...Examining Ethernet Changes through the Years ITT Technical institute, CA: IS3120 9/29/2014 The Ethernet and IEEE 802.3 CSMA/ CD LAN technologies are the most popular LAN technology in the world today. Inspired by the ALOHAnet paper written by Norman Abramson is entitled “The Aloha System – Another Alternative for Computer Communications.” It described the development of an innovative radio-based network of computers that came to be known as ALOHAnet. In 1973, Robert (Bob) Metcalfe was a recent Harvard Ph.D. graduate working at Xerox's Palo Alto Research Center (PARC). During a visit with a friend he had came across the article he was inspired to collaborate with David R. Boggs and they put they had put there thought together. So using an IBM Selectric Typewriter with an Orator ball, Metcalfe typed a memo and sketched a quick schematic that would forever change both networking and the world at large. Then the Ethernet was born on May 22, 1973. The Ethernet was actually introduced to the commercial marketplace in 1980 was distinguished by its high speed (10 Mbps). During the 1980s to the 1990s Ethernet LANs dominated due to the ease of implementation and migrations for the LANS base on the 10, 100, and 1000BaseT LAN Standards. The Ethernet LAN technology had solved business challenges and the connectivity of business challenges. By doing this the cost was lower the early introduction of the token ring. Some of the business challenges were: * The need to connect to...

...* What impact will the continued evolution of the Ethernet standard have on data storage requirements, assuming capacity continues to follow the same pattern of progress? Bandwidth will soon far exceed capacity * What network devices will be required for the configuration of a VLAN-enabled Ethernet network? Gigabit switches * What statement can be made about the rate of progression in data transfer capacity in Ethernet standards? Speeds mostly have to do with how much one is willing to pay for faster data connection. The deciding factor is how important is the data from which is needed to be collected. Slower standards are just as good as faster ones depending on of course, the capacity in which it is collected and infrastructure· * If an organization decides to implement a medical imagery repository for radiological reviews, requiring 100Mbps connectivity for eight workstations operating at the same time, what is the minimum Ethernet standard to implement? Briefly explain the reasons behind your selection. Although fast ethernet 100Mbps would be sufficient, 1000Base-T would be better recommended for future growth. Ethernet has been the standard for networking for over 40 years. Future still looks promising with standard speeds of over 1Tbit on the horizon. Evolution of ethernet: * 1973 While Robert Metcalfe worked for xerox, he was asked to come up with linking hundreds of computer to laser printers. Came up with Ethernet at 3Mbps over shared coaxial...

...Joshua Malone IS3120 Unit 1 Assignment 1 When it comes to the Johnson Company they are behind in the aspect of customer service relationship. They are only getting customer orders through telephone calls and by taking customer orders by hand. In these days and times not many companies and businesses can start and continue to operate regularly with just these practices. To help this company they should try to implement networking and other electronic means such as a website and monitoring what customers are interested in. By doing these practices they reach out to new customers in many ways. The first and most important way is that it broadcasts to new and potential customers products that they may potentially want to purchase. It also brings in new customers that usually do most of their purchasing of items through the internet. Lastly it gives new customers an awakening to the fact that the business is here. By implementing these means Johnson would stand out from other companies in many aspects of the business world. First and foremost it would get them more customers who mainly search the internet for their goods. Secondly it would help beat out other companies and businesses that only sell products through face to face interaction. Finally it increases their professionalism by showing they can do face to face and online transactions. Finally these methods would meet customers updated and informed and also meet the customer’s needs by what the methods can provide...

...Data storage center centers will benefit greatly from the continued evolution of Ethernet. We saw in the past and present how Ethernet protocols enabled faster transmissions of data. How Xerox was able to network thousands of computers to a common printer. We even seen the benefit of collision management introduced in 1971. Data centers will improve the security of the cloud making it more cost effective to have virtual/roaming desktops. This will better enable companies to spend less on sky-scrapers by having most employees work from home. The hold back will be the telecom industry commonly referred to as ISP (internet service providers). Most of these companies have hesitated on the implementation of Gigabit connections due to the current high cost. VLAN-enabled Ethernet networks require switches and routers. The switches connect the users in a specific geographical area together and to a common connection to routers, one being for traffic and the other being a dedicated firewall. VLANs enable corporations to “hide in plane site” over the internet while still having the benefit of mobility like VPNs. 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...

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.

They are in need of new methods of communication for reaching out to new customers, standing out from other businesses, meeting existing customer needs, and keeping customers informed of news and updates. The Johnson Company still uses analog phone lines and still takes customer orders by hand. Their only current method of advertising is an ad in the yellow pages. They have reached out to our IT consulting firm to help them update their current business processes and communications Setting up an intranet site is one of the best ways for small businesses to keep all their workers in the loop and communicate new information. The Johnson Company can also use Microsoft SharePoint application and services to set up internal websites designed for specific projects. Providing customers with a website capable of taking online orders while advertising online as well would give the customers ease of access and efficiency. Project managers can also use these specialized websites to share documents and information, and this can help the projects run more smoothly and effectively.

Another situation where and argument of Xbox Live chatter between a Canadian and a Texan turned serious when the latter gamer disclosed plans to shoot up his high school. The Texas gamer began by detailing his troubles in school to a Port Alberni, British Columbia Xbox Live opponent, which was normal enough, but eventually the Texas gamer spilled details on plans for attacking his school, including rattling off the names of fellow students he was going to target. The talk alarmed the B.C. gamer enough that he contacted local Royal Canadian Mounted Police personnel, who started a cyber-investigation. The RCMP contacted Microsoft and was eventually directed to a teenage suspect in San Antonio, Texas, who was arrested and is facing untold charges. Port Alberni RCMP Staff Sgt.
