This lecture seems to require prior knowledge of C language tcp ip principles tcp ip sockets. And it would be good to study basic grammar and libraries of Python and watch it. And this is similar in difficulty to a kindergarten child solving math geometry problems for a beginner who knows nothing. Please study C language tcp ip sockets and watch it without fail. Otherwise, you will lose money. And this video is absolutely not recommended for hacking experts. Because it teaches very basic hacking tool manufacturing. And the explanation is very good, so I give it 5 stars, but I do not have in-depth knowledge of hacking tools.
