First week in ICT Class...A new experience

Ice-Breaking Session
1st session

We started our class with ice-breaking session. First our lecturer introduced  himself with the name Mr. Azamuddin AB Rahman. Everybody was intruduing himself/herself and often there created a serial of jokes with the pronunciation of students name.It was so funny moment and great that he was so free and soon got mixed with us. Then he talked about overview of the course outline,tests and assignments.

Basic concept on computer and the computer components
2nd session

We learnt about the basic of a computer. I saw some of us were advanced and some of us were backwards. But our lecturer made evereything easy for us. The first question was what is a computer?
computer is a machine that can do mathmetical operations and information processing. Next point was about the Computer Operations which  include
1. Input
2. Processing
3. Output
4. Storage
In the next slide we learnt the about the difference between data,information and the basic concept of Hardware and Software.

Hardware includes: Input devices,Output devices,System unit,Storage devices and Communication devices.
Software includes: System software and Application software.

Then we learnt about Computer Characteristics are those are- Speed, Reliability, Consistency, Storage, Communication and so on.


                                               Computer Components (Hardware)
Number System:
3rd session

We learnt about the four (Decimal, Binary, Octal and Hexadecimal) number systems.          

Decimal: It uses tens numerals to from a string of numbers. The values are 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9.
Binary: 0 and 1 are the only two numerals of Binary number system.

Octal: Octal number system uses 8 numerals and they are 0,1,2,3,4,5,6,7.
          
Hexadecimal: Hexadecimal number System uses 16 symbols including numerals and letters. They are 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E and F.




Later we learnt how to convert from Decimal to Binary, Octal and Hexadecimal and from other numbering system to Decimal. For some of us it was totally a new topic.

And there was an in-class activity which motivated us in learning how to convert decimal, binary, octal and hexadecimal within one another.


Reflections:

After the 1st week finished we learned basic concepts about computer. We learnt -

1. Computer is a programmable machine which can not only does computation but also does a lot of things including entertainment, knowledge sharing and information storage and so on.

2. There are two types of computer components: Hardware and Software

3. We learned about the classification of Hardware and Software.

4. We also got to know about Different Numbering Systems and how to convert them from one to another.

5. Finally we also understood this number system helps human's instructions to convert to computer's understandable language.
