Olson, C 2014, online, Getting started with storage. Understanding SAN vs NAS vs DAS,
viewed 22/01/2018, <https://vanillavideo.com/blog/2014/started-storage-understanding-san-
nas-das>.
Summary:
Storage is one of the main issues from the time when the technology of
computing, wired and wireless communication came to the market. When the
topic of storage is discussed, it requires a long time to think which include
many factors to be considered such as time, cost and more. I have selected
this resource as it discusses both the storage technology in every possible
manner. Directly Attached Storage (DAS) is that storage which has multiple
disks and this array of disks works together in the same way while the
Network Attached Storage is that storage found on the file server rather than
number or size of the disk and it acts like a device which shares the files with
the help of network. With the help of this resource, the communication of
wired and wireless computing in addition to storage technologies has a
tremendous hike in the last past decade and that is why it is highly relevant to
the task.
For DAS, I found that it can be used as super desktop having high speed as an
application in the market. The set-up of the DAS is simple and cheaper. It
does not require network and IP addresses. It performs faster and shows better
latency. However, beyond the positive features, the author also explains the
negative side which includes its dedication towards the single device, does not
manage the network and always requires special hardware connection. For
2

NAS, the author explains that it has a good feature in providing the large
space for the storage and is economic. I also found that it provides better
redundancy for the mass number of users. It provides better security by
applying restrictions such as user permissions, password protected document,
and folders. Instead of these features, the author also explains that it requires
IP address and network space for working and in addition to it shows less
latency and shares the highest data which is possible to be done at the speed
of the given network.

Summary:
In the resource, authors explain about real time operating system (RTOS) and its
application in different industrial and academic environment where the
quantitative and qualitative analysis of RTOS has been. The analysis is done on
the Windows CE, QNX Neutrino, Vx Works, Linux and more. The resource also
contains the evaluations of several response times and their results. I have selected
this resource as it is highly relevant to the task as explains all the capabilities of the
Real-time operating system for a specified time constraint. This operating is used
for many purposes such has it has good feature of controlling the functions and
author also explains about this with help of example of manufacturing vehicle
company. RTOS is also used in different areas of the world as it is a multi-tasking
OS and has its dependency on the logical correctness and delivery time of the
application. The algorithm used is round robin algorithm and scheduling method
used is pre-empty priority method. Authors also added that it has great advantage
that it does not require much space. The objective of this paper is to analyze the
different OS that can be used for the medical device applications. This paper
explains the need of a professional and non-technical group and also provides the
4

comparison for different types of RTOS.
As the selection criteria depends upon four features of the RTOS and they are
functionality, performance, price and advanced features. When the real time
operating systems are considered of the health sector these factors are analyzed.
The supervisors at the health sector take advantages of patient monitoring with the
help of the RTOS and provide home facilities. This decreases the cost of any extra
charges that may be related to the doctors and hospital stays. The results of the
provided facilities can also be enhanced with the help of RTOS. The management
of the health security can be achieved and able access the real time data. The uses
of such type of system help in decreasing the probability of getting error in the
information system of the health sector (Patel, 2017).

Summary:
Mobile cloud computing is getting popular different sector because of its
important features mainly associated to the availability of the space and speed.
The innovations that had taken place in the mobile computing have led to its
highest points in the market and also provide additional possibilities of
changes and creative with multiple applications. Author clarifies that this
technology makes the machine system to work in an extraordinary
environment. This advanced technology has changed the method of handling
the information and provides the use of different types of servers. The author
also added that the idea was firstly given by the John MC-Cathy as this
technology will be a future utilization of the computers in terms of open
source. This technology helps in providing facilities to the IT division which
consist of internet benefits as much as possible. It has ability of easy access
through distributed computing methodologies for the remote areas. it is highly
6

relevant to the task as it explains all the required essentials of the acceptance
by the organizations or by individuals.
As the research on security issues has been done, there are several risk that
came to know. The security and the privacy issues for the financial sector
when mobile cloud computing used includes user access authentication,
conformance of the regulations, available memory, data separation, backup,
and investigation. Financial sector uses the personal information of the
customer for providing the facilities. Therefore both security and privacy
issues occurs in the form of data, privacy and infected application issues.
When data is shared to the cloud, anyone can access it and modify it which
can be harmful for many of the organizations in terms of perspective of their
customers. Stealing of the data from the cloud storage is one of the major
issues appearing now-a-days in addition to asking for ransom. Loss of data is
also the major issue during shut down of the large servers in case not regular
updates of the recovery at the financial institutions (Shahzad and Hussain,
2013).

Week 4
Task TCP/IP is consists of communication protocols used to transfer packets
between computer hosts within the network. In TCP/IP, the transport layer is
responsible for providing the application layer with session and datagram
communication services. Discuss the common standards at the transport layer.
Summary Title and Reference:
Hunt, C 2010, TCP/IP Network Administration. 3rd ed. Sebastopol: O'Reilly Media, Inc.
Summary:
This resource explains all the communications protocols related to the TCP/IP
which is used for transfer of the information between different devices in the
specified network. This is especially used in the homogeneous networks and
the rules are designed in such a way that it provides strengths to both
operating systems and hardware architecture. Author also added that the
protocols associated to the TCI/IP are available to everyone and can be
changed by the consensus. I choose this resource as it is highly relevant to the
task as it explains all the protocols that help in the exchange of the
information. The protocol architecture of the TCP/IP has four layers. These
layers are named as application layer, transport layer, internet layer and
network access layer. These layers handle the data transfer by sending it down
from the first application layer and then lastly to network layer so that proper
transfer of the data can be achieved. The control of the information is the
header and it gets attached to the data whenever it passes to the next layer.
The header of first layer is removed by the next layer and a new header is
added.
Transport layer use two protocols and that are Transmission Control Protocol
(TCP) and User Datagram Protocol (UDP). It helps in getting the proper
transfer service of the data in addition to error detection and its solution. UDP
is important as it provides the low-overhead and non-connectivity service
8

with the help of IP address. It has two types of ports source and destination
port. When TCP is discussed, it involves the use of connection oriented and
byte stream protocol. The mechanism used in this protocol is
Acknowledgement with Re-transmission (PAR) where sequence rules are
used for data transfer. These protocols help in transferring the information and
data from the application layer to the internet layer.

Week 5
Task The Internet of Things (IoT) is a system of interrelated computing devices
that are provided with unique identifiers and the ability to transfer data over a
network without requiring human-to-human or human-to-computer
interaction. Discuss the cyber security challenges faced by the health sector in
this IoT era.
Summary Title and Reference:
Abraham, S 2016, Internet of Things (IoT) with Cloud Computing and Machine-to-Machine
(M2M) Communication. International journal of Emerging Trends in Science and Technology
Summary:
Internet of things is the infrastructure that joins number of devices with the
internet so that they can be accessed easily. This is achieved by establishing
the network using embedded sensors. Internet of things provides such a
functionality which develops greater interaction of device to device with the
help of IOT technology. It helps in developing advanced interaction and with
the advancement of the technology humans’ dependency on IOT also
increased. This resource is highly relevant to the task as it explains the
interrelation of computing devices without the requirement of human-to-
human or human-to-computer interaction. In this resource that I have selected,
the authors explain the technology of the IOT which includes the use of
internet-ready and connectivity-empowered embedded devices. Here is the
description of concept of IOT and this journal describes the different
functionalities of the IOT.
There are various securities challenges in IOT era when used at the health
sector. The challenges are related to the storage and security of huge
information that is collected from the institutions related to the health sector.
This huge data requires large data warehouses and it also requires different
algorithms to restrict the data redundancy during the storage. The power that
10

is associated to the IOT devices may also affect the efficiency of the network.
The personal information is stored at the databases of the institutions and
organizations in the health sector and it must be protected from the threat
agents. The threat can be occurred with the help of attacks on the IOT devices
and network. The market of IOT in health sector is very wide and helps in
bringing different types of techniques and with this many challenges will also
be faced with the IOT era. The internal threats may be developed within the
organization to cause internal threats and this can also be a great challenge to
the health sector (Kim, 2016).

Summary:
IOT cloud emerged as main part of the communication system in the recent
years and utilizes the internet to use different types of things so that a proper
communication can be established between human and IOT devices. When
the concept of cloud is discussed, it is one of the strongest components of the
IOT and thereby can be used in different applications as suggested by the
author. Many service providers are now suggesting about the IOT Cloud as it
is easy to install and many devices and humans get interconnected through
ubiquitous, accessible and on-demand network that can share a large
configurable of computer resources. Humans started to find their interest in
the virtual based things and service providers start focusing on the IOT cloud
so that human can connect their device to network as much as possible. I have
taken this resource for the task and relate to it in every manner and explain all
the aspect of facilities given by the technology of the IOT. Author clearly
wants to state the IOT concepts and its advantages that affect the lives of the
human in various ways.
