Languages that computer majors should know (please specify)

General study C, vc++, java, jsp, vbs.

Database language sql.

Now many people study C and vc++.

Many people say they don't know where to learn. If you're just starting out, don't always think about getting there in one step, and don't think that invasion is the highest realm! Don't think that you can become a master by relying on some hacker software, some vulnerability information and others foolishly teaching you to invade. In that case, you will eventually find yourself with nothing. Maybe many people only know how to attack, but they don't know how to protect themselves. For example, you successfully exploited a CGI vulnerability according to some hacker tutorials, and the invasion was successful, but do you know why it became a CGI vulnerability? Will you judge what loopholes CGI may have or what loopholes it may have according to its working state? A series of problems is to have a series of basic knowledge.

Want to learn, ok! Let's start with an ordinary user!

At least, you have to know the basic composition of hardware. What is a motherboard? What's the motherboard for? What is CPU? How does CPU work? What is memory? What is hardware, etc. Operating system, WINDOWS98/WINDOWS2000/LINUX, are you familiar with these systems? Commonly used software, if you can't even use WIZIP, practice it yourself first. What about the internet? What is the Internet for? Have all the problems encountered been solved in normal operation? Wait a minute. . .

If you understand all the above, you should move on, and you can learn something deeper.

Then start with TCP/IP network protocol, which is very useful for the network. Learn to use a series of network commands, and then learn how ports work. Learn the configuration of the server when you are free. How many kinds of servers are there and what are they used for? How does it configure and work? Wait a minute. . .

I understand all the above. You can easily invade a website by referring to some materials. If you think you are good enough, go further! Learn programming.

What is programming? What is this for? What's the use of learning it? What are the benefits of learning it? What language should I learn? Book for yourself and study hard!

If you already have a programming strength, but you know all kinds of programming languages and are familiar with the field, then I think you are already a master for me, and I want to learn from you.

However, in fact, if you want to improve your technology, you have to study by yourself, read more books and look up more information. No one has invaded some websites without knowing the port. Many experts are self-taught. How can you make progress if you don't even want to work hard? Read more, write more and practice more, and you will soon become an expert. Believe in yourself.

Practicing and thinking by yourself is definitely better than going to the forum to ask questions whenever you encounter problems. In fact, there is a lot of information you need in the forum, but you don't want to find it yourself. If you read all the articles on the forum, you are not an expert. If you want to study, have a snack! In the process of learning, if you are sure you can't handle it, you can ask questions. I think everyone will help you very enthusiastically.

May everyone make progress together!
