Communication & Networks – Black Level

The Computing Progression Pathways suggests that at the black level, on the theme of Communication & Networks, a student should demonstrate that he/she:

  • Knows the purpose of the hardware and protocols associated with networking computer systems. (Abstraction) (Algorithmic Thinking)
  • Understands the client-server model including how dynamic web pages use server-side scripting and that web servers process and store data entered by users. (Abstraction) (Algorithmic Thinking) (Decomposition)
  • Recognises that persistence of data on the internet requires careful protection of online identity and privacy.
