TOPIC 1

During the first week of Information Technology ,our lecturer brush through what we learnt at Computer and
Internet in the likes of definition of computer, the categories of computer namely:
Embedded computers,Mobile devices/ computers,Personal computers,Mid range servers,Mainframes, Supercomputers, and Hybrid computers.Also, the generation of computers, the basic operations a computer can perform etc. Actually, we have five generation of computers that is from the First generation(Vacuum Tube) to the fifth generation(Artificial Intelligence-Now and the future). Further from the week lessons, I learnt about Data and Information and below is a summary:

Data is a collection of facts, figures and statistics related to an object and  can be processed to

 create useful information whiles Information is the manipulated and processed form of data. 

Much more, computers process data into information.     

             Much more Information plays three role which are:

1. Information is used to influence and persuade.
2. Information can be a capital resource, especially for companies that produce information-based products and services.
3. Information is used in decision-making.

Furthermore, information has two basic elements namely Richness and Reach. The richness has further three(3) components known as Bandwidth, Customization and Interactivity. A computer uses the "IPO" method to convert Data into Information, hence "IPO" stands for Input ,Processing and Output. An input device is any hardware component that allows users to enter data and instructions into a computer whiles An Output device  is any type of hardware component that conveys information to one or more people. Below is an examples of input device:

         

Below is also an example of output device:

     

The CPU is main brain of the computer. It is where all the calculation in a computer takes place. It consists of three basic part namely Arithmetic and Logical Unit, Control Unit,and  Registers. Below is a diagram view of the parts.

A      Actually, we did learn what is Information Management,Problems associated with IM, and the necessary solutions. We were also given an assignment to find the problems of IM and the solutions. This task broaden my mind since it was a group assignment where I had numerous discussion with my group mates. IM is the the discipline that covers the definitions, uses, value and distribution of all data and information (organization OR whether processed by computer). Some problems of IM includes Data Lost,Lack of Storage, Unreliable Information,Hacking,Virus,Unreliable Information,Incomplete Information etc.

This  is among some of the  knowledge I acquired in  Topic 1.Thank You.
