Test analysis: this paragraph uses five semicolons and has six levels, but it does not mean that it has six characteristics. Through analysis, it is known that each clause involves time, and time is extremely short relative to quantity. So one of the characteristics is fast processing speed. Each clause has a large number relative to a short time, which reflects the large amount of information to be processed, which is the second feature. It should also be noted that different clauses deal with different things, such as photos, videos, information, applications, emails and so on. So the third feature is that there are many data types.
