Week 1
Induction about
Computer
This is my first week in my second semester, it was very
interesting to started my first class in the morning at 8.00am with my
lecturer, Mr. Azamuddin Abdul Rahman or well-known as Mr.Azam. Therefore, my
friends and I began it with getting to know each other and introduced ourselves
accordingly. Most of us have learnt the Information technology (IT) and
Information Literacy (IL) in the previous trimester 2012. So that, we can
easily follow this course and ready to get a lot of knowledge regarding
computer and internet field.
Studying in new course is something differently what I felt during my
first-class with new lecturer as well as new classmates. However, it was a
great time for me that I could learn something really useful in my life from my
lecturer. He gave us a huge of knowledge that he has regarding Computer and
Internet field. Furthermore, I learnt what I had learnt in IT class before, so
that it was just a re-frees for me to know more about computers.
So, as the above picture shows that Computer is a
programmable machine that carries out what it has been instructed. We recognize
a Computer by looking at physical features as well as behaviors. In a Computer,
there are some operation systems that always it does, such as Input,
Processing, Output, Storage, and the other is Communication, and this operation
is called as Information Processing Cycle.
In Addition about Computer
Operation, here are some definitions of Information Processing Cycle:
a) A computer converts DATA (from Input) to become
INFORMATION ( as Output).
b) Processing requires a set of instruction, known as
PROGRAM or SOFTWARE.
c) A computer holds data, instructions and information in
storage for future use.
Data is a collection
of unprocessed items such as text, numbers, images, audio and video. Then what
is the related between Data and Computer? The explanation is Computer and its
components convert or Process Data (as input) to become Information (as output)
in order to be useful for people (users).
Another thing that I have learnt from the class was
Computer Data Representation. It was a little bit difficult and I was really
confused how to compute it. Basically, it is how a Computer represents the data
and it is called a bit. As addition, a bit is the most basic unit
of information in a computer, and a group of eight bits is called as a byte,
the smallest possible addressable unit of computer storage.
What I have been
learning in the Computer and Internet class is very different from what I
learnt in Information Technology last trimester. In the Computer and Internet
lesson, I have to compute such the number systems that data can be represented
by a Computer. They are called as Decimal Number System, Binary Number System,
Octal Number System, and Hexadecimal Number System.
In addition, I would
like to explain about all those number systems accordingly, even though I am
not very expect in calculate them.
