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.
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
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.
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.
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.
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.
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.
