Detailed description of nc parameters in Linux

Surely those who are familiar with Server programming in linux must have used a very short and concise command nc that is powerful and well known as a Swiss Army knife. We can use nc to build an output server or use it as a client, and we can use its various parameters to precisely control transmission and connection details, so that it becomes exceptionally powerful.
