What are the two types of network operating systems?
There are two basic types of network operating systems, the peer-to-peer NOS and the client/server NOS: Peer-to-peer network operating systems allow users to share network resources saved in a common, accessible network location.
What are the advantages of network operating system?
Advantages of Network Operating System:
- Highly stable centralized servers.
- Security concerns are handled through servers.

How does operating system handle input and output?
This is called memory management. input/output devices: The OS must ensure that the devices are used correctly and fairly by the executing programs. … The OS also provides the interrupt-handling programs that the processor executes when an input/output device signals an interrupt.

Process Hierarchy
When a process creates another process, then the parent and the child processes tend to associate with each other in certain ways and further. The child process can also create other processes if required. This parent-child like structure of processes form a hierarchy, called Process Hierarchy.

Where is distributed operating system used?
Distributed Operating System is one of the important type of operating system. Multiple central processors are used by Distributed systems to serve multiple real-time applications and multiple users. Accordingly, Data processing jobs are distributed among the processors.
What is peer to peer NOS?
Peer-to-Peer Network Connection
In peer-to-peer (P2P) networking, a group of computers are linked together with equal permissions and responsibilities for processing data. Unlike traditional client-server networking, no devices in a P2P network are designated solely to serve or to receive data.
