This collection has been developed for teachers of School children aged 5-16, based on the UK's National Curriculum for Computing. The collection initially provides an introduction to the Internet and the services it provides, with an emphasis on security awareness and personal safety considerations when online.

The content and organisation of topics is based on the CAS Computing Progression Pathways guide developed by Computing at School (CAS). This collection focuses on the Communications and Networks Theme.

Schools interested in using these materials as part of the National Curricula are free to do so. Additional teaching resources to support the delivery, manage classes and run quizzes are available for free to schools by registering to become a Cisco Academy.

Further work is underway to develop additional collections, with the next being the Hardware and Processing theme. It will develop an understanding of the purpose and operation of the hardware and software elements required to support a typical home network that connects to the Internet. Understanding of key concepts is reinforced with practical activities within a simulated network environment, and regular quizzes allow students to gauge their level of understanding as they progress through the collection modules.

  • Identify network hardware and protocols

    Identify network hardware and protocols

    Introduction to the TCP/IP protocol suite, identifying the protocols used to support IP network communication, and briefly discussing their purpose.  Network hardware devices are introduced, and their relationship with TCP/IP protocols is discussed. The www transfer between web browser/server is revisited, introducing the basic concepts of network address translation (NAT) in small home networks. Internet security is further developed, with an emphasis on protecting network devices from external threats.
