Introduction
NIC ASIA Bank was established as Nepal Industrial and Commercial Bank on 21 July 1998.
It was retitled NIC ASIA Bank on 30 June 2013 after it resolved with Bank of Asian Nepal's
first combination of two commercial banks in its Nepal history. After the union, NIC ASIA
was acclaimed as “Bank of the Year 2013-Nepal” by The Banker, Financial Times, UK. NIC
ASIA BANK is one of the largest banks in Nepal and its working more than 300 branches
within Nepal with a good number of services and IT infrastructure. Here for the past few
years, I have been working as a network or IT officer and along with it branch which is
opening in Kathmandu with its Depart name and I need to create design and deploy the
protocols and network types infrastructure along with standards and I also need to configure
several topologies physically and logically. In this part, I am going to configure the server
selection and bandwidth deployment with a selection of a good number of technology and
topology.
Discuss the benefits and constraints of different network types and standards
What is networking? A computer network is a consolidation of computers in sync through
networked devices and media in a structured aspect and these computers communicate to
communicate with each other. About going along with the report it will confession of
networking principles, protocols along with devices, including benefits and constraints of
networked explanation in the network, the impact of network topology, communication and
bandwidth qualification, the capability of networking systems, operating principles of
networking devices and server types and networking software. (What Is Networking? (2021))
Network protocol:-
Network protocols are official standards and policies compromised of rules measures and
formats that describe communication between two or more devices over a network. Network
protocols govern the end-to-end process of appropriate secure and managed data or network
communication. (What Is Networking protocol? (2021))
Network type
There are mainly 3 types of computer networks:
LAN (Local Area Network):
The LAN which is also known as the private network in the building is an area that is several
km in size. They are mainly used to connect with servers and workstations in offices and
factories to share resources and exchange information. I have also used the LANs which are
mainly used for resource sharing expensive hardware like printers and CD/ROM where one
can share by mainly users when they are attached to a network through LAN. (What Is LAN?
(2021))

WAN (Wide Area Network):
It is additionally alluded to as a “Wide Area Network”, which is utilized in huge geographic
areas commonly for entire nation feeding on some hundred to a few thousand kilometers.
These things conclude a set of machines expected at running programs for clients who are
running it. These machines are frequently alluded to as has or are called servers, conclusion
frameworks. Primary machines are associated with subnets or communication subnets. The
mission of a subnet is to convey messages from one server to another. (What Is WAN?
(2021))

MAN (Metropolitan Area Network):-
A metropolitan area network (MAN) is a computer network that connects computers within a
metropolitan area, which could be a single large city, multiple cities, and towns, or any given
large area with multiple buildings. A metropolitan area network (MAN) is larger than a local
area network (LAN) but smaller than a wide area network (WAN) (WAN). MANs do not
have to be in urban areas; the term "metropolitan" implies the size of the network, not the
demographics of the area that it serves. (What Is MAN? (2021))

2 more networks types are widely used which are:-
Peer to peer networks:-
In a peer-to-peer network, computers are connected over the internet and files can be
transferred directly between them without the need for a central server. Each computer in a
peer-to-peer network serves as both a server and a client. To join a peer-to-peer network, all
you need is an internet connection and software like LimeWire, Bear share, or others. You
can search for files on other people's computers once you've linked to a peer-to-peer network.
(What Is Peer-to-peer networks? (2021))
Advantages of peer to peer network:-
 There is no need for an operating system
 Doesn’t need an expensive server because individual workstations are used to
access files.
 Installation and setup are quite painless because of the building support in the
modern operating system.
 Much easier to set up doesn’t need specialist knowledge.
The disadvantage of paper to peer networks:-
 Since each computer might be accessed by others it can slow down the
performance of the user.
 Files and folders cannot be centrally backed up.


Client-server networks:-
This is a computer network that is centralized with a powerful computer (called the server) is
a hub to which many less powerful personal computers or workstations (called clients) are
connected the clients run programs and access data which are stored on the server. (What Is
Client-server networks? (2021))
Advantages of client-server network:-
 All files are stored in a central location
 Network peripherals are controlled centrally.
 Backups and network security are controlled centrally.
 Not limited to a small number of computers.
 The server can be accessed anywhere across numerous platforms.
Disadvantages of client-server network:-
 The server is expensive to purchase.
 If any part of the network fails a lot of disruption can occur.
 Can become very expensive due to the need of a server as well as networking
devices such as hubs, router, and switches.

Cloud server:-
This is a server that is build hosted and delivered through a cloud computing platform over
the internet a cloud server can also be called a virtual server. There are two types of cloud
servers logical and physical. Logical is when it is delivered through server virtualization, the
physical is logically distributed into or more logical servers but the physical server is also
accessed through the internet. (What Is Cloud server? (2021))
Cluster server:-
These are computers that are connected and operate close to acting as a single computer. The
performance of a cluster server can match that of an expensive computer or sometimes even
resulting in supercomputer capabilities. Clustering is the connectivity of two or more servers
in orderto work like one. (What Is Cluster server? (2021))
Centralized server:-
This server which acts as the agent for all communications this server stores both
communications and user account information. (What Is Centralized server? (2021))
Virtualized server:-
Server virtualization is a virtualization method that includes dividing a physical server into a
number several virtual servers with the help of virtualization software. In server
virtualization, each virtual server runs multiple operating system instances at the same time.
(What Is Virtualized server? (2021))
Network standards:-
Network standards describe the rules for data communications that are needed for the
interoperability of networking technologies and processes. Standards help in creating and
maintaining an open market and allow different vendors to compete on the basis of the
quality of their products while being compatible with current market products. (What Is
Network standards? (2021))
