Introduction
Nowadays, with the development of technology, the demand for high speed computing for the computers increases significantly. Cloud computing is the most emphasized Information and Communications Technology (ICT) which can effectively implement high speed computing [1]. Most common products that people used in their daily life such as cloud drive and Google search are based on cloud computing, therefore it is necessary to

The high rotation speed will cause not only the dramatic increase of temperature but also the loud noise. The low energy efficiency of HDDs is due to the heat loss which is caused by high temperature, and the friction in mechanical content of discs and air. As for the SSD, the data will be stored in the flash chip through the channel of transistors, so it does not require rotating [4]. It can save a massive range of energy which HDDs will lose when HDDs are rotating. It is extremely energy efficient to use SSDs in ICT equipment because the demand for writing or reading data is increasing dramatically. The drawback is that the price of SSDs is much higher than that of HDDs, so the SSD is difficult to be widely used until the price is reasonable. In addition, improving the energy efficiency of cooling system is also effective [5]. To be specific, it is important to use “right-sizing” cooling system, which can automatically adjust the power of cooling system [5]. The temperature for ICT equipment is variable, therefore the cooling system can increase the power while the temperature is high. On the contrary, the cooling system can decrease the power while the temperature is low. To successfully implement “right-sizing” cooling system, the data center operators should take additional methods to measure the temperature [5]. Thirdly, the energy efficiency of server processors is also helpful for reducing energy consumption
Rehabilitation is the alternative to punishment but exactly what is rehabilitation? Rehabilitation according to the Encyclopedia of Criminal Justice is defined as, “punishment intended to reform a convict so that she can lead a productive life free from crime,” rehabilitation is successful as long as the criminals are willing to accept the change similarly to the steps taken by alcoholics or drug addicts in rehab. Rehabilitation is a form of punishment but unlike other forms of punishment, rehabilitations objectives are more therapeutic rather than punitive. Rehabilitation is the best option for prisons because there are so many different sub categories that any prisoner willing to change should able to find rehabilitation whether they are
Are you familiar with the fact that pickle juice is as healthy or more powerful than the pickles themselves?
The questions in this exercise can be answered by doing internet search and/orfrom the YouTube videos. Answer to each question should be one paragraph in your own words.
Cloud computing can be viewed as one of the most rapidly growing and evolving paradigm.Webmail,online storage and online documents are most famous examples in which customers can access their data via web browsers on the internet. The original idea of the cloud computing was delivered by J.C.R Licklider in sixties (Mohamed 2009). Cloud computing has developed since then and started to server the publics after internet offered a significant bandwidth in the nineties (Mohamed 2009). Cloud computing has been through many different phases and is still rapidly evolving.
The Important of Cloud Computing is increasing and it is receiving a growing attention in Scientific & Industrial Communities. Cloud computing is one of the top 10 most important technologies and has a greater possibility in successive years by companies and organizations. Cloud computing implement everywhere, favourable, on demand network access to a shared pool of configurable computing resources (e.g. networks, servers, storage, applications and servers) that can be immediately supply and released with minimal management effort.
Modern data centers and hardware that focus on energy efficiency, high availability, security and scalability to provide a physical infrastructure for our new IT vision to grow
“Cloud” computing is the fanciest buzzword in the computer industry, currently surpassing the last big term “web 2.0”. Every big player in the computer industry launched a cloud service last year. Notable examples are iCloud by Apple, (Apple 2012) or Microsoft Cloud Services (Microsoft 2011), copying various innovators like Google or Dropbox, who offer similar services since much longer. The latter is the most successful
Cloud computing can be understood as a multifaceted infrastructure of hardware, software, storage and processing available to be used as a service. With the use of cloud computing, without even knowing how it works, one can access a large number of the most sophisticated supercomputers of the world and their respective processing powers without being overwhelmed with space or information. Cloud computing allows access to computer networks located at various places in the world and thus offers the speed of
Cloud computing is a “newsworthy” term in the IT industry in recent times and it is here to stay! Cloud computing is not a technology, or even a set of technologies – it’s an idea. Cloud computing is not a standard defined by any standards organization. Basic understanding for Cloud: “Cloud” represents the Internet; Instead of using applications installed on your computer or saving data to your hard drive, you’re working and storing stuff on the Web. Data is kept on servers and used by the service you’re using; tasks are performed in your browser using an interface/ console provided by the service. A credit card and internet access is all you need to make an investment in
I feel that this novel can relate to women especially teenagers. People can relate to this because I feel that the author captures the pains and troubles of everyday high school life with honesty and emotionally.The characters are relatable and the book is honest. This is an important book for the content and message it presents. It gives a lot of insight about troubles these victims have faced and speaks volumes about them dealing with issues. It is important for girls and they need to be aware and watchful and to also be compassionate if they know someone who has gone through this trauma. It explores the damaging effects of sexual assault I think the author has done a great job by sending out the message, that any kind of assault or abuse is a big deal and it is not something to keep quiet about. It explores the deeply damaging effects of sexual assault.
Cloud computing is one of the most useful technology that is been widely used all over the world. It generally provides on demand IT services and
As we all likely already know, there 's a LOT of hype associated with cloud computing. Cloud computing is a huge topic. It encompasses diverse models and technologies, even though
Abstract – Cloud computing is a type of computing that relies on sharing a pool of physical and/or virtual resources (e.g., networks, servers, storage, applications and services), rather than deploying local or personal hardware and software. This technology is mainly service oriented and focuses on cost reduction, hardware reduction and pay just for service concept. Virtualization in cloud computing is making a virtual image of the storage devices servers or network resources so that they can be used on multiple machines at the same time.
With the growing of technology and people around the world using the internet more often, the cloud is becoming more popular than ever before. The United States National Institute of Standards and Technology has defined cloud computing as follows: "Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction [1]." There are many uses of the cloud but the main uses people use the cloud for is to host websites, store documents, and to stream TV shows and movies. With all this new flooding of the cloud computing network, the dependability of cloud computing systems have come into question for all cloud service providers, consumers, and brokers around the world. Fig. 1 is just one example of the growth of cloud computing of a single company.
Cloud computing have revolutionized life as we know it; it allows people to store, manage, and access their data by using a network of remote servers which are hosted on the internet rather than using a local server or own hardware. A recent study conducted by KPMG found that 81% of businesses were either evaluating cloud services, planned a cloud implementation or had already implemented a cloud strategy [1]. Organizations tend to use the cloud to reduce costs and improve efficiency. Cloud is not a commodity, some people think that it comes out of the sky, while in fact it comes from physical hardware inside brick and mortar facilities which are connected to hundreds of miles by networking cables.
