We've already made a computer system general introduction, we are talking about the development of the computer, the hierarchy of computer systems and computer performance, then we have to learn from the beginning of this chapter representation and operation data.
So what does this chapter, we will learn, as well as representation among a number of computer data among computers is how to represent, and how to design a calculator calculation method based on representation and the number of computers among. The main contents of these three parts of it will be a focus of our chapter. First, we must understand what is called the representation of data. Data indicating means can be directly identified, and the computer processing hardware among the data types, can be directly identified hardware and processing means for processing comprising instructions for these types of data in a computer system among a set of instructions. Then the computed data in the instruction, we must use hardware to implement the operation in which the system. Among these processes, we have to analyze the data comparison method, and to improve, and then in the times of our study on the basis of these algorithms is how to use the computer in which the hardware and then give the appropriate hardware. So this is the main content of our representation and operation of Chapter II data.
Then we enter the first section of the study, called the first number and coding.
The main content of our what does this section, we are going to introduce the first binary notation, then we are going to learn how the different numbers between hexadecimal is converted. Then we will learn a coding method called the BCD code. Next we will learn how the characters and the string is represented in a computer. Finally, we will explain the check code.
