Data can be text, image, audio, and more. Many times we also need to send data over the internet to a specific URL. For doing these tasks, you have to write multiple lines of code and the process will be very complex when we do not use any library for this.

So that he can get the exact idea that the problem is with my network, not with the software or application. Otherwise, he may assume that the application is not good and it will create a negative impact on the users of the application.
