Summary:

The title of this paper is CPU-GPU processing and in which the author explains the fundamental concept to of graphics processing unit and the difference between CPU and GPU. The author first describes the architecture of CPU and GPU and it is an advanced version of the computer processing unit. According to this article, CPU is the main primary device of any computer system which is used to perform arithmetic logic and input-output functions. Moreover, GPU is a special type of component which is used to display an image on the desktop. The author uses qualitative data analysis and CPU uses several cores that communicate with caches. The main difference between CPU and GPU is that CPU can perform numbers of tasks at a time but GPU perform only image rendering step. CPU is also called as the brain of computer and GPU is very latest technology which can handle complex stage. It is a very fast cache but GPU is very complex use lots of math units. Therefore, this article is completely based on CPU and GPU and the main benefit of this article is that it identified key factors of GPU.

Find and summarise ONE resource that describes ONE other commercial IaaS provider that is NOT Google. The resource and your summary should describe how the IaaS differs from AWS.

Title and Reference:

Nazir, M., 2012. Cloud computing: overview & current research challenges. IOSR Journal of computer engineering, 8(1), pp.14-22.

Summary:

The title of this article is cloud computing: overview and current research challenges. This paper explains the fundamental concept of cloud-based services and how Microsoft, provide IaaS services to consumers. Cloud is an advanced technology which provides various kinds of services to many organizations and it has the ability to scale down and up their services requirement. Generally, this type of process is produced third-party sellers like Google, Amazon, and Microsoft. IaaS is infrastructure as a service which is a platform to utilize cloud-based facilities and Microsoft is another IaaS provider after Amazon and Google. In this journal, the writer identified various organizations which are providing cloud computing facilities and it is more flexible technology by which consumers can reduce cyber-attacks. Microsoft developed their IaaS which is called as Azure and it is very different from Amazon web services. AWS uses R3 optimization process but Azure uses D-series to optimize memory. AWS is an automatic process as compare to Microsoft Azure which is one common drawback of IaaS. For backup, Amazon uses third-party tools and Microsoft uses their own cloud services. Therefore, the main disadvantage of this journal paper is that it does not explain which types of technologies are used by Microsoft.

Summary:

The title of this paper is A Comparative Review of IPv4 and IPv6 for Research Test Bed. This journal is completely based on internet protocol and the author describes the fundamental working mechanism principle of both IPv6 and IPv4. According to the writer, IPv6 is still very low because it is not famous as compared to IPv4. The cost of this protocol is very high by which many users are not able to adopt this advanced technology. The main goal of this paper is the review on internet protocols and makes a comparison between IPv6 and IPv4. It is identified that the main difference between in this networks is addressing formats. IPv4 utilize 32-bit address and IPv6 use 128-bit which is more efficient for a large computer network. The author describes the concept of both internet protocols and investigated that address depletion is the very common problem for IPv4 and this problem resolved by the IPv6 network. Therefore, this article provides a proper explanation about internet protocols and use primary data analysis.

Summary:

The title of this paper is A brief study of Wanna cry Threat: Ransomware Attack 2017. According to this journal, ransomware is one of the most common cyber-attack which is growing very fast. Wanna cry is a part of this attack in which hackers produce complex botnet process by which they can easily determine the private detail of any authorized server. The main objective of this article is to describe the issue of Wanna cry and how hackers attack any server. In this modern generation information of any organization and community is very important and many users use the unauthentic website by which they can lose their privacy. In the year 2017 around thousands of computers are a hacker by the wanncry attack and it shares traffic signals to organization websites and target employee’s personal accounts. In which many attackers send spam emails and message due to which users click on fraud links and hackers collect all private details of their networks. This research paper explained wanncry cyber-attack and the impact of this problem on human personal life. Consumers can adopt security plans and programmes by which they can reduce this type of attack.

On March 17, the London Observer and The New York Times detailed that UK-based information firm Cambridge Analytica procured a huge number of Facebook clients' close to home data to construct programming that could target potential swing voters in political crusades, including US President Donald Trump's 2016 decision offer. Around 270,000 clients consented to have their information gathered and utilized for scholastic research in return for a little installment. The Times detailed Cambridge Analytica took care of the expenses of the application, more than $800,000.

Kogan gave data from in excess of 50 million Facebook clients to Cambridge Analytica, which was utilized by the organization to make 30 million "psychographic" profiles that could then be utilized to configuration focused on political promotions. Cambridge Analytica said on March 17 it erased all information got from Kogan's organization, Global Science Research (GSR) when it discovered it had not been gotten in accordance with Facebook's strategies. No information from GSR was utilized by Cambridge Analytica as a major aspect of the administrations it gave to the Donald Trump 2016 presidential battle. Kogan, in the meantime, said he felt scapegoat by Facebook and Cambridge Analytica. Truly we thought we were acting splendidly suitably

Summary:

Australia's greatest retail establishment, Myers, contributed a huge number of dollars on site advancement as it endeavored to help online deals. However every time the site got occupied, it slammed. Stock blowout sales have been tormented by framework blackouts, and on Boxing Day 2013, the entire site imploded. Senior administration communicated 'dissatisfaction' and statements of regret to clients.

Investors were informed that such framework accidents would not influence benefits. Since Myer skimmed in 2009 at a cost of $4.10 per share, the seller has seen its advertise capitalization plunge from $2.2 billion dollars to $429 million or 59 pennies for every offer. Under two years into the five-year turnaround, speculators, investigators and media beginning upsetting for change in light of an apparent absence of results and lost trust in the vision that had been upheld by the board. Australian retail needs Myer fit and sound. People require Myer 'right-sized' and gainful on the grounds that our retail chains generally drive a lot of market conduct and item lifecycle either emphatically or adversely relying upon their level of edginess. The main reason for this failure is the lack of resources by which they could not handle their business.
