I have been engaged in the computer sales industry for several years. In the process, I also involved computer maintenance, enterprise maintenance and network infrastructure. The more time goes by, the more I find that my professional knowledge is not enough. After all, I am not a computer major. After graduating from a trade major, I joined the pseudo-IT industry (the reason why I say the pseudo-IT industry is that people who are now engaged in computer sales, Eighty percent of the people are even at the entry-level level) and continue to accumulate in the process to improve their professional knowledge level. Now that technology is developing so fast, more and more knowledge is needed in the process of sales and maintenance. I urge myself to learn a little more knowledge to recharge, even if I can't meet professional standards, at least I must not ask three questions.
The first thing I want to learn now is the operating system, because this is the one I have the most contact with and the most applications, followed by network construction and network security knowledge, because now I am doing equipment room facilities maintenance for enterprises, at the current level, it is You can only do a database data backup, if there are difficulties, you can't solve it yourself.
