Ethernet II Frame Part 2: Use Wireshark to Capture and Analyze Ethernet Frames Part 1: Examine the Header Fields in an Ethernet II Frame What is significant about the contents of the destination address field? It starts with the broadcast ARP protocol from the router asking who has 192.168.2.22. Then it starts showing the source ip address then destination addresses then rebroadcasting from your router. ____________________________________________________________________________________ ____…

This article by the New York Times describes what Trump’s promises mean in accordance with the Paris Agreement. Although the agreement does not rely solely on the United States, we are hold a large role in influence for other nations to cut back and have been on track for improvement over the last few years. If America does retract its agreement, other countries have threatened to tax or altogether deny imports and exports from the U.S. The combat against climate change began with the Obama…

The United states should not have pulled out of the Paris Climate Accord because the view on america is bad enough, the earth is ill and creating jobs strengthens that illness, and the long term goal set by the Accord is much more important than some think. To begin, receding from the Paris Climate Accord shows a great sign of weakness and inability to commit, resulting in an even more rapid decrease in positive views from other nations on the United States, as even the U.S. could not agree to…

What is a VPN? It stands for virtual private network. Its main purpose is to secure the connections between the host and the server. It fulfills that purpose by using tunneling protocols, encryption, data encapsulation and certified connections to protect the identity of the host. The simplest way to think about it is to compare it to a LAN connection but without wiring. The History of VPN: Early VPNs were often set up to give individual employees secure remote access to their company…

A Performance Assessment of the Kyoto Protocol Introduction The Kyoto Protocol, adopted in 1997 by the United Nations Framework Convention on Climate Change (UNFCCC), was designed to address the global emissions of greenhouse gasses. Effective in 2005, it provided legally binding targets for countries which varied depending on the level of development of the country as well as contained certain measures for collaboration between countries for trading credits. Evidently, to successfully reduce…

Global warming has been taking effect on the Earth’s environment since the 1950’s creating dramatic changes and dangerous new records. In the last three decades the Earth’s average surface temperature has each been successively warmer than any previous decade since 1850 as a result of increase greenhouse emissions (IPCC 2014). This temperature rise is impacting some of the most vulnerable ecosystems on the planet such as the polar regions, coral reefs and tropical rainforests. Climate change can…

Climate change has been a long-term global issue that requires collective global action in the form of flexible yet stable policy implementation by the global actors. As a global actor, Australia’s approach and commitments to action on climate change, has been considered as inconsistent and lacking in direction (Talberg, Hui & Loynes, 2013). Nevertheless Australia’s climate reputation has not always been a negative one, in the early 1990’s Australia’s reputation was even seen as…

It means that the packet originated from somewhere else and that is why it didn’t take the expected best path. The only disadvantage to this system is that it is not feasible on path vector based routing system. A path vector protocol is a computer network routing protocol which maintains the path information that gets updated dynamically. Updates which have looped through the network and returned to the same node are easily detected and discarded [3]. Now current Internet uses BGP which is in…

A general definition of a home network would be the interconnection between two or more computers to establish a local area network inside the home. With the advancement of the technology, the notion of computers has changed because many devices can do the same job that computers do. Therefore, let us define a home network as a local area network that allows digital devices present inside of a home to communicate together. We will enumerate a list of Home Network devices and we will write…

"It is urgent and the timeframe is critical and it has to be right now," said Vicki Arroyo, executive director of the Georgetown Climate Center at Georgetown Law. "We can 't lose another four years, much less eight years" (Neuhauser). The next Americans President, experts say, may be the very last who can avert catastrophe from climate change which makes it very important for the next American President to give climate change the top most priority. This requires the Presidential candidates to…
