Network data transmission is nothing more than http protocol, which mainly includes two forms: post get. Whether this kind of learning is video, picture, text or voice. Are inseparable from data transmission, saying that data transmission must be inseparable from hypertext transfer protocol. Your learning process is nothing more than the process of communicating with the server. This communication conforms to the protocol and can be simulated. This is not a loophole.
Is there any hang-up software? There must be! This kind of on-hook software is generally charging software, and its functional principle is analog communication protocol. Using these softwares is risky. First, many softwares are paid softwares. After a lot of software is paid, the online college can't be used once it is upgraded. This kind of website is upgraded very frequently. Second, many softwares are infected with viruses. After installation, they will steal your computer information and cause your computer to be paralyzed, especially this so-called "plug-in software" is actually very rogue.
Do you want to use the on-hook software? It is recommended not to use it. This shortcoming is obvious. If you have to find an intelligent software to answer questions unattended, you'd better write one yourself, which is also very simple. I found a tutorial from a province on the Internet, which is ideal, but this model is very good and safe. You can refer to this tutorial, the address is as follows, and there is contact information in the tutorial: URL link.
