Learning Linux tends to be about network services?

Learning Linux tends to be about network services? -- Linux general technology-Linux technology and application information. For details, refer to the following section. Linux itself is a network operating system that depends on the network, especially Ubuntu.

For me, Linux system management gives me the impression that RHCE is more direct. In recent studies and usage, I have chosen the RHEL and Fedora series. In this way, it is difficult for me to look at other releases in my own way. For RHCE, it involves user configuration, local security, and network services. For me, it is almost all, but USAH and LAH do not think so, LAH talked about more underlying issues rather than application issues. This is awesome.

The proportion of network services in Linux system management is quite large, which is true for any released server application.
