Explanation:
An operating system which was developed in the 1950s, is a software which acts as an intermediary between the computer hardware and end users.
The functions of an Operating System are; Memory, Device, Process, File, Secondary-Storage and Input/Output management.
The networking component of the computer's operating system ensures that a group of processors don't share memory, clock and hardware devices, instead the processors communicate with each other through the network.
Basically, the network Operating System (OS) runs on a server and provides the capability to serve to manage groups, user, application or program, data, security and any other networking functions.
