems. In the modern era almost all computers are part of a network. You’ll learn the essentials of how, and why, computers are networked locally, or globally through the internet. You’ll also find out about everyday internet services such as email and the worldwide web.
03 | Cyber-security - Networks bring risks as well as benefits. This session will demystify some internet dangers such as phishing, viruses and distributed denial-of-service (DDoS) attacks.
How long is this course?
This is a one-day course which consists of five hours of teaching time.
How will you learn?
You’ll engage with active learning in groups including direct instruction, hands-on activities and challenge-based learning. Examination practice with guidance will be linked to the specific requirements of the main awarding bodies. The course will model teaching approaches that can be taken back to the classroom.
- Learn how data is inputted into a computer, how it is processed, stored and output in a useful form
- Recognise the terminology used to describe data storage and transmission, ironing out common misconceptions
- Develop a basic understanding of local and global computer networks
- Become knowledgeable and confident in using common cybersecurity terms
- Learn engaging ways to bring these topics to the classroom
