Recently I am studying socket TCP/IP programming tutorial in which I learnt how to do stream , raw data and all protocols such as ICMP, TCP etc...for sending and receiving in C/C++ programming.
Just want to know,. After the socket programming, the programmer is nothing to do at this position
and they have no more to learn since NIC will handle this or do the follow-up for the request, Right ?
All request or information from the socket C/C++ programming will be handled by our computer network interface cad(NIC) by hardware program, and there is NO more networking programming after socket programming ?
And all firewall setting or configuration is handled by window system for block sites and that is NOT handled by NIC card, right ?
Hope you understand my questions.
