What is data? What is Information? Where do computers fit into the data and information world?

Csc1010 - introduction


This is the "introduction" to the Introduction of Computing. We explore the differences between data, knowledge, and information and their uses. There is a short exercise at the end of the module.

We all have this end user computing frustration.

There are devices that cause frustration.

We have data input that causes frustration.

And sometimes we want to act out our frustration on computers.

Data, information,&Knowledge

This is the "introduction" to the Introduction of Computing. We explore the differences between data, knowledge, and information and their uses. This is a short exercise at the end of the module.

What is data?

What is information?

What is knowledge?

The distribution of understanding

What’s the difference?

Information = data + context

  • Group multiple pieces of data together
  • Establish relationships between data items
  • Provide context/framework for data
  • Interpret resulting combination

Validity of information

  • Valid Data ->Valid Information?
  • Not necessarily!
    • What if the data is incomplete?
    • What if the data is inaccurate?
    • What if the context for the data is missing?
  • If information is invalid, what happens to knowledge?

Where do computers fit in?

  • Computers store data.
  • Computers process data
  • Computers generate information

Data processing examples

  • Organize data
  • Calculate new data
  • Interpret data in a different format
  • Spreadsheets
  • Database management systems
  • Accounting software
  • Graphics manipulation programs

Visualation as a tool

Reflect and investigate

  1. Give your own example of valid data producing invalid information.
  2. Explore the Information is Beautiful website and find a visualization, either in the blog or the Our Data section, that you think does a particularly good job of turning data into information. Why did you choose this particular item, and what makes it so good?

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
how to fabricate graphene ink ?
for screen printed electrodes ?
What is lattice structure?
