Review question week 2
1) What is scalability? Base on my understanding scalability is refer as how much growth the business design must support. It’s important that we use scalability as our primary goal for network. Most companies like to add more users, apps, site or any external network connection that is why scalability is a primary goal for the network. The most challenges designers face when designing for scalability is usually expansion.
2) 100-99.80= 0.2%
0.2% * 365= 0.73 days
0.73*24= 17.52% hrs/day
17.52*7= 122.64% = 1 hrs and 22 mins downtime /per day
Hr/week = 8 hrs 58 mins downtime/ per week
Down time for minutes per day will be = 82 minutes
Downtime for second per day will be = 4920 second

3) For this question number 3 I do not have significant answer for it so I just going to try my best to answer it usually the technical problem with this issues is could be packet switching delay. Because the latency accrued when switches and routers forward data. The latency depends on the speed of internal circuitry and CPU, and the switching architecture of the internetworking device. or the problems could accrued from serialization delay. The time to put digital data onto a transmission line, which depends on the data volume and the speed of the line.

4) The two tools that I research on that attacker use are attacking on your password , access attacks or DoS attack.

Access attacks: first they will try to bait people go into get information from their own access and hack their way into it. Then find the way to get on to authentication services, then FTP service
Password attacks: password attack usually refers to repeated attempts to identify a user account, password or both. These repeated attempts are called brute force attacks.

Trans-Pacific Partnership

...Trans-Pacific Partnership The Trans-Pacific Partnership (TPP) is a commercial agreement pursued by the Obama Administration that rivals the WTO in scale. It would link Australia, Brunei Darussalam, Chile, Malaysia, New Zealand, Peru, Singapore, Vietnam, and the United States into a free-trade zone similar to that of NAFTA. Proponents of this partnership, which includes 600 corporations, declare that it will (1) support the creation and retention of jobs in the aforementioned countries; (2) boost competitiveness, thereby benefitting consumers in these regions and promoting economic growth therein, and; (3) increase the standard of living and reduce poverty in the countries[1]. The TPP is the first agreement negotiated from the ground up by the Obama Administration and represents an ambitious, next-generation, Asia-Pacific partnership. Through this agreement the Administration is seeking to boost the U.S. economy, by increasing exports to a region that includes some of the world’s most robust economies. The large and growing markets in Asia-Pacific are already key destinations for U.S. manufactured goods, agricultural products, and services suppliers. The TPP aims to further deepen this trade and investment relationship. The Obama Administration, in collaboration with Congress and a wide range of stakeholders, is negotiating to conclude this progressive agreement that aims to address the issues that U.S. businesses and workers are facing in the 21st century.

The Trans-Pacific Partnership

...The Trans-Pacific Partnership Agreement and the U.S. economy Executive Summary -The Trans-Pacific Partnership Agreement is a free trade agreement initiated in 2005 and was joined by the U.S. in 2008 which proposes to liberalize trade in the Asia-Pacific region. -Negotiations are ongoing and held in secret. While the FTA’s existence and meetings are public knowledge, most of the information is classified and kept from U.S. government officials. However, several documents have been leaked to the public through various sources. -There is much clamor and concern over the Intellectual Property proposals put forth by the U.S. These proposals threaten to dial back public health safeguards set forth in the 2007 New Trade Deal of the Bush administration, increase prices of consumer goods, and restrict access to information on the internet. -There are 12 countries involved in negotiations, with China as an observer and considering entry. Overall, these countries make up about 40% of the world GDP and offer access to huge markets for the U.S. Nonetheless, the threat of losing jobs overseas, as with most FTAs, is cause for concern. -Past FTAs have resulted in an increase in U.S. trade deficit and a loss of jobs. However, analysis shows that American firms can benefit from these agreements as well with increased exports to new markets. Brief History The Trans-Pacific Strategic Economic Partnership Agreement is a free trade agreement with the goal of liberalizing the......

Mcdonald's Trans Fat Lawsuit

...McDonald’s In 2003, the non-profit organization, (BTF), filed a federal lawsuit against McDonald’s for failing to reduce the amount of trans fat the company used in its cooking process. In 2002, McDonald’s had publicly announced that, by February 2003, they would voluntarily begin using an “improved cooking oil” to prepare their fried foods. Do so would significantly reduce the amount of trans fat in their products by 48% ("Mcdonald's exposed for," 2004). McDonald’s withdrew their promise and did not switch over to a cooking oil with less trans fat, nor did they reveal to consumers that the conversion did not take place. The company claims that they changed their minds when customers began complaining that they did not want the taste of McDonald’s food to change (Horovitz, 2007). BTF accused McDonald’s of false advertising, deceiving consumers, and not taking the health of their consumers into consideration. In their lawsuit, BTF claimed that “McDonald's failed to make clear to customers that the type of oil used to fry its foods (which contains TFAs) had not been changed” ("Responsible shopper," 2005). BTF did not seek monetary damages, they only asked that McDonald’s publicize their failure to switch over to the healthier cooking oil and make that conversion as soon as possible. McDonald’s claimed that it was taking longer than expected to change to a new oil, but they were working on implementing the exchange. They did not provide any information as...

...Trans-genders in the Military As time continues, things that we found unusual and unrealistic have become normal and not such a burden to us. The military has been a key role on moving forward with many of these hush hush discussions many try to sweep under the rug. Now that the military is allowing openly gay, lesbian, and bi-sexual personnel into the military, there should be no reason for them to discriminate on trans-gender personnel who are trying to serve their country. In order for us to go forward with my statement I need you all to be opened minded. We all have an opinion but in the end it’s up to us to make the change for our future. The Don’t Ask Don’t Tell (DADT) era was a time when homosexuals where not allowed to be who they where without getting in trouble. The term was coined after President Bill Clinton in 1993 signed a law (consisting of statue, regulations, and policy memoranda) directing that military personal could not openly be a homosexual in the military (Britannica, 2015). In order for Clinton to win his seat in the white House he needed his sponsors to support him and having openly gays in the military was not something they wanted. Even though Clinton was for it he had to satisfy his supporters. After many discussions and fights back and forth Clinton finally came to an agreement that homosexuals could join the military but not be opened about it. Many officers were overwhelmingly opposed to that approach, fearing that the mere presence of......

Trans-Atlantic Slave Trade

...The Trans-Atlantic Slave Trade took place from the sixteenth through the nineteenth centuries. During the Atlantic Slave Trade between twelve to twenty million slaves were brought to the Americas from Africa. An estimated two million Africans did not make it across the Atlantic to the Americas. The Atlantic Slave Trade was part of the Triangular Trade; trade that went from Europe to Africa on to the Americas then back to Europe, creating a triangular shape across the Atlantic Ocean. Millions of slaves were forced to come to the Americas from their home in Africa. This had many effects on not only Africa and the Americas, but the rest of the world also. So, what were the effects of the Atlantic Slave Trade? The biggest effect the Atlantic Slave Trade had was the help in the development of the Americas. Population loss and social disruption from trade caused the underdevelopment of Africa. The culture in the Americas also changed as the slaves brought their culture with them. Although there were many negative effects from the Atlantic Slave Trade there were also some positive ones. The slaves had a large impact on the development in the Americas as they caused the growth in agriculture and the economy. If the slaves were not brought over to the Americas, the development would not have been as fast or large. Because they were forced to work long hours and do jobs nobody else wanted to do. Because they were cheap labor, landowners could buy many so there would be more......

Trans Pacific Partnership Agreement

...ABSTRACT Trans- Pacific Partnership Agreement (TPPA) is now sound familiar to Malaysia, this is because that countries is one out of the twelve countries that involve in that agreement. The goals of the Trans-Pacific Partnership (TPP), a much-delayed but significant trade agreement between 12 countries in Asia-Pacific and the Americas pushed by the US are increasingly becoming clearer after ongoing talks reveal some of the intentions Washington is pursuing with this pact. The highlighted of the agreement is to increase in import growth is projected to outpace increase in export growth, as the reductions in import tariffs and non-tariff measures (NTM) are larger for Malaysia relative to the other TPPA countries. According to The New York Times, economists are sharply split over the positive and negative effects of TPP, and both "opponents and supporters of the trade accord have quickly seized upon whichever analysis buttressed their own views. ECIPE has said in 2014 that TPP "will be the first ‘competing’ economic integration that is large enough to have a considerable negative impact on Europe. In the long-term, the negative effects will come from dynamic impact, e.g. on investment, productivity and competitiveness". Pascal Lamy called the TPP ‘the last of big old-style trade agreements’. It has said to be a negative impact on the oil and gas sector whose share of GDP is 12 per cent. PETRONAS stands to benefit very little from TPPA as 74 per cent of its exports are to......

Trans Theoretical Model

...Introduction: Developed by Prochaska and DiClemente in 1983, the Trans-Theoretical Model is one of many popular theories, which is used to describe the event of changing a behavior. It is said that the Trans-Theoretical Model (TTM) is a theory of behavioral changes which "intentional behavior change is a process occurring in a series of stages, rather than a single event and that motivation is required for the focus, effort and energy needed to move through the stages” (Miller, W.R., Rollnick, S., 2002). What makes the Trans-Theoretical Model so unique, is that it describes how change occurs over time and not immeadiately. According to Prochaska & DiClemente (1983), this theory proposes that a person may progress through five stages of change when trying to modify their behaviors. In the first stage titled pre-contemplation, we have people who have no intentions of taking action, or wanting to change their behavior in the near future. Many peers suggest that the desire to change a behavior is usually measured within the next six months (Prochaska, DiClemente, & Norcross, 1992). Individuals in this stage are unaware or uninformed of the consequences of their behavior (Scholl, 2002), or they may have had a number of failed attempts and are reluctant to try again (Prochaska & Velicer, 1997). Prochaska et al. (1992), says the main component of pre-contemplation, is the person shows resistance to recognize or modify problem behavior. For an individual to move out of this......

Trans Pacific Partneship

...The Trans-Pacific Partnership (TPP) is an international trade agreement that is aimed creating an Asian-Pacific free trade area. The TPP arises from the Trans-Pacific Strategic Economic Partnership Agreement that was reached in 2006 by only four countries. Australia joined the TPP in 2008. One of the main reasons behind Australia’s interest in the agreement an estimated 70 per cent of country’s trade flows through this region . Currently, the accord is being negotiated by 12 Pacific Rim countries including Australia, the United States, Canada, Brunei, Chile, Malaysia, Japan, Mexico, Peru, New Zealand, Peru, Vietnam and Singapore. Once the agreement is finalized each member will have to harmonize the relevant regulations according to conventional TPP standards. The conclusion of the TPP is also expected to integrate the Australian economy into the wider Pacific region where the country will benefit from the substantial removal of tariffs and non-tariff barriers. Although the TPP is referred to as a free trade agreement, it is not exclusively about the trade. In fact, trade is only covered under five chapters out of a sum of 29 chapters. Two decades ago, the idea of incorporating labour standards in trade agreements was considered a far-fetched thought . The TPP is a peculiar transnational accord since, integrates labour standards as part of the commitments to be followed by each country. Essentially, the agreement seeks to provide a new benchmark that will enhance the......
