ICT Notes, 18 November 2021

1. Data verification (recap)

• In order to reduce data errors:

  • Enter data twice

    • Same person enter data twice

  • Double entry

    • Different person enter data twice

  • Entering data twice can reduce error count as it is very rare that the two inputs will have the same error.

2. Presentation of information

- Why Powerpoint (not microsoft word) ?
    - Slides, multimedia elements, transition effects, animation effects, etc.
        - MS Word does NOT have any of these.
    - Separation of slides
        - Title, Text, Image
    - Timing, Fully automated slides (Timed presentation)
        - Links are useless as the slide is automated. When you click a link, the whole presenation should stop just for you to view the link which makes it unfavorable
    - Interactive
        - Interaction between user and computer.
        - If there are any actions that will happen after you click something, then that is interactive.
        - Examples include: button, links (When you click, the machine gives response, i.e. open the link. That's interaction :p )
        - Challenging question: is a Video in a powerpoint interactive???

side note: powerpoint sucks, use google's material guidelines to make a video is much better
