First Post ,10.10.12

                         Hi, I'm Rabbi, It's my pleasure to be able to create my blog and now i am going to share myself with all. My computer and Internet course is under one of my favorite and respected lecturer Mr. Azamuddin AB Rahman.
                 
                 
                 week 01 

First day of our class was so excited and important for us. Mr. Azamuddin gave a short but valuable speech regarding our course. Then he explained to us the overview of our course outline as well as assignment. Then he started to describe what is computer and its components. 

      Computer and it's main components 

Computer is a programmable device that can perform mathematical operations and process information. After that we learned about its operation which includes 1. input
            2. output
            3. processing 
            4. storage 
We also learned about the difference between data and information. Then lecturer described hardware, software and its classification.     

                      Computer's Hardware

Hardware is the electrical, electronic and mechanical parts of a computer. It includes 
            1. Input device
         2. Output device
         3. System unit 
            4. storage device
            5. Communication device

    

                                  Computer Software 
Computer Software is known as a program series of related instruction organised for a common purpose.
                               
                     Types of Software

                 1. System Software
                 2. Application Software

                 Number system of Computer

At the end of the first week we leaned about the Number System of Computer.   It has four types of Number System. They are Binary, Decimal, Octal, Hexadecimal.

                    Binary             : It is two base number system. It has only two numerals and they are 0 and 1.

                   Decimal              : It is ten base number system. It has ten numerals and they are 0,1,2,3,4,5,6,7,8 and 9.

                    Octal               : It has eight numerals and they are o,1,2,3,4,5,6 and 7. It is eight base number system.

                 Hexadecimal  : This 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. It is a sixteen base number system.

            
  Reflection 

Finally after passing first week I learned Computer is a programmable machine. It has two types of components : Hardware and Software. I also learned about different parts of hardware and classification of software. After that I learned about the number system of computer and how it helps human's  instructions to convert to computer's understandable language.
