INTRODUCTION
With technological advancement there has been major improvement in wireless technology.
Now, communicate is easily been done in wide area. The technology is expanded in all over the
world. Many new technologies have emerged in network such as intranet, WAN, etc. Besides
this, businesses and people are easily able to connect with each other. Likewise, technological
era is transforming entire world (Johannisson, 2017). In today’s world telecommunication has
become flexible. The geographical boundaries are crossed and internet is expanded. By use of
network data sharing and communication process is eased. The data is easily transmitted over a
network without any data loss. In addition, standard protocols are followed in it.
This assignment will discuss benefit and constraints of different network types. Also, it
will explain impact of network topology. In addition to it, discussion will be on principles of
networking devices and servers. Moreover, it will be described about inter dependence of
workstation hardware and software.
P1 Discuss benefit and constraint of different network types
A network is a connection of different types of computers, servers, devices, etc. which
share data and information with each other. The data and information is transferred from one
computer to another. A network can be centralized or decentralised.
PAN- it is referred as personal area network usually used for personal purpose. Its range is only
10 metres. The network is mostly wireless.
Advantage (pics)
It is very cost effective network and easy to use
many devices can bе connected at one time
it is a secured network as devices are authorized before data is shared.
Disadvantage
the range is very low so it limits data sharing.
The speed of data transfer is slow.

LAN- It is known as local area network. It connects several computer within a range. They are
created in buildings, etc. or any place (Raleigh, and et.al., 2016).

(Figure 2 LAN, Gokhan Kosem, 2018)
Advantage
It helps in sharing of resources easily as it saves time.
It is easy to install LAN as cost is cheap.
The resources are easily shared such as printer, server, etc.
Disadvantage
The distance is only limited to specific area.
Sometime high cost is required for setting LAN.
MAN- It connects different users within a geographical area which can be either two cities or
states. Many LAN’s can be connected for a MAN. Fibre optical cables are been used in this type
for high speed data. (Keeble, and Wilkinson, 2017)
Advantages
5

It uses fibre optics through which files and data are quickly transferred.
Multiple user can share network easily with same internet speed
It is less expensive to attach MAN with WAN
Disadvantage
MAN is difficult to manage as it is complex.
It is difficult task to set up MAN.
WAN- This network is largest one as it connects network with network. An example can be
taken of world where network is established. It is a collection of various LANs connected
together. The connection is established with router in LAN and WAN.
Advantage
It increases bandwidth of network through which data is transferred easily.
The installation cost is cut as there is high rise in profits.
Disadvantage
The set up cost is high where advance software and server are required.
Maintaining a WAN is complex task as it requires continuous monitoring.

Peer to peer network- It is a type of network where computers are connected to each other via
internet. The data is directly shared within network. Also, there is no server installed in it. In this
system act as both client and server. (Farhady, Lee, and Nakao, 2015)
Advantage
it does not require any network operating system
it is easier to set up as not specific knowledge is required.
The failure of one system does not impact on entire network
no server is needed as system can easily access files.
Disadvantage
the files are not backed up as there is no server used in it.
The performance of network is slow as computer can be accessed by others,
virus attack are common in peer to peer to network as security measures are weak.

Client server – This is a model where several computers are connected to a centralized server.
They act as a client and server controls resources and provide services to computers in network.
7

The client communicate with one another through server. Moreover, data and info is transferred
through server. However, server receives and accept request of client in network.
Advantage
Use of server improves entire network performance
Resources are easily shared between devices as whole network is centralized.
Disadvantage
The client processing request takes time as process follows through server.
Its maintenance cost is too high because it requires network expert to maintain and control
network. (Kuss, and Griffiths, 2017)

Network standards:
Definition:- they refer as networking techniques and standards through which communication is
done. It consists of rules and networking devices
OSI model – It stands for open system interconnection model developed by ISO in 1974. There
are seven layers in conceptual model that is stated below :- (Layers of OSI model, 2015).
