General
This course is the seventh of the eight courses in the collection Computing for School - Communication and Networks.
The course is for anyone who wants to know in detail about how the TCP/IP layered model works, which devices work at which layer and how one IP address can be shared by a single house for many devices. It also looks at some hard hitting stories about the dangers of posting online.
It investigates the operation of the protocols within the TCP/IP protocol suites, discussing the services they provide for user applications. Network device operation is examined in more detail, with particular attention paid to how they interact with the TCP/IP protocols within the LAN. NAT is revisited in order to investigate its operation in larger networks, where multiple devices require its services.
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. http://cs.co/ComputingForSchoolsCourse
