Summary

The unit is subdivided into six topics (plus a test) in order to fit with most school timetables. It is a theoretical unit covering all of Section 3.9 on Fundamentals of Communication and Networking and 3.8 on Consequences of Uses of Computing from the AQA AS Computer Science specification.  It builds on the fundamentals covered in both the Key Stage 3 NC and our unit on Networks as well as the GCSE AQA and OCR units on Networking and then extends this knowledge to a level sufficient for examination purposes. Students learn about:

  • Communications methods, including baud rate, bit rate, bandwidth, latency and protocols
  • Network topologies, including physical star and logical bus
  • Client-server and peer-to-peer networking
  • Wireless networking, including CSMA and SSID

The unit concludes with two lessons on communications and privacy and the social, legal and cultural issues presented by the use of computers and communication methods in today’s world.

No specific software is required for this unit beyond a standard office suite of applications for the presentation and printing of provided resources.
