The internet was created in a gradual process of slowly emerging technologies. For the activity we participated in each group got the name of someone who aided in the formation of the internet our group recived Alan Turing who helped to break the anigma machine code and after the war started to work on one of the first programs for a stored computer program.
this video raises an interesting point about social media privacy on the internet and how it can be affected by friends.
Core Topic: Data Handling
Data can be collected from a wide range of sources including digital media, printed work, audio or your own work. The data must be entered useing the correct format eg. WAV for an audio file. It is important students learn the correct file formats to use when saving thier files because it may lead to a loss in information eg. if a video file is saved as an audio file the visuals would be lost. you could get an image like the one below and get students to learn the file types and do a little quiz with the students.
The data may be created to be printed as a document, to be tranmitted via the internet or to be displayed on a screen.
Students should learn the difference between digital and audio waves. They are stored in binary form using 0's and 1's as a set of digital values.
There are 5 main data types including text, numbers, video and animation, audio and graphics.
we should teach students to be aware of data secturity issues such as viruses and spyware and how the use of firewalls helps to keep data safe. You could use these exmples to have a discussion on the ethical issues related to the people who create these data safety issues. They should be taught that hackers and people who comit identity fraud commit illegal offecnces and that it is wrong and there are legal conciquences to these actions.
