Computer networks exist all around us. During the course, you will demystify the hardware and network topologies used for data transfer between computers and help you make topic learning relevant and engaging to students.
Learn how computers of all shapes and sizes are connected physically, or wirelessly, and how this arrangement affects how data is shared. Switches, routers and other network components will be fully explained, helping you understand how data is moved around in packets.
This course will deepen your knowledge, up to GCSE level which will help boost confidence when teaching key topics to students.
Book now and you will be automatically registered for the scheduled sessions for the course. Remote CPD courses have live, facilitator-led sessions and are not available for instant access. Please refer to the schedule of dates published for each course instance.
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.

Who is it for?
This course is for current or prospective teachers of computer science with some understanding of computer science principles.
- 01 | Reasons to network & hardware – step into networking and explore the reasons networks exist including the benefits of using networked computers. Explore the different hardware that is required when building a network including routers, switches and hubs.
- 02 | Network types - Consider the different types of network and their characteristics including personal, local and wide-area networks.
- 03 | Topologies - examine the different network topologies required at GCSE level including ring, bus, star and mesh networks.
- 04 | Topologies in action – explore network topologies in further detail, compare the characteristics including how data is transmitted and suggest topologies for given scenarios.
- 05 | Data transfer – explore how data is transmitted across a network in the form of packets, understand why files are broken down and the purpose of packet switching.
- 06 | Transmission and media – explore how data is transferred using wired and wireless networks including understanding the use of data frequencies and Wi-Fi channels. Consider the importance of encryption when using Wi-Fi and the factors that can limit a Wi-Fi.
How long is this course?
This course is approximately 5 hours in duration, split across several days.
This course is delivered as part of the National Centre for Computing Education.
