LO1 Data and Information

                This week is my first week in Foundation Study Program (FSP). First at class there are a few group of students make presentation about this topic. My friends and I just finished IEP so we join litter bit late that why we only see them present.

At secondary school I also learn Information Communication and Technology (ICT) so it is quite same. My lecturer, Miss Khairunnisa has taught me many things in the classroom. In this topic I have learned about computer. IT class of course we need to know what is computer and then we continue with other sub topic.
Actually the meaning of computer is a device that computes, especially a programmable electronic machine that performs high-speed mathematical or logical operations or that assembles, stores, correlates, or otherwise processes information. From start computer has created there are five generation of computer.

I also learned about category of computer. Computer have six category such as:

1.  Embedded computer. Embedded computer is a technology that can give benefit to people for example traffic light, ATM machine and etc. A mini computer embedded into a specific product for a specific function.
2. Mobile computer, this computer is the computer that fits in our hand like mobile phone. Nowadays, there are lot kinds of phone that same function like computer. This computer also contains built-in computing or Internet capabilities.
3. Personal computer, the computer that designed for single user at a time and it is fully functioning portable or desktop computer. Many people use this computer help them in doing work and example of this computer are laptop, notebook and ultrabook
4. Midrange computer, this computer is like small cabinet or rack that can host data and programs available in small group of users. Example of midrange computer is midrange servers.
5. Mainframe computer, the computer that is large, expensive, very powerful computer that can handle hundreds or thousands of users in a same time.
6. Supercomputers, the computer that is more fastest, most powerful and most expensive category of computer. This computer extremely powerful computer used for complex computation and processing.

After I have learned about computer our lecturer explain about data and information. This lesson very important because we need to know data and information .Data and information is different thing it is very different between each other. Data is a raw facts. This means data can be in the form of numbers, characters, symbols, pictures or even sounds also. In addition, it has no significance when it exists in that form. In addition, information means data that is organized and meaningful. Information also have two basic elements. First is reach means the number of people who participate in sharing information and second is richness means amount of quality information shared in transaction.

Computer system base from I learned is a computer converts data (from input) to become information (as output). Information processing have their own method to process data example input, processing, and output. Input is any data and instructions entered into the memory of a computer after that processing of data exist in CPU and CPU will process data and then output is that data which is has been processed into a useful form.

The last one that we learned in this topic is information management (IM). IM is a general terms that refers to managing any kind of information. Peoples and organisations are confronted with many information management problems and issues. The solution for this is deploy a new technology for example electronic records management system, learning management systems and customer relationship system.
