A communication cable can comprise twisted pairs of electrical conductors for transmitting electrical signals, such as for digital communication or data transmission. The method is performed by a processor monitoring the communications session. The solution redeems the carry time-lapse for transmission data, so that the redeeming precision can reach multiple seconds, thus improving synchro precision of the data in an effective manner. The paper is supported by the support plates, and is dropped downward and stacked. The method comprises: obtaining a designated query input on a web page; matching the designated query with queries in a query candidate set including queries having a tendency of carrying an image; and when a query in the query candidate set matches the designated query, outputting a corresponding image on the web page according to the designated query.
