Introduction
Information Technology (IT) infrastructure refers to combination of set of software,
hardware, facilities, networks, etc. that are being used for development, testing, delivering,
monitoring, controlling as well as supporting IT services (Ajamieh and et. al., 2016). It enables
organisation for delivering IT solutions as well as services to their customers, partners or
employees. This report is based on Nuix Pty Ltd, that is a Australian technology organisation
that is responsible for producing software platform for analysing, searching, indexing as well as
extraction of knowledge from unstructured information or data. This report comprises of services
organisation provided and ways in which it has been utilised by department. Along with this,
network devices are identified that can be used for attainment of activities. Moreover, application
software needed for data communication has been specified and at last seven layers of OSI
model has been explicated.
1. Introduction to services rendered by Nuix Pty Ltd and ways in which each department makes
use of information technology.
Nuix Pty Ltd is Proprietary company which deals within software industry and was
founded in 2000. They develop innovative software which empowers organisation for simply as
well as quickly find out the truth from data within digital world. They are responsible for digital
investigation, eDiscovery, information governance and security & intelligence solutions with
respect to Nuix Engine. This aggregates fault tolerance, processing technologies and load
balancing for rendering insights from larger volumes of structured, semi-structured and
unstructured data. Nuix Insight Adaptive Security is responsible for integration of cybersecurity
threat prevention, their detection, response to them, remediation as well as their deception. They
assist organisations to deal the challenges associated with investigation, litigation, compliance,
risk, security and governance.
This organisation is entirely dependent on information technology for delivering their
services as this deals within software industry. They need to possess adequate knowledge with
respect to advancements that have been made within technology so that they can accordingly
alter their services and make use of those technologies while rendering their services (Gardner,
Boyer and Gray, 2015). There are different departments within Nuix Pty Ltd email is the
1

common method that is being used for carrying out communication. For looking into
information, technology is being used. For an instance a message is sent by an intruder or a mail
in which there is a URL (Uniform Resource Locator). The reason behind this can be to have
access to their systems or for any reason. The employees of organisation will make use of
technology for finding out the person behind this. In similar manner, all employees of Nuix Pty
Ltd will look forward for certain information or build a software and in this they will be making
use of technology.
2. Identification of network devices needed for attainment of everyday activities along with their
functions.
The components that are being used for connecting computers or any other electronic
devices through which resources or files such as fax machines or printers can be shared are
referred to network devices. Nuix Pty Ltd is making use of switch, routers and hub for carrying
out their day to day operations.
Switch: They are aware of addresses that are linked with their ports as well are
responsible for forwarding every incoming data to the precise port. Normally, switch acts as a
base fro forwarding decisions with respect to guidelines that is present on the headers within
TCP/IP protocols. They are capable of inspection of data frames like the way in which they have
been received as well as source are determined so that they can be transfer into an appropriate
manner (Dahiya and Mathew, 2016).
Hubs: They denotes connectivity devices in which network cables are attached for
forming a network segment. They do not filter data but usually retransmit the incoming frames or
data packets to all the parts. At present most of the organisations as well as Nuix Pty Ltd make
use of central hub in which computers on network are connected. This allows several devices to
connect as it comprises of diverse Ethernet ports that can be used for connecting network
devices.
Routers: They are highly intelligent devices that are being used for connecting various
types of network as well as identify best part through which data can be sent. It is a virtual or
physical appliance that is responsible fro passing information among packet switched computer
networks that analyse destination of data packets and identify best way for reaching destination
as well as forward them respectively.

3. Specification of application software needed for data communication in between clients as
well as servers.
For carrying out interaction in between client and servers there needs to be hardware and
software independence. Operating system is the core that is needed as it provides interface in
between hardware as well as software. This will provide them with precise results. In addition to
this there are network systems which will be acting as major source of interaction in between
them. For an instance, if systems are not connected, then there will be delay in services as well as
resources cannot be shared in between them. This denotes that there is need of interconnection in
between systems through which performance can be improvised of all the employees and this
also enable to share exact resources and information.
4. Usage of seven layers of OSI Model to explicate the ways in which data is moved in between
layers.
Open System Interconnection (OSI) is defined as a reference model which illustrates the
way in which information from one system moves from physical medium to software application
in other system. It was given by ISO (International Organisation for Standardization) in 1984 and
is taken into consideration as a architectural model inter-computer communication. It is
responsible for dividing project or any specific task into manageable tasks (Serrano, Gallardo
and Hernantes, 2015). OSI model is used by Nuix Pty Ltd for carrying out their operations. The
seven layers with respect to this has been illustrated below:
 Physical layer: It is liable for transmitting individual bits from one node to the other and
establishes, maintains as well as deactivates physical connection. Basically, this layer
denotes electrical as well as physical representation of system. This can comprise of
radio frequency link similar to 802.11 wireless systems, cable types, voltage, layout as
well as physical requirements. Generally, they denotes the internal working for an
instance power plug is connected to switch or a system. The physical layer will provide
employee of Nuix Pty Ltd a means for transmitting web page request to default
gateway.
 Data link layer: This layer is liable to transmission of error free data frames and also
defines format of data within a network. Generally, it furnish node-to-node data transfer
in between nodes that are directly connected (Audretsch, Heger and Veith, 2015). Along
with this efficient and reliable communication is provided among different devices. Once
3

the requests have been generated from web browser then it is transmitted to network card
than this is transformed into a message that has been sent from computer to default
gateway that will be responsible for sending that request to internet. This layer will read
MAC address from data packets and for this switches are being used.
 Network layer: In this layer, functionality of router is founded that is amenable for
forwarding of packets as well as includes routing by diverse routers. It makes use of
unique address for system as well as identify whether web server is a system that is
present somewhere on internet. For reaching a web server while in an internet, IP
protocol will allow system to find out the way for reaching internet web server through
default gateway (Orzen and Bell, 2016). At this moment, system creates message
addressed to web server with IP address. ARP is used for figuring out physical MAC
address of default gateway and then data is being passed to network layer.
 Transport layer: It deals with coordination in between data transfer among host as well
as end systems. It includes all the details associated with how much data must be sent
along with at what rate it is being sent, where it goes and various others. It includes TCP
(Transmission Control Protocol) that is being formulated above IP (Internet Protocol)
normally TCP/IP protocol. In this case with respect to employees of Nuix Pty Ltd, for
carrying out communication with web server, system needs open up a TCP connection of
a web server and makes a web page request. This connection is responsible for breaking
up web page within certain manageable chunks as well as label them by which they can
be reassembled in an appropriate manner and those pieces are transported across the
exact session.
 Session layer: When two devices or servers need to communicate with one other session
must be created and this is carried out within session layer. This includes coordination,
setup as well as coordination in between applications at the end of each session. When a
request is made for a specified web page, web browser opens up a TCP connection to
web server which sends back web page as well as close the established connections. The
HTML parses to web page and within web page instructions are being written in an
HTML tags that will let browser to find out additional files that are being displayed in
the web pages like images, Flash Files, applets, etc.

 Presentation layer: This represents the area that is independent of data representation
within application layer. Generally, it represents translation of application format into
network format or vice-versa. In this layer security aspects are also taken into
consideration and that encryption along with decryption takes place. The web browser
handles presentation of web pages to the user through conversion of files into format that
can be displayed within screen of a computer. Web browser supports diverse text
formats along with scripting languages (Buckow and et. al., 2016). Within this layer,
conversion are handled through programs that are being running on a system.
 Application layer: It is the top layer that is close to end user and allows direct
interactions in between them. They can be Netscape or Internet Explorer that will render
mean for system to contact with web server as well as download several files which will
be responsible for producing single web page. Employee of Nuix Pty Ltd can make a
request for specified web page through URL or web address.
In this way OSI Layer provides a means by which an employee can enter web browser
and look for details they are looking for. Like in this case employees were within home page of
website of Nuix Pty Ltd and way in which there requests are addressed have been illustrated
above.
5. Summary
Nuix Pty Ltd renders there services within hardware industry and are associated with
technology. For furnishing there services they make use of diverse mediums which assist them to
furnish their services in an enhanced manner. OSI was given by ISO (International Organisation
for Standardization) in 1984 and is taken into consideration as a architectural model inter-
computer communication (Blockley and Godfrey,2017). It is responsible for dividing project or
any specific task into manageable tasks. This illustrates the way in which services are being
delivered by organisation and how internal processing is carried out.
