Hello James!
Good post in regards to distinguishing the TCP and Ip and the fact that you were able to highlight the functionality between the two. I’ve been keen into learning Linux and just as i thought, both TCP/IP are native in the kernel. Also, they are heavily used in servers, cloud infrastructure, routers an even firewalls. In essence, any device that connects to a network today uses them and its practically supported by every OS. Also, great reference provided as it was an interesting topic to read.
