12. Why is this important? Broad range of information that will be at least partially relevant no matter where you work. Later courses will build upon the basic knowledge that you have received here. This basic knowledge is necessary to proceed into more complex topics that will be presented in later courses.

13. What does IT mean? IT –Information Technology Key to the Future? –Tonga and Computers Makes work faster and more efficient? Instant Communication Storage of large amounts of data in small space Necessity for the modernization of Tonga. –Will become a part of daily life

14. Cont. There are many levels of computer users. The most basic are those who type documents. The TIHE program is trying to turn you into one of the most advanced kind of computer users. These are the people that make programs that other people use. Along the way, you will also be expected to learn how computers really work, aspects of networking, information management ideas and many other topics.

15. Cont. One common mistake people make is that they think Information Technology is fixing people’s computers. Information Technology is about trying to use technology to work and manage information better. If you want to fix computers, what you need to know are the different pieces in the computer. Then it’s just a matter of connecting cables and wires. You don’t need to go to school to do that. You just need to take a computer apart.

16. Cont. You might also believe that IT is about making computers. People who “make” computers spend many years getting their Ph.D. and then work in billion dollar factories using other computers to help them make new computers because it is so complicated. Stores that sell computers just get the different pieces and put them together, which does not need years of schooling or expensive equipment. All you need to know is how to connect things.

17. Cont. You will learn all these things and more in this class, but it is important to remember the focus of the IT school. This focus is to teach students to use computers to solve problems in organizations. This might mean making a program or it might mean using a database instead of excel. Someone “made” Microsoft Word to help people work better (and to make money). Your goal is to be able to make useful programs after two years.

18. Remarks This course is the first step to understanding about computers. It presents all the different topics that are related to computers. By the end of the course, you should be familiar with all of these topics and be able to engage in meaningful discussion with your peers.
