Welcome to Term 3! I hope you had a good holidays. Before we kick off today's lesson in earnest, we need to do a little bit of housekeeping first. The end of the preliminary course is in sight - so I think it will be helpful for you to have a roadmap of where we're going to be going in the next couple of months or so.

What will we be doing?
Transmitting & Receiving
Group Project (work + interviews)
Exam preparation
Preliminary exams

In some senses, you could probably have put that all together by yourself - but at least now we're all on the same page! =) Alright, now onto today's lesson.

Introduction to Transmitting & Receiving
  1. Define transmitting and receiving.

  2. Identify five examples of this process that occur in your day-to-day life. In each case, identify:
    • The data being transmitted
    • The source and destination of data
    • The information technology involved in the transfer

  3. Define a "bus", and describe the primary types of internal and external buses (make sure to refer to the main kind of data that each bus is intended to transfer).

  4. Explain the role of a modem in transmitting and receiving.

  5. Identify four distinct methods of connecting to the internet. For each method, describe:
    • Unique benefits
    • Relative cost
    • Infrastructure required
    • Approximately when it became mainstream (i.e. easily available to consumers and affordable)
