Topic 1- Data, information, and information management



 In this topic, my lecturer started to explain and gave us a good revision about what I have studied in my previous course introduction to computer. Therefore, she explained that computer has five operations which are input, output, processing, storage, and communication. she also said that computer has been  through five generations. The first generation such as ENIAC and UNIVAC, the first commercial computer, used vacuum tube. The second generation such as IBM 1401 used transistor instead of vacuum tube. Therefore, the size of computers has been reduced. The third generation used integrated circuit (IC) that combines thousands of transistors. The fourth generation such as personal computer used very large scale integration (VLSI) and ultra large scale integration (ULSI). The fifth generation used artificial intelligence which means computer can think, reason, and learn. After that the lecturer mentioned the categories of the computers which are embedded computers, mobile computers, personal computers, midrange servers, mainframes, supercomputers, and hybrid computers.
                            

After that, the lecturer gave us a small activity and asked us to give the different between data and information. Then we discussed the answers in the class. Therefore, the correct meaning for data is raw facts. However, the correct meaning for information is data that is organized and meaningful. Therefore, the computer can convert data to be information by using I-P-O method which include input, processing that happens in the CPU, and output. Afterwards, I learnt some roles of information which are information used in decision making. It is also used to influence and persuade, and it can be a capital resources. I also learnt that information has two basic elements which are reach and richness. Reach means the number of people who share the information. However, richness means the quality of the information shared in transaction and it has three components which are bandwidth, customization, and interactivity. Bandwidth is the amount of information that be moved from sender to receiver in a given time. Customization means whether the information is tailored for an audience of a particular size. Nonetheless, interactivity is between two parties.

In the second part of this topic I learnt about information management (IM). Therefore, I understood that IM is a general term that refers to managing any kind of information. I also learnt that IM is created by technology and it is same like IT. However, there are some problems with IM such as disorganize data or information, and information overload. Therefore, to solve these problems, we need to use new technologies such as learning management system (LMS)
