  • To learn about cabling types and be made aware of the pros and cons of each type of cable.
  • To be able to both define and choose the most appropriate topology/medium applicable to a given scenario.
  • To be able to describe transmission technologies and different networking devices. Students will also be able to describe the device and its functions, as well as when and where it is used.
  • To be able to define the important terminology associated with Normalization, as well as discussing the concept of Normalization, the reasons for Normalizing a database and the characteristics and requirements for each normal form.
  • To be introduced to the crucial concepts of what an algorithm is as well as detailed explanations of:
    a) How to assign values to variables;
    b) The operators used for calculations;
    c) How to indicate an entire array as opposed to a single item of an array;
    d) How to represent each of the programming structures;
    e) How to represent and call methods.
  • To be made aware of the terms that are most often tested and a broad overview of the evolution of the Web. Students will be shown how to apply the terminology to a given scenario and give appropriate examples of the aspects covered. Additional important aspects, amongst others, are: Downloading vs Streaming, Lossy vs Lossless Compression and Client-side vs Server-side Scripting.
  • To revise advanced concepts in SQL. Aspects such as the sequence of instructions, TOP clause, Insert, Update, Delete, Insert using existing data, Joins: INNER, LEFT and RIGHT, Date functions, String (text) functions, Data aggregate functions, Group by, Having, The use of IN, Nested queries and generating random numbers.Additionally, newer concepts to be tested at the end of this year, like formatting dates and numbers and extracting characters from randomly generated positions within the text etc.are discussed.

The Information Technology MasterClass Series of videos was produced to highlight, clarify and refine the most important concepts as described in the Examination Guidelines document for Information Technology.

An effort was made to address the more difficult concepts and the focus was on revising and clarifying most frequently examined concepts, rather than on reteaching. Most of the theoretical concepts outlined are from the Grade 11 Examination Guidelines, which form the bulk of the theory examination. Helpful hints and what students need to watch out for when answering examination questions are interspersed within the content.

After each video, students should take some time to consolidate their understanding of the concepts discussed, by attempting to answer questions from past examination papers specifically on that particular topic.
