Week 12: 3.2.4 Transfer of data in ICT systems

This week we’re going to begin a topic more commonly known as computer networking. It will take us the two weeks (12 & 13) to get through it. initially, we’ll look at the teach-ict website and discuss the following:

  • What is an ICT Network?
  • What is the difference between a LAN and a WAN?
  • What are the advantages and disadvantages of computer networks? 
  • Protocols, Topologies and Transmission modes
  • Hardware and Software for networks. (Consider mobile phones, pdas and other portable devices.)
  • The Internet and the WWW, including email and other methods of electronic communication.

A series of short videos on my delicious will illustrate some of the above, (dated 23rd November) and when they’ve been watched, you should attempt the interactive network construction on this link.

The powerpoint summary can aid revision of this section, as will the set of notes originally from fatmax and North Chadderton. Always use current textbooks as well, to update these for the new specification.
