INTRODUCTION
Network is defined as connection of computers with an objective to share resources,
Process of exchanging information and data between systems is called networking technology.
Networking is defined as the structuring and making of network system by using cables and
bridges. It is used to manage network and telecommunication process of organisations. It plays
an important role in providing platform for communication purposes. It helps in connecting
people in by removing geographical limits. An important platform for networking technology is
internet.
Present report describes about benefits and constraints of various system of networking
and its types. Effect of current technology of network has been discussed in the report.
Furthermore, effective utilization of network is also explained. Role of software and hardware
elements and their applications has been illustrated. Types of servers and their selection ned in
company has been discussed. More over, inter dependence of workstation hardware with
network is also illustrated in the report.
TASK 1
1.1 Benefits of networking technologies and networking systems
According to the case study Beta communication Ltd is a telecommunication company.
The organisation was using stand alone PCs and dial up approach for their networking purposes.
Now the company is planing to build their own local are network system. Purpose of network in
the company to share their resources and information effectively (PSN .2017). There is major
role and benefits of networks in information sharing of the organisation. Some benefits of
network technology is as follows:
 Sharing of information becomes easy by making us of networking technology in
organisation.
 Networking systems makes it easy for sharing files and data remotely to different
connected computers (Brandwine and Hill, 2014).
 Use of internal connected devices like printers and copiers helps in resource sharing.
 In networking single internet link is share among PC's that helps in protecting system of
the organisation from hacking.

 Storage capacity of network connected devices gets increased.
 Communication with suppliers and consumers of the company will also improve by
using networking systems.
 Business of the organisation will become more efficient by using common database
which helps in avoiding data repetition
 Centralized network supports in less requirement of IT.
There are four types networking system which have various benefits :
 Local area network : LAN comprises a single network which is suitable for particular
physical location (Christensen, 2013). Local area network is very beneficial for sharing
resources within a building. It is very useful for Beta communication Ltd. as the
company need to share information among themselves. This networking system will also
fit in their budget as this costs low in deploying this system.
(Source: Networking types .2017. )
 Metropolitan area network : MAN is network which is used for small region. It is
generally used to give internet access in entire city. A MAN is generally used to
connected together to make a bigger network.
Advantage and disadvantages of metropolitan are network :
It cover wider area so it become easy to provide conceptions.
◦ It is very useful for libraries and airports.
◦ MAN can operate only when a PC can compete.

 Wide area network : WAN is used to connect large area like whole country of region. It
contains various small networks like ;local and metropolitan area networks.
Advantages and disadvantages of WAN
 WAN contains centralized IT structure due to which it eliminates the requirement of
buying servers.
 Privacy level of the business information get increases using WAN.
 It cost very high to setup WAN's.
 Issue of maintenance is also there with WAN's Security breach problem is also with wide are networks.
 Peer based network systems : in peer based network system two or more personal
computers are linked to share resources and information. Single universal bus is used to
connect PC's to transfer files. It can be used by Beta communication Ltd.
Advantages: It is easy to install per based networking systems. P2P is reliable networks
systems. Full time administrator is not required in this.
Disadvantage: In this system its becomes difficult to determine who is accessing the network.
Data backup is also difficult in this systems.
 Client server based systems : It is made for end user who are termed as clients. These
clients can access information like files, documents and videos form the central computer
device which is called server (Da, He and Li, S., 2014). Cloud and clusters : In cloud computing file and data is saved on cloud system rather
than hard drive of computer. In clustering method two computers are linked in away so
that they can represent a single computer. It help in parallel processing. It is also
beneficial for the organisation.
Networking topologies: Networking topologies is an appropriate arrangement of networks I
order to connect different nodes. These are ring topology, start topology , mesh topology and bus
topology. In star topology nodes are connected in structure like star.
Ring topologies

In ring topology In ring topology nodes of network are connected as ring. Each PC ios
connected to another PC in this topology. Various repeaters are used in this so th one can send
data to 100 node at one time.
Star topology
In this topology computers are connected to a hub by using cables. This hub is called
central node. Each node contains its own dedicated connection to hub. It role is to act like
repeater.
Bus topology
In this topology computers are connected through single cable in sequence. This topology
can transmit data packets in single direction only. Each device is connected with one cable. Cost
requires to install this is very low.

Requirements for the organisation to install network
Beta communication Ltd. requires to analyse its communication methods, reporting hierarchy,
structure of the organisation. Local administrative rules and policies are need to be considered.
Further company will require Ethernet cables, modem, routers, switches, hubs repeaters etc to
install a network. Type of files and applications that need to be run on network should be
identified. Requirements for organisation to install a network are as follows:
Company should consider purpose of the network .Organisation requires networking variables
and maintenance of network. Company needs to understand physical networks and information
of active directory. Network structure of the area need to understand.
1.2 Impact of current network technologies
There is a huge impact of current network technologies on Beta communication Ltd.
Current network technologies an there effects are as follows:
File transfer protocol (FTP)
This protocol is a standard protocol which is used to transfer information and data form
one server to another one. It is a popular protocol which for upload and download process of
flies. This protocol uses TCP/ IP protocol for enabling transfer of data. In this client server
model is used to which is protected with SSL/ TLS. This enables file sharing through remote
computers. Data is transferred deficiently in this protocol. It provides authentication to user by
simple sign in protocol (Gubbi and et.al, 2013). Username and password are required by client
for authentication process. The FTP totally depends on client and server. It works in two mode
which are passive and active. In the active state client start initiating a session by sending a
command. This command is received by server and after that it make connection to client for

enabling data transfer. This protocol can be used by Beta communication Ltd. for efficient and
secure transfer of data.
Simple mail transfer protocol (SMTP)
It is an standard protocol which is used for email transferring services. This protocol also
uses TCP/IP protocol to enable file transferring. It is used to upload mail directly on networks.
Simple mail transfer protocol use POP 3 service. It is an application layer model which helps in
enabling transmission of emails over internet. It is popular model which is used for
communication via email. In SMTP there are four types of keys which is use between client and
server. These keys are Mail user agent, mail submission agent , mail transfer agent and agent for
mail delivery.
Hyper text transfer protocol (HTTP)
It is a protocol in which particular set of rules are defined for transferring files. This
protocol support in transferring files such as sound, text, video and various type of multimedia
files. File are transferred on the World Wide Web. Users use HTTP whenever they open web
browser on their computers. It is an application protocol whose functioning totally depends on
TCP/IP suite. Hypertext is used in this protocol which gives references to various files which are
result of user request on browser (Istepanian, Laxminarayan and Pattichis, 2014).
IPV4
IPV4 is a fourth version of internet protocol. It is used widely data communication on
various type of networks (Jain and Paul, 2013). It is connection less protocol which is sued in
Ethernet services. Logical connection is provided by IPV4 for device identification. This
protocol is configured using no automatic and automatic configurations. These configurations
depends on the type of network. This protocol do not provides guarantee of duplicate data.
IPV6
This protocol is 6th version of internet protocol. It is used to fulfil the requirements of
more addresses for internet (Kim, and et.al 2014). This protocol overcomes the bugs of previous
version i.e. IPV4. This protocol do not requires manual configuration because it is an auto
configured protocol. It provides better masticasting. It has inbuilt authentication support. Header
format is simpler that that of IPV4. Thus internet protocol should be used while designing
network system for beta communication Ltd.
