Computer Hardware 1

Assalamualaikum...

Hai!! This is my second trimester in foundation. So, for ICT course, I chose to study Computer Internet in this trimester. Actually, I have taken Literacy for this trimester but when I came to class, I realized that many students have taken the subject and the class was seem very crowd. Then, I came to Computer Internet class to see the situation and it was cool and more relaxed.

Before Mr. Azzamudin teach us the first topic in Computer Internet. We had been briefed about computer by him. Computer is a programmable machine that perform tasks or calculations according to a set of instructions or programs. Also, Mr. Azzamudin explained to us about components of computer (hardware and software) and the elements of computer (input, output, storage, communication, and processing).

Next, Mr. Azzamudin taught us about computer data representation and numbering system. Data representation is a methods used internally to represent information stored in computer. Computers store lots of different types of information such as texts and numbers. Computers work with a binary number system that consists of only two digits which are 1 and 0. One digit in binary number system is called 'bit' and a combination of 8 bits is called byte. There are 4 types of number system which are binary, octal, hexadecimal and decimal.

Conversion from decimal into binary

Conversion from others numbering system number into decimal

This topic is quite easy but I got confused about numbering system at first. I got confused how to convert them into others number system. However, Mr. Azzamudin gave us many exercises how to convert the numbering system. Lastly, I didn't get confused at all.
