  • Now pretty much everything seems to be digital, from television and radio to music players, cameras, cellphones, and even books
  • we first convert the information into numbers (digits)

      It is during this conversion process that information can be lost. Depending on the process digital doesn't always capture all the gradations in analog data. Think of the difference between an analog clock (with an hour hand and a minute hand) and a digital clock (showing just hours and minutes). WIth a digital clock you can only ever see the exact minute 12:01am or 12:02am. The digital information doesn't show you the time between 1 minute past and 2 minutes past. But with an analog clock the minute hand is always moving. At halfway between 12:01 and 12:02 the minute hand will be halfway between the 1 and the 2 minute mark. If you look closely you will be able to see that it's halfway between.

      That is a really interesting point and not one i've reaaly thought about untill now.
  • People accept digital things easily enough, often by thinking of them as electronic, computerized,

  • It's not the same thing as time itself: it's a representation or an analogy of time

    To me analogue means the old and digital means modern, and i am kicking myself because I knew on the quiz that the TV was not digital but because I thought of it as a way to communicate I ticked true. I have a digital watch (fitbit) and I wear my analogue one as it does not go flat on me, the joys of digital technology.

    I actually thought similar to Susan, hence why I also chose true for the television question. I assumed ICT was any means of relaying information or delivery information, other than books or paper articles. Definitely a lot to learn regarding ICT

    What being digital means Being digital means more and more ICT devices are far more instant. They need to be mastered because this is the world we live in now even though there is still room for analog technology. ICT devices are all digital and is widely used in school and society itself.

    The teachers using effective pedagogy to help students in mastering ICT devices needs to be put into consideration in our local schools and community. The more ICT devices are explicitly taught, the more school community and activities around ICT become accessible in our classroom.
