An introduction to computer systems, networking and security in computer science - remote CB438 / D21
Take your first steps towards teaching computer science and establish a foundational knowledge 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.

Who is it for?
This course is for prospective teachers of computer science who may be new to the subject, or who may teach computing in earlier years.
What topics are covered?
- 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 | Hardware - further develop your understanding of key hardware components by learning how they function together.
- 03 | Networks - 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.
- 04 | Protocols - learn how network protocols are used to communicate over a network.
- 05 | 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 will you learn?
Scheduled live, interactive online sessions led by an experienced practitioner.
Flexible facilitator-supported, participant-led tasks, involving deep exploration of the subject content.
How long is this course?
This course is approximately five hours in duration, split across several days.
This course is delivered as part of the National Centre for Computing Education.
Who is the course leader?
- 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
