Introduction
In the present world, communication has experienced tremendous growth in all of its angles
dimension. The whole world has been reduced to a small village as a result of impressed
technology. Area of networks has been part of the drive of all these changes. In this task
assignment, I will be looking at network concepts its broad scope. These will include
network roles, advantages disadvantages, network operating system, a comparison of
network operating system, installation of network operating system, network proposal for a
scenario case, and network management.
Networking Concepts
Task 1: Network Roles
Computer networking refers to the interlinking of computing devices form a network. For
success of every organization, information and communication are important aspects that
eliminate isolation of resources computing resources. Isolation of resources results to
under-utilization of resources. To overcome the isolation problem, computer networking is
the saviour. Computer networks merges the isolated areas and resources. The convergence
of resources does away with unnecessary resources required to process and store data.
Computer networks for sure provides us with borderless communications (Kizza, 2017).
Advantages
Computer networks will permit a client to have access of remote databases and programs.
This eliminates the unnecessary movements amongst employees of an organization. Thus,
improved productivity. Besides the mentioned advantage of computer networking, the
following are other core benefits of computer networks for an organization:
i. Reduced cost by sharing of resources e.g. a shared printer over the network can
serve more than one employee.
ii. High consistency due increased sources of supply
iii. High flexibility of possibility connection of devices from the business partners
iv. Files can be shared with ease
v. Networks improves communication structure of an organisation (Al-Bahadili,
2012 )

Disadvantages
However, computer networks have also disadvantages. This include but are not limited to:
i. Purchasing of computer networking infrastructure is expensive
ii. Virus are threats to organizations and can be spread over the networks.
iii. Management of huge networks can be a complication which require training and
network manager has to be employed.
iv. Dangers of hacking are lurking outside there (Johnson, 2013).
Benefit of installation of network to a school college /business
Computer network is really necessary for a college and businesses. For a college
environment, tutors will be able to share learning materials over the network. Additionally,
communications are made to college students via emails on the network. Distant learning is
one of the learning dimensions which has been embraced by many colleges. Students are
able take their classes while they are at their places of work. This is only enabled by use of
networks.
For the business environment, all of the business processes have come to depend on
Information technology. Indeed, information technology drives the business today.
Computer networks is a primary component of information technology. I imagine of a
business environment which has no elements then I imagine how do they communicate to
their customers, how do they source information, how do they advertise their products.
We realize that today for every business activity to survive, networking has to be included.
Task 2: Network Operating System
Purpose and function of a (NOS) network operating system.
A networking operating system purposed to support personal computer, workstations and
terminals that are connected to a network’s LAN. The network operating system offers
database and file sharing, printer sharing, application sharing and capability to manage
network (Rajiv, 2016).
Comparison of Network Operating System
Computing environments consider NOS as multipurpose systems that perform a number of
activities at certain time. However, they are only talked of in terms of networking rather
than other activities they perform. Sample of these operating Systems include but are not

NOS installation
Installation of Network Operating system takes the following steps:
i. Insert a bootable USB flash or CD in USB port or CD-ROM respectively.
ii. Let the computer reboot
iii. At the beginning of the boot process, continuous tap the appropriate functional
key that lets you choose boot options. Most of the time, F12 allows you to enter
into boot mode options.
iv. Once boot selection has been done, press F10 to save changes and let the OS
begin the Installation.
v. Select language of your choice.
vi. Go through the Licence agreement, click “I agree”
vii. Choose advanced installation to have an express installation
viii. Proceed with Next, Next Next steps till you let installation continue on its own.
ix. Once an installation has been finished, the NOS is ready for customization and
use (Haldar, 2016 ).
Task 3: Network Proposal
Network proposal for a gaming café’
A gaming café’ with 10 users is a small factor network environment. The areas to consider
for the proposal are: hardware requirements, network requirements, and software
The requirements are tabulated as below:
Item Quantity Justification
HP ProLiant Server 1 Server will be required to
host services such shared
game application, DHCP,

Network test Plan
To check the functionality of the implemented network, a test plan has to be done. For our
implemented network, the test plan we will perform tests on performance, reliability, ease
of use and usability of the network
Task 4: Network management
Network management denotes to the observation and controllability of the network
infrastructure. For our gaming’ network scenario the following will be Area of
management key factors:
i. Cable management: the cabling environment should be well managed to avoid
risk hazards of the clients falling due to hanging cables.
ii. Uptime: the gaming’ ought to be available 99.9999 percent all time as needed by
clients. It should be remembered that clients who come in and find the service
they expected is missing they turn away frustrated and will never come back
iii. Sitting arrangement should be put in a manner that is not tiring to clients.
iv. Privacy: user information should remain private at all times (Ding, 2016 ).

Network management guide
The network management guide will always be referred to at all times to ensure that there
is a smooth running of the gaming café network. It should good to mention that once the
installation is properly done and tests performed, very minimal of faults will take place. The
following will be our guide line:
Fault troubleshooting: this involves identification and the isolation of a problem providing a
resolution for the problem. Common faults experienced are power losses and loose power
cables. It is good to make sure power is availed. UPSes will be doing a good here.
Security: as an admin for the café’ user data will always remain private. In case of exposure,
checks should be done to measure the loss caused
User and group management: network users and their activities must be known through
user management.
All in all, below is our network management will power

Conclusion
Conclusively, it is agreeable matter that no business organization will survive in the present
market without deployment of network infrastructure. Network infrastructure has become
an essential need for every organization for its services such communication, resource
sharing and interconnection of computers are services that if missed by an organization, the
organization will be down on its knees due to increased expenditure.
