This course is the sixth of the eight courses in the collection Computing for School - Communication and Networks.
The course is for anyone who wants to know more devices that make up the Internet and how they work together to provide a global communications network. It introduces the concept of a layered model and explains the role of switch, routers, WAPs, modems. It also gives examples of the clever ways bad people will try and use the Internet and what you can do to be safe online.
It is an 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.
