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

Csc1010 - introduction

Computing?

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?

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 are the products of Nano chemistry?
Maira Reply
There are lots of products of nano chemistry... Like nano coatings.....carbon fiber.. And lots of others..

what about nanotechnology for water purification
RAW Reply
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
Professor
I think

Nasa has use it in the 60's, copper as water purification in the moon travel.

what is the stm
Brian Reply
is there industrial application of fullrenes. What is the method to prepare fullrene on large scale.?
Rafiq
industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong

write examples of Nano molecule?
Bob
The nanotechnology is as new science, to scale nanometric
brayan
nanotechnology is the study, desing, synthesis, manipulation and application of materials and functional systems through control of matter at nanoscale
