Soft exam (I) Overall summary

It has been more than a month before the soft exam preparation. After watching the xisai video, I read the soft exam books on both sides. The soft exam involves a wide range of knowledge, but most of them are previous knowledge. When I first started to read a book, I felt a lot of knowledge and it was very messy. After some dredging, I sorted my knowledge and it instantly became much clearer, see:

Graph export ideas:

On the whole, I divided the soft test into three categories: Computer, software engineering, and other information security and standardization knowledge, our examination is called the National Computer technology and software professional technical qualifications (level) examination, so it is not difficult to understand the whole is divided into these three parts, first of all to have a detailed understanding of the computer, then, we use the idea of software engineering to develop and make software. Of course, information security and standardization are indispensable in the development process. It is the guarantee of our technical practices.

First, the computer part

There are two modules: Computer Basics and computer systems. Computer basics, mainly related knowledge of mathematics, the most basic underlying knowledge of computer data processing, such as the number conversion, ASCII code, and the representation of computer internal data. Teacher Mi said that there are only two numbers inside the computer, namely 0 and 1. Through encoding and decoding, the computer presents various powerful functions. What a magic thing is this.

After understanding the working principle of the computer, let's take a look at the computer system. Since it is a system, it is an integral part of the computer. Here I divide it into four parts, hardware, software, network, and multimedia.

(1) Hardware

This section mainly introduces computer hardware, including the central processor, storage system, I/O device and command system.

(2) Software

If hardware is the human body, software is the human soul. The software involves a little more knowledge, but in the final analysis, it is for a single purpose, that is, data processing. Before software is available, people need an input command, which is complex and complex. With the language, people can compile a set of commands in advance, store them in the machine, and start the command, the computer can automatically execute a task. According to the data processing process, I connected the knowledge of the Software. Although it was far-fetched, the overall process was probably like this.

(3) Network

The remaining network represents the expansion of computing. It indicates that a computer is used for collecting, processing, and transmitting information more than just a computing tool, and resources are shared and combined. This section mainly describes the architecture, related devices and protocols of computer networks.

(4) multimedia

Multimedia is the integration of multiple media, including text, sound, graphics, images, and animations. What we need to know is their related formats, and how they are stored in a computer.

Secondly, the softwares Section

This part is not familiar to us anymore. The object-oriented technology is one of the software development methods and will not be described here.

Finally, information security and standardization

Knowledge about security includes computer system security, network security, complete information, encryption and decryption, etc. This part of knowledge is also very important, and information is priceless, to achieve information security, you must understand relevant knowledge. The last part is the standardization part, which is divided into standardization, informatization and Intellectual Property Rights, which guarantees the smooth development of computer and software technologies.

Conclusion: The soft exam is a systematic summary of the theoretical part of computer knowledge and soft engineering knowledge. Although computer technology is a very practical computing, it cannot be left without the support of theory, and its importance cannot be ignored. This article is mainly a macro summary and will be summarized in detail later.
