Data vs. Information
Hi guys,
Today I had first ICT class. Class was very interesting so that we did not realize how passed 2 hours. As it was beginning of new trimester, miss Khairunisha, who is my lecturer, explained structure of the trimester, such as what kind of assignments we will be given. Especially, I liked activities during class. It was fun and enjoying as well as very useful to understand a topic. For example, we learned about information and data, but just explanation was not enough. First we wrote information about ourselves, then our lecturer explained by saying that paper written is data and when we use it it will become information. However, I was very happy after activity during class, because now I am sure about the topic.
In the 2 session of the week, we learned and discussed about IM (Information Management) and some of the problems relating to Information Management. IM is simply means gathering(from reliable sourses), keeping distributing (to the right people) data. We divided in group of four students and presented about some of the problems relating to IM. For me, it was interesting to know more about the IM and problems of it through discussing with my group.
Data,Information & Information Management
Under this title, we have to learned about differences between data and information, the economics and problems associated with information management. Firstly, I learned about computers.
Computers
A programmable machine that carries out what it has been instructed to do is called a computer.
The first generation of the computer came out in 1940. The 1st generation computers can named as Vacuum tubes. ENIAC is the 1st electronic computer and 18000 vacuum tubes were used to built it. And the first commercial computer is called UNIVAC.
Transistors
Transistors are the second generations of the computers. High level languages (COBOL and FORTRAN) are used in 2nd generation.
Integrated Circuits
The third generation of the computer was came out in1964 and called IC. Microchips combines thousands of transistors, entire circuits on one computer chip.
3rd generation users started using OS, keyboard and monitor.
VLSI/ULSI
In 1974, 4th generation of the computer has came out. The modern computers that we are using now are 4th generation computers.
Artificial Intelligence
The 5th generation of the computer called AI. It means computers can think, reason and learn.
We can categorize computers into 6 types:
Transistors are the second generations of the computers. High level languages (COBOL and FORTRAN) are used in 2nd generation.
The third generation of the computer was came out in1964 and called IC. Microchips combines thousands of transistors, entire circuits on one computer chip.

In 1974, 4th generation of the computer has came out. The modern computers that we are using now are 4th generation computers.
Artificial Intelligence
The 5th generation of the computer called AI. It means computers can think, reason and learn.
1.They are Embedded computers
5. Mainframes
What is data?
It is the raw facts.
It can be in the form of numbers, characters, symbols, pictures or even sounds.
It has no significance when it exists in that form.
It can be in the form of numbers, characters, symbols, pictures or even sounds.
It has no significance when it exists in that form.
It is data that is organized and meaningful.
Information is used for decision making.
Data is used as input for processing and information is used as output for this processing.
What is input?
In third session we learnt about input, output devices, storage devices and other peripheral devices. On that day we learnt what Input is and what the input devices are. It was very interesting. Input devices is hardware which allow us to enter data into the computer. The keyboard, mouse, touch screen pen input, game pad, light gun, digital cameras, voice input, video input as well as Scanners and some reading devices.. etc are the most common input devices that I have learned from from this session.
INPUT DEVICES
What is output?
OUTPUT DEVICES
Another part of the session was about the output devices. There we had to learn about Display devices, Printers and speakers.However the third session was quite interesting and important than the other sessions. I could learn more new thing from that session which will be helpful me in my future studies.Digital cameras as well as Scanners and some reading devices. Another part of the session was about the output devices.
Roles of information
We used information for decision making.
Information is used to influence and persuade.
It can be a capital resources, especially for companies that produce information -based products and services.
There are six qualities of valuable information:
Accurate, verifiable, timely, organized, complete and useful.
Data integrity
GIGO is defined as data integrity.
GIGO = Garbage in garbage out.
The economics of information and IT
IT has fundamentally transformed information availability, changing the economics and business practices in a wide range of industries.
Basic elements of information
1) Rich - is the number of people, participate, exchanging and sharing the information.
2) Richness - quality or quantity of information of information share in transaction.
The three components of richness are bandwidth, customization and interactivity.
Bandwidth - it's refers to data transfer. But in computer network, it refers to DATA TRANSFER NETWORK.
The rate is measured in Bits.
1) resource sharing
2) information sharing
3) promote communication and collaboration.
Information management (IM)
IM is the collection and management of information from one or more sources and the distribution of that information to one or more audiences.
How to mange your problem in information?
- web content management (CM)
- document management (DM)
- records management (RM)
- learning management (LM)
- enterprise content management system (ECMS)
