For the purpose of career, then there is absolutely no need for us to study in computer school. If you have a career goal but lack interest, it will be difficult for you to stick to it. Therefore, if you have the intention to engage in related occupations, please teach yourself before you officially start studying. We can find many similar tutorials to determine whether you are interested in this industry and the motivation to stick to it. Well, first start from scratch, the computer, and then do you know the basic operation of the computer? 1. Open, close and restart 2. Basic knowledge of computer: how to use keyboard (input method) and mouse, what are hard disk, USB flash drive, CD-ROM drive and floppy disk, how to start software, how to operate (open, close, delete, move, rename and edit) files, how to install and uninstall software, and how to use browser. 3. Basic knowledge of the system: what is the operating system, the use of built-in functions and software (Windows Notepad, resource manager, drawing, task manager, start menu and taskbar, Linux terminal, vi editor, etc.). ), and the use of common shortcut keys in the system. 4. Common software: the basic structure of the graphical interface (title bar, menu bar, address bar, toolbox, etc.). ), how to quickly understand a software, commonly used software (Office or WPS, PhotoShop, AdobePDF, IE or Edge or other browsers, compression managers such as Haobi or WinRAR, download tools such as Thunder or FDM, etc.) and download (sometimes need to be cracked). Then, if you want to go deeper, you need to get in touch with more professional things, such as programming and databases. Most people learn computers by using them. Of course, you can also take the road of hardware to repair the computer, which requires you to understand the various hardware components of the computer and know the relevant knowledge of electronic circuits. Not much to say here. To learn computer further, you need: logic circuit foundation, microcomputer principle and interface, assembly language, operating system, C language, C++ language, and then: 1 Control Department: MCU principle, embedded and Linux, network foundation, TCP protocol, knowledge of Internet of Things II. Design department: Java language, HTML+CSS+JavaScript, JavaWEB (including common ones). Linux system (server-side programming) or Android-related (APP, mobile phone-side programming) or desktop application (client-side programming). (Of course, there is more than one Java language here, and you can choose other languages. 3. Data Department: knowledge in the fields of linear algebra, calculus, Python language (including data analysis framework and commonly used AI framework) and artificial intelligence. How to start. First of all, we need to understand the most important point, that is, to start, computers need to be operated to be familiar and skilled, so if you have the idea of "I want to learn to use computers", then the most important thing for you at this moment is to start this action. Maybe we will have some doubts, such as how to start, how to do, how to learn, and so on. No matter what doubts you have, please put them down for the time being, because if you decide to learn computer, these will be obstacles for you to continue. It is apt to put a sentence here: since you have chosen a distant place, you only care about hardships, no matter where the road is. It is most important to start this matter, and it is most important to act immediately. What information to choose. I recommend learning through written materials, because when we encounter problems, we go to Baidu or Google or something else, and all we get are fragmentary graphic materials and few videos, but it is also a good choice for newcomers. Obviously, you can't choose videos that are too old, such as zero years old and xp system. Definitely inappropriate, at least win7 or win8. Although the video of win 10 is better, whether there is a video of win 10 is a problem, so the videos of other windows are also of great reference value. Through them, we can fully grasp the basic operation of the computer. What's the difference between win 10 and win8? For beginners, there are three main parts: start menu, taskbar and settings. The resource manager of the system is not much different from win7, and so is the control panel, including the registry. The task manager can basically use win7 and win 10, not to mention the application software such as office and browser. So you can use the introductory video of win7 and higher systems.
