1. There is nothing to say about theoretical knowledge and composition principles, so extract it from the textbook. Just indicate the detailed source at the end of the article.

2. With regard to comparative analysis, I suggest you collect more information in this respect online (go to the quotation area of some big professional websites, such as Zhongguancun Online, PConline, etc. ), and it is best to sort out the market trends for more than five months, and then classify and compare them in tabular form and chart form, and then draw a conclusion according to the chart to make a comparative study of the hardware markets among cities.

3. After comparative study, the language of the current market situation and the future market situation of computer hardware equipment has come out.

4. Pay attention to the paper format and write as required.

The paper is actually very simple and needs patience to write. Never copy.
