In The Era Of Artificial Intelligence, GPUs Are The New CPUs
Janakiram, M. S. V., 2017. In The Era Of Artificial Intelligence, GPUs Are The New
CPUs. [Online] Available at:
https://www.forbes.com/sites/janakirammsv/2017/08/07/in-the-era-of-artificial-
intelligence-gpus-are-the-new-cpus/#65aeb60a5d16 [Accessed 01 09 2018].
Summary:
I choose this resource, because it describe about GPU as well as CPU importance in
Computer system. Maximum computer users assume that the video cards were
designed for graphical uses in systems like games and all. These were purely optional;
it means they are not only designed for gaming and graphics. GPU’s found a new
place that increase usability of GPU’s in Machine Learning and Artificial Intelligence
as relevant as CPU’s. GPU is getting so much attention now a days, it use machine-
learning techniques that is used in cognitive computing. CPU’s are used for
calculation in sequential order, which means next processes wait for first process to
complete. Now a days multi core processors are used to speed up the calculation by
switch processes in different cores, but cores are so costly.
In terms of calculation, GPU’s have thousands of cores, which is capable to handle
millions of processes in parallel? Deep learning and graphic rendering have these
similarities. Nvidia has a programming model “CUDA” for rendering and build
parallel programs. Next generation of GPU is GPGPU, which is general purpose
GPU. They are used for parallelization, it have the power for deep learning
experiments. Intel also has Altera and Nervana, which can be programmed later for
future use. Google also launched Tensor Processing Unit or TPU, which is a chip that
is designed for complex mathematical operations with parallel programming
(Janakiram, 2017).

Summary:
This source is informing about future operating systems, which are based on artificial
intelligence. Those operating systems will be capable of managing complex
calculations to help people and company. Company can derive more benefits from
their resources and data. Now days every person wants all information at our
fingertips. In addition, they want this information immediate, accurate and actionable.
Using artificial intelligence modern operating systems have been able to manage and
schedule different activities with better performance. AI reduces or optimized their
resource and increase efficiency of operating systems. In current time, highly
optimized and efficient operating systems are designed on the bases of artificial
intelligence. Many organizations exploring ways to develop an Artificial intelligence
based operating systems that will support to managing different complex activities.
These operating systems known as cognitive operating system. Machine learning
algorithms are helpful to design these types of operating systems. AI based Operating
systems will be more efficient in handling of decision-making problem solving
processes. Benefits of AI based OS:
 Consistent decisions

Azure vs. AWS Cloud Service Comparison: Which One is Better?
Stackify, 2017. Azure vs. AWS Cloud Service Comparison: Which One is Better?.
[Online]Available at: https://stackify.com/azure-vs-aws-comparison/
[Accessed 21 September 2018].
Summary:
This article describes about Microsoft azure and services provided by this to different
organizations. I chose this article because it explains about Infrastructure as a service
and difference between two IaaS. Also, explain how they store data and provide
services to companies.
In the article, discuss about pricing and services of Microsoft Azure. Azure divides
pricing of services according to uses by consumer. There is a price calculator, which
shows cost of your services. Azure also provides Service as a service and platform as
a service with different services.
In addition to services types, IaaS provide languages at service side for development,
such as java, python, and ruby. It is provide software development tools for making
projects online, such as IIS server. In case of databases and storage, SQL database is a
database as a service. For storage of all data of different tables, it provides 200 TB
space.
It has only a drawback that it is provide a wide variety of services to an organization.
So if you want a specific type of service than it will be difficult.
Amazon Web Services (AWS) is biggest competitor of all IaaS. AWS is a reliable
option for such types of services. However, in last decade many things are changed.
Microsoft Azure provides services into three categories, such as Networking,
compute, and data management and performance.
I found this article useful because it provides details about Microsoft azure services
and compare it with AWS.

Title and Reference:
What is IPv6?
Whatismyipadress, 2018. What is IPv6?. [Online]
Available at: https://whatismyipaddress.com/ip-v6
[Accessed 18 September 2018].
Summary:
This source is described about IPv6 protocol and also compare IPv4 protocol. IPv6
handled packets more properly. Internet Protocol version 4 (IPv4) is network layer
standard protocol for communication between different networks. It is used for packet
switched network.
Some characteristics of IPv6 that makes it better than IPv4 are larger address space,
stateless auto-configaration, multicast, security at network layer, and qualities of
services capabilities. IPv6 vulnerabilities are making more secure data and system
from viruses and other attacks. Increased address capacity of address remove
subnetting problem in IPv4. It provides additional web addresses to resources. IPv6 is
more efficient in routing compare to IPv4.
It allows for easy aggregation of prefixes assigned to IP networks. It enables big data
packets to be sent in network simultaneously to better usages of bandwidth. It is built
authentication methods into network firewalls.
Some disadvantages of IPv6 are conversion, communication, transition, and
readability. IPv4 addresses are expressing in 32 bits. It is divided in two parts. First, is
network id and second is host id. In 1980’s, network is based on classful networking
but number of users are increased so it replaced with classless inter-Domain routing.
This is a logical addressing system. IPv6 is more innovative than IPv4 version.

2018].
Summary:
This resource is about ransomware and malware attacks. WannaCry is a worm of
ransomware type that damages a number of networks rapidly in May of 2017. It
encrypts files of windows computers hard disks. Also not accessible to users of that
particular system. For decrypt, that files it demand a ransom in bitcoin. First time it
spread in Britain’s National Health Service. First, time it discovered by United States
National Security Agency.
I select this resource because its explain about ransomware attacks on computer
systems.
What is WannaCry Ransomware:
It had many components. It is in the form of dropper on the infected systems, it is
self- contained programs that encrypt other files and programs. Three main parts of
this ransomware are:
 A program that change format of data in the system
 Make encryption keys for all files in the system
 A copy of TOR
WannaCry tries to open system files in the computer system and change these files in
other formats like Microsoft office files in the mpeg and mkv formats. Also, make
these files to not accessible for users then demanding $300 in bitcoin to accessing and
decrypting these files. Microsoft security has released patches on march 14, 2017 to
prevent infection from EternalBlue. These update the windows with implementation
of SMB protocol. Some peoples are paying the ransom, for accessing to their files.
Maximum system, which are infected by WannaCry ransomware have windows 7
operating system. Security teams start working to evaluate the origins of WannaCry
ransomware. Symantec security team had believed that the ransomware might have a
working company of North Korean origin. Boeing was hit with a suspected
WannaCry Attack in March 2018. It did little damage in few production systems.
NotPetya virus is encrypts the computer system master file table and showing a
message on screen requesting a Bitcoin ransom to decrypt files and access to the files

network-architecture/ [Accessed 21 September 2018].
Summary:
This article describes about Software Defined Networking (referred as SDN) and uses of
OpenFLow. . I chose this article because it explains about overflow and SDN within
different aspects of network. It is designed to manage data flow and internetworking
devices. SDN architecture have three layers are:
 Application layer – it provide communication services for end-user boniness
applications
 Control Layer – it consist the logically centralized functionality
 Infrastructure Layer – it provides packet switching and message forwarding
In this resource technical description is well defined. SDN has logically centralized
intelligence, which provides decision-making facility to domain. It is also controlled by
software. There are many Application-programming interfaces to interact with the
network. In the field of networking OpenFlow-enabled SDN, provide several benefits
such as multi-vendor networking. OpenFlow is provides connection between different
geographical domains for managing operations and complaints. Now a day’s operator
needs their transport networks with high bandwidth and shifting traffic patterns. SDN
provides all these facilities to maintain network according to their needs. SDN
architecture has a central controller, which perform many difficult functions, including
security attacks, routing algorithms, network policy declaration, and naming. A single
controller is deploying in large enterprise network to manage all networking devices.
These are called SDN domains. SDN domains provide scalability, privacy and
incremental deployment. The SDN controllers implemented in different ways, first it is
require an identical logical switch function and second, it needs a safe and a standard

from-legacy-systems/ [Accessed 03 09 2018].
Summary:
This resource is about disadvantages of Legacy systems. Legacy systems are known
as a system that continues the business from a long time. This could be holding any
organization back. Therefore, there is a difficult question arise in front of
organizations is that: Should they stick with their existing systems? On the other
hand, spend money for new system with latest technology. A good example can be
found in banking sector, where frequently changes are necessary according to
requirements. That was necessary for reduce risk and increase capabilities according
to market. Sometimes organizations do not have a choice to continue their legacy
systems. For business development and industrial strength, it is necessary to replacing
core systems.
Some questions to ask for changing legacy systems:
 How cost-effective is our system maintenance?
 Can current system integrate technology and system architecture?
 Current system still offering anything for organization business?
I select this resource because it is describe about legacy system disadvantages. There
are many other reasons to remove legacy systems from an organization, such as cost
of maintenance, lack of understandings, lack of security issues, and integration of new
systems with older technologies. IT systems makes better to an organization working
process and change business growth of an organization. Information technologies
attach previous or current system to mobile phones for easy and fast access from

from-the-qld-health-payroll-fiasco-/news-story/
174743f09e91d9550521b04d45d43ac3 [Accessed 21 September 2018].
Summary:
This article describes about IT project failure in Australia and learning from it for a
profession as well as a department. Queensland Health organization decided to
change their older payroll system with new system, for that they contracted to
Software company IBM in 2007, to analysis the requirements and design and build a
system for margining payroll at their organization. In addition, when it did go live,
there are many issues, thousands of employees were poorly paid or not paid at all. The
Queensland taxpayer is estimated at around $6.19 billion for the total project.
I select this resource for find different reasons of that project failure.
There are many calculation issues in that project for requirements. They also make
some communication gap between older and new system designs. When project aims
are not clearly defined in requirements, then cost is almost certain to be blown
through. This project has Over optimistic expectations. Expectations are too high so it
takes time to complete. The project is too complex. When complexity is high, of a
project than integration is also high with other systems. Project faces many complex
difficulties like conversion of data and high demand of resources. “Poor project
governance” is the three words for the failure of IT projects. Lack of resources is one
of the reason of project failure sometimes, but because they are not administrated
well.
I found this article useful because it describes Queensland Health payroll system
failure and how it was useful for learning from this incident for future.
