Freshmen majoring in computer science and technology offer courses similar to basic computer applications, which is to get you started without buying any books. If you want to buy it, I recommend the following three models.

Computer culture

Computer Culture is written by Parsons (USA), by Ou Jia (USA), translated by Lv Yunxiang and Foer, and published by Machinery Industry Press. The price is 56.3 yuan, which can be bought on all major book buying websites. I saw it in the school library that year, which can be said to be a classic of computer introduction.

Computer magazine

Choose a computer magazine, such as Computer Enthusiast, which mainly plays the role of popularizing science and cultivating your interest.

Computer forum

Visit some computer forums frequently to get the latest information and technology. I recommend you to visit the starting point (former rainforest Mufeng community), Shen Du, CSDN and Zhongguancun Online.
