Evolution of Ethernet

* 1973 - Bob Metcalfe, working at Xerox's Palo Alto Research Center, was told to come up with a way to link hundreds of computers to the company's new laser printers. Metcalfe created a diagram describing a design for Ethernet at 3Mbps over shared coaxial cable. * 1976 - Metcalfe and David Boggs publish a paper entitled: "Ethernet: Distributed Packet-Switching for Local Computer Networks." The paper defines multipoint data communication system with collision detection. * 1979 -Metcalfe leaves Xerox and founds 3Com. The next year, he publishes standard for 10Mbps Ethernet, known as the DIX standard (for Ethernet backers Digital, Intel and Xerox). * 1985 - The IEEE becomes the official standards body for Ethernet. Open standards help make Ethernet the dominant LAN technology. * 1986 - IEEE publishes standard for 10Base5 Ethernet, also known as thick Ethernet because it ran over yellow coax that resembled a garden hose. * 1989 - Start-up Kalpana introduces first Ethernet switch, which eventually replaces bridges and hubs. The Cisco Company buys out Kalpana. * 1991 - IEEE approves 10Base-T Ethernet over Cat-3 twisted pair cabling, which becomes the standard for LAN deployments. * 1994 - IEEE approves 10BaseF, Ethernet over fiber for use in data centers. * 1995 - IEEE adopts standard for Ethernet at 100Mbps. It becomes known as Fast Ethernet. * 1998 - Standard for 1000Base-T or Gigabit Ethernet is approved. * 2002 - Pre-standard products start shipping in 2001, but formal standard for 10Gigabit Ethernet is approved in 2002. * 2015 - First pre-standard 40/100 Gigabit Ethernet products slated to ship later this year. Standard expected to be ratified in mid-2010. IEEE says it will then start working on terabit standard, with a goal of completion by 2015…...

Evolution

...The theory of evolution, formalized by Charles Darwin, is as much theory as is the theory of gravity, or the theory of relativity. Unlike theories of physics, biological theories, and especially evolution, have been argued long and hard in socio-political arenas. Even today, evolution is not often taught in primary schools. However, evolution is the binding force of all biological research. It is the unifying theme. In paleontology, evolution gives workers a powerful way to organize the remains of past life and better understand the one history of life. The history of thought about evolution in general and paleontological contributions specifically are often useful to the workers of today. Science, like any iterative process, draws heavily from its history. It is a FACT that the earth with liquid water, is more than 3.6 billion years old. It is a FACT that cellular life has been around for at least half of that period and that organized multicellular life is at least 800 million years old. It is a FACT that major life forms now on earth were not at all represented in the past. There were no birds or mammals 250 million years ago. It is a FACT that major life forms of the past are no longer living. There used to be dinosaurs and Pithecanthropus, and there are none now. It is a FACT that all living forms come from previous living forms. Therefore, all present forms of life arose from ancestral forms that were different. Birds arose from nonbirds and humans from nonhumans. No......

...Search for Evolutionary Proof Arjumand Parham Sci 115 7/24/12 Dr. Freeman Search for Evolutionary Proof “Our ability to grasp, to build, and make out thoughts real lie inside this complex system of bones, nerves and vessels.” –Neil Shubin These things would only be possible through evolution. Evolution is any process of formation or growth and development, without it we wouldn’t be here today. Evolution though only an theory has an massive backing within the science community; many fossils, scientist and scientific studies have all but proved evolution indefinitely. The proof for evolution is massive and profound; fossils and carbon dating are absolute proof that creatures very similar to us not only lived but were evolving and walking around. African hominids such as the bipedal Australopithecus afarensis or “Lucy” are some of the most profound examples of evolutionary history. Unlike a common monkey Lucy was a bipedal specimen which meant she walked upright much like an human. What makes her such an amazing discovery is the fact that she was about three-million to almost four-million years old. Scientist from every side of the spectrum have gathered to try to make this theory fact. Neil Shubin paleontologist and archeologist said” We were not designed rationally, but are products of a convoluted history”. The history of the human body is convoluted in every sense of the word; there are approximately three-billion-five-hundred-million years of history in the......

Ethernet Wire

...Ethernet Cabling Pin-Out On the back of each keystone jack is a two-sided connector that is labeled with similar colors. In the keystone jack we're using, the label has sets of colors labeled A and B. This refers to the two main wiring standards used in Ethernet, 568A and 568B. You can use either standard as long as you are consistent with that standard throughout your installation. Using the 568B standard, the left side of our keystone jack is labeled (from top to bottom) blue, white-blue, orange, whiteorange, and the right side is labeled green, white-green, brown, white-brown. Working from the top, place the specified color in the corresponding slots on the top row of slots on connector. Try not to untwist the wire, since the Ethernet standard requires the wires stay twisted down to the last 1/2 inch.

Ethernet or Token Ring

...Ethernet or Token Ring Ethernet or Token Ring I had an issue with this question that I have to address before I answer it. I understand that the answer that you are looking for is token ring for this scenario but the scenario lacks appropriate detail to really make the decision. It does not tell you the specific type of setup that the bank has or if there even is one. Not to mention that token ring is almost completely dead as far as LAN is concerned. There is no reason that the bank could not use an ethernet setup to accomplish its set goals. I just wish the assignment as a whole would be a little more detailed. That being said lets get to the scenario. Saguaro Federal should use a token ring. I say this because of the topology and function of a token ring. The general overview of a token ring is a circle. Within this circle each system is connected through a MAU by either UTP or STP. The token refers to a data packet that travels around the ring to its destination or destinations. The bank would benefit from a token ring because of the closed aspect of the network, and also because of the one way traffic that happens within the ring. You would avoid data collisions and by using a token ring you can predict the travel time of your data packet arrival. The security aspect of a token ring suits the needs of a financial institution, but also costs more money and difficult technical aspects. XYZ Technology Consultants would benefit for an ethernet setup. ......

Evolution

...The beginning of the earth has been a mystery, boggling the minds of the erudite and the simple minded alike for years. The topic of creation vs. evolution has become increasingly controversial. In biology, Darwin’s Theory of Evolution is a change in the genetic material of a population of organisms from one generation to the next. Though changes produced in any one generation are normally small, differences accumulate with each generation and can, over time, become substantial changes in the population. Such similarities among species suggest that all known species are descended from a common ancestor (or ancestral gene pools process of gradual divergence). Evolution is supported in many different ways, but one major category pointing to its validity is fossils. Through fossil dating, hominoid fossils, and, evolution has become the theory accepted by the majority of those in the scientific forefront. Evolution is supported through fossil records. The study of the sequence of occurrence in rocks reveals the relative time in which organisms lived. This technique shows that one layer of rock is older or younger than another. Later through the discovery of radioactivity, scientists were given the opportunity to learn the age of fossils and rocks . Through these records, a vague timeline is illustrated of the evolutionary change that has been occurring over the past four billion years. This proves that the earth is much older then creationist would like to argue. A popular......

...Ethernet standards continue to transcend boundaries and play ever-expanding roles in global communications, from fast Ethernet to 1terabit Ethernet standard. IEEE, the world's largest professional organization advancing technology for humanity, celebrated Ethernet's 40th anniversary on May 22 2013. IEEE 802.3 "Standard for Ethernet" and the varied technologies, applications and networks that the family of standards helps enable have changed the world as we knew it, and multi-dimensional innovation never stops. Frontiers of IEEE 802.3 Ethernet innovation include ever-increasing speeds and new applications for the technology. For example, in April 2013, IEEE announced the launch of an IEEE 802.3 study group to explore development of a 400 Gb/s Ethernet standard to efficiently support ever-increasing, exponential network bandwidth growth. Fast-growing IEEE 802.3 Ethernet application areas include energy efficiency, the globally emerging smart grid, data centers and supercomputing, access networks, mobile-communications infrastructure, healthcare and medical-device communications, entertainment and networking for automotive and other industries. Furthermore, in both developed and developing areas of the world, IEEE 802.3 Ethernet is being deployed with infrastructure build outs to support the exploding array of applications that users rely on in their every-day lives. Initially developed in order to standardize connectivity among computers, printers, servers and other devices......

...Table of Contents Introduction 2-4 Reasons 4-5 Advantages 5 Disadvantages 5 Summary 6 Reference 7 Introduction     The Ethernet is a system used in the connection between a number of computers to form a Local Area Network(LAN), which consist of the physical and data link layer. During the 1980s, one of the first widely deployed Ethernet supported a theoretical data rate of 10Megabit per second(Mbps). Over the years through the advancement of technology, the maximum data rates were increased to 100Mbps to todays peak performing a whopping 1Terabit per second(Tbps), but only active in area of research. As workplaces slowly become a more computerised and network based, with the rise of emails and the internet, Ethernet has become more prevalent. Every computer that requires a connection to another or link to systems uses the Ethernet. The computers you use at home, in your office at work, in school that accesses the internet through the use of the Ethernet.     Ethernet LANs consist of network nodes and interconnecting media. The network nodes fall into two major classes: Data terminal equipment (DTE) - Devices that are either the source or the destination of data frames. DTEs are typically devices such as PCs, workstations, file servers, or print servers that, as a group, are all often referred to as end stations. Data communication equipment (DCE) - intermediate network devices that receive and......

Evolution

...Evolution within the field of Physical Anthropology is the Idea that “species change over time and have a common ancestry”(Park 2009, p36). With this in mind, the field of Physical Anthropology, also known as Biological Anthropology, can be used to explore and investigate the evidence of the human evolution. Within Biological Anthropology, evolution is observed as the change of humans and human ancestors over time. These changes that occur do not take place over night, nor do they happen over a decade. It takes thousands of years to produce changes in an organism to the effect that it would be classified as evolution. Physical Anthropologists study the remains of Hominins and other ancestors of humans to discover the link that connects us all. They also study other creatures to compare them to humans in an effort to understand where humans come from and what makes us human (Gonder, 2013). One way that Physical Anthropologists have found links of evolution from early Humans and Neanderthals is through dental evidence found and investigated by Professor Alan Mann. He concluded that modern humans did in fact evolve from Neanderthals by finding links in the dental history of each species. Though his evidence is disputed by some, like any other scientific evidence, there have been some that support him and have come to the same conclusion of the relationship between Humans and Neanderthals. One piece of evidence that supports his theory is from a group of researchers from......

Is3120 Unit 2 Assignment 2 - Evolution of Ethernet

...Evolution of Ethernet Given the speeds of today’s Ethernet and the progression of the speeds, 10 to 100Gigs over 8 years and 100Gig to 1Tb since, transmission rate will double again in about 8 years. Although this seems true, I read that Ethernet fabric will rival fiber optic transmission capabilities. We must keep in might that a network is only as fast as its slowest component. This means computers will have to continue to get faster at processing requests and switches and routers will have to analyze and forward data packets at a higher speed to keep up with the evolution of Ethernet. Cat5e, Cat5 and CAT6 are the most recent Ethernet Evolution; they are the standard and most easily affordable for companies to use. The ease of installment is also a big factor when using CAT cables, twisting and lining up the end connectors is all that is required. The biggest issue with using CAT is that in starts to lose signal after 100 meters, it needs to be sent through a repeater, or a switch to regain signal strength. For the cost, performance and ease of installation the CAT5e is the best medium for a LAN. The next steps ethnet will be taking will be to increases speed and security. An organization using medical equipment or financial information has to consider what security protocols and policies it would use. Using Category 6 twisted pair cabling. These cables are hardier versions of Cat5E and are covered in a shielding that prevents them from being compromised by......

Ethernet Token Ring

...[Ethernet or Token Ring] [Ricky Clark] [IT/242] Due: [6/20/2014] [Sokly Vann] Saguaro Federal has mainframes for all of its banks and businesses. Must the company use the Ethernet or Token Ring protocol? Explain your choice. Why is this choice appropriate? In this particular situation I would have to say that the token ring protocol should be used for its banks and businesses and the reason that I say this is because the banks and business seem to not all be located in the same building they are spread out. In Token Ring LAN’s each station is connected to a wiring concentrator called a multistation access unit using UTP or STP. The access method which is used on a Token Ring is called token which is a special data packet that is generated by the first computer that comes online in a token ring network With this being said this seems the most reasonable and secure because the computers cannot operate without a token from the other. XYZ Technology Consultants has offices on the second, third, and fourth floors of the office building it occupies. Must the company use the Ethernet or Token Ring protocol? Explain your choice. Why is this choice appropriate? In the XYZ technology consultants situation I would suggest an Ethernet protocol. The reason that I came to this conclusion was due in part of the company being located in one building on various floors so everything is central. Ethernet is the most used networking that is available because of the pricing......

...Evolution Abstract One paragraph… The discussion on the origin and fate of the universe continues to revolve around creationists and evolutionary ideas, though creationism positions arise mainly of religion and philosophy, while the evolution is postulated mainly from science. One wonders if possible convergence in these fields in the discussion, that is, if you can address both creationism and evolutionism from science, philosophy and religion. Theory of Evolution In science the theory of evolution explains the huge variety of life arising by postulating a process of transformation through changes in genes that lead to new adaptations to the environment. By studying the genetic structure of living beings is a verifiable fact that they are related to each other and, therefore, aims to have a common origin as the emergence of new species due to the accumulation of changes that do diverge and take different paths to adaptation to the environment. In the scientific world, biological evolution represents the interpretative key of the living world. Life began about 3500 makes 4000 million years in the form of single-celled organisms without nuclei and took about two billion years to produce the first eukaryotes (unicellular organisms with nuclei), so the start was given very slowly. However, in evolutionary history there are times with a high evolutionary rate as the Cambrian period (540 to 520 million years, they were many forms of multicellular life). They also......

...being taught in schools. Although we are known as a Christian country, religious ideas in public places are frowned upon or replaced. Now, scientific theories- evolution and the big bang- are being taught as fact to students across the nation. This is a growing problem because evolution is not a fact, only a weak theory based on misinterpreted evidence. There are two types of evolution being taught. One type, also known as natural selection or species adaptation, is when specific changes occur in one species. According to Roger Patterson, author of Evolution Exposed, natural selection is how a species changes, or evolves, in short periods of time. For example, one breed of dog evolved slightly to create the many different breeds of dogs we have now. This makes sense. Why? All dogs are similar to each other. You could say the same for birds, fish, cats, or any other animal. However, the theory of evolution says every living thing on the earth- plants, humans, animals and microscopic organisms- originated from only one organism. This is unrealistic. Natural selection can be tested and observed. On the other hand, the theory of evolution should not be taught as logical, evident factual information because it has not been scientifically proven as most of the non-Christian scientific world would tell you. Along with evolution, a theory for the origin of life, we have the Big Bang Theory, a theory for the origin of our universe. According to Dr. Jason Lisle, author of The......

10 Gigabit Ethernet Standard

...10 Gigabit Ethernet Standard Christopher Burch PROF. K. Jones CIS 175 – Intro to Networking March 4, 2011 ABSTRACT NOT REQUIRED 10 Gigabit Ethernet Standard From its inception more than 25 years ago, Ethernet has adapted to meet the increasing loads of packet-based networks. Because of its proven low implementation cost, reliability, and relative simplicity of installation and maintenance, Ethernet’s usage has grown to the point that nearly all voice, video, and data traffic on the Internet begins or ends with an Ethernet connection. Further, as the need for ever-faster network speeds has increased, Ethernet has been adapted to handle these higher speeds, as well as the surges in volume demand that are apart of them. The IEEE 802.3ae 2002 (10 Gigabit Ethernet standard) is unique in some respects from earlier Ethernet standards in that it will only function over optical fiber, and only operates in full duplex mode (collision-detection protocols are unnecessary).Ethernet can now evolve to 10 gigabits per second while keeping its most important Ethernet properties, such as the packet format, and the current capabilities are easily transferable to the new standard. The 10 Gigabit Ethernet standard extends the IEEE 802.3aestandard protocols to a wire speed of 10 Gbps and expands the Ethernet application space to include WAN-compatible links. The10 Gigabit Ethernet standard provides a powerful increase in bandwidth while maintaining maximum compatibility with the......

...ION * PART A. Examine the mechanisms of evolution. * Evolution is the process by which modern organisms have descended from ancient ancestors (Evolution, N.D.) The four mechanisms that allow evolution to take place are genetic drift, gene flow, mutations, and natural selection. All of these mechanisms happen naturally and are necessary for evolution to take place. Genetic drift is the random change in gene or allele frequency with which an allele variation occurs in a small population. Genetic drift is simple change. Two different genetic drifts that can change the size of a population are the bottleneck effect and the founder effect (Campbell, Reece and Simon, 2004). The bottleneck effect occurs during drastic changes in an alleles population causing the population to have some alleles that may be underrepresented or eliminated completely (Campbell, Reece and Simon, 2004). Chance may affect the alleles population for generations until the population will become large enough to allow sampling errors to be considered insignificant (Campbell, Reece and Simon, 2004). Genetic drift in a new colony is called the founder effect (Campbell, Reece and Simon, 2004). It is likely to occur when a few individuals colonize an isolated area (Campbell, Reece and Simon, 2004). When a colony migrates away from a larger population its gene pool becomes least representative of the larger colony it migrated from (Campbell, Reece and Simon, 2004). Gene flow is the genetic exchange of......

...desirable traits that were once only prevalent in a few individual animals became common traits for entire species (Winston, 2009). There are countless amounts of evidence that suggest that humans owe their existence to evolution, however, many people are skeptical as to whether or not it is still occurring, and whether or not it is happening in the same way. Some scientists hold that the human race has reached “its biological pinnacle and is no longer capable of changing” (McKie, 2005, ¶1). Alternatively, some experts believe that humans are evolving faster than ever (Sample, 2007), and others believe it is still happening, just on different terms. There has not been any deciding evidence as to whether or not humans are still evolving, however, saying it isn’t happening is a very difficult position to defend. Gene mutations happen at random so saying that humans will never undergo any more evolutionary changes seems very unlikely (Douglas, 2006). Many scientists and evolutionists believe that the complexion of modern society is changing the means by which natural selection and, consequentially, evolution is occurring. The evolutionary trait of an advanced brain is what defines us as humans; ironically that same brain is what is allowing us to change the rules of evolution. As a result of a number of medical advancements, doctors are able to sustain life that would not have lasted back in Darwin’s time. This means that humans with genetic advantages are not the only ones......
