Hardware ^_^

Assalamualaikum,

    In this week, I had learnt about hardware, this topic quite long, so we need to cover this topic for 2 weeks. However, I already learnt it in the previous trimester which is in Information and Technology class. As we know, computer is a programmable machine that carries out what it has been instructed to do. Hence, there are 5 basic operations a computer can perform; they are Input, Processing, Output, Storage and Communication. From what I had understood, hardware is the physical parts such as keyboard, mouse, CPU and etc.

    Besides that, a “Bit” is the most basic unit of information in a computer that is represents data. A “Byte” is a group of 8 bits (8 Bits = 1 Byte). Then, this is my favorite part because I need to calculate that is number system. There are 4 number systems, that are Decimal which is B₁₀ and the value are 0-9, the second is Binary which is B₂, they are 0 and 1 also known as BITS. The 0 represent for OFF and the 1 represent for ON. Then, Octal which B₈ and they are 0-7. Lastly, Hexadecimal which is B₁₆ and its use 16 symbols (Numerical + Letter) that are 0-F. At the first time, I was confusing to count it, but when Mr. Azamuddin gives more example I can get it, oh it not difficult than I thought. From my understanding, when we want to convert decimal to binary, octal, and hexadecimal we need to use division method. Then, when we want to convert binary, octal, and hexadecimal to decimal we need to use multiplication method.

I think that all from me today and do not forget to smile… ^_^
