3. What is a NOS?
A Network Operating System
(NOS) is a software program
that controls other software and
hardware running on a network.
It also allows multiple
computers, known as network
computers, to communicate with
one central hub and each other
to share resources, run
applications, and send
messages. Such a system can
consist of a wireless network,
Local Area Network (LAN), or
even two or three computer
networks connected together.
Administrators running these
networks typically have training
in different network operating
systems.

5. SUPPORT
The first characteristic of network operating systems is
the support component. Network operating systems
provide support for the multiple processors, applications,
and hardware devices that make up a network. The
systems support the users accessing the network as well
as process requests for specific documents and usage of
hardware. NOSs also provide protocol requests from
users, including Transmission Control Protocol/Internet
Protocol (TCP/IP) and other protocols.

6. Controls Support
The second characteristic of network
operating systems is the security
component. NOSs manage the
authorization and authentication of
users, computer workstations, and
other devices accessing a network. If
an intruder tries to access a network,
the NOS blocks the unauthorized
user/computer and logs the intrusion
attempt within its log files. The NOS
also manages software and
hardware installations to keep users
from installing unauthorized software
and devices.

7. Setup
The third characteristic of
network operating systems is the
user setup component. Network
operating systems create user
accounts and manage the users
logging into and out of the
network. The systems also
manage what file and directory
services a specific user has
access to, users accessing the
network remotely, and how the
network's graphical interface
looks to specific users.

8. Printing and File Services
The fourth characteristic of network operating systems is
the printing and file services component. Like other
operating systems, network operating systems manage all
printing, storage, backup, and duplication services for
computers and users accessing a network. The systems
also control access to the Internet, local-area (LAN) and
wide-area networks (WAN), port routing, and internal web
services known as Intranet. An NOS filters documents and
files through the printing/file services immediately. More
than one user can send documents and files through the
network for printing, backing up, or other types of
processing.

9. EMAIL SERVICES
The Fifth and final
characteristic of network
operating systems is the email
component. An NOS manages
electronic mail, also known as
email, for the entire network,
including users accessing the
NOS remotely and from the
Internet. The NOS blocks
SPAM and other problematic
emails and sends/receives
email, as well as lets users
create additional email
accounts.
