...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 forward...

...performance and reducing the cost of operations in the hospital. Network Overview A review of Patton Fuller’s network reveals that the network is set up in a bus topology, which is the oldest topology. All stations are attached via cable taps or connections to a single length of cable—a wire with two open ends that are terminated by a resistor. The single cable is referred to as a trunk, backbone, or segment (Goleniewski, 2007). There are many different departments in the hospital: Administration, Radiology, RIS data center, and OR/ICU. The backbone network structure for the entire hospital is 1000 BaseT with all station connect using twisted pair concept. Individual sections of departmental networks such as Radiology use different standards such as 1000 BaseF (Apollo, 2013). Network Characteristics & Components The IT data center houses the hospital HIS system. There are three servers in the data center: A Windows exchange server, Internet server, and a RAS server. All three servers are IBM...

...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.

...|Cloud Computing | Corporate Memo To, The Executive Committee Sub: Cloud Computing Arrival The cloud is here, but better exploitation of cloud computing will require improving IT cost transparency management practices to prevent overspending on IT, manage decentralized IT spending, and enable sustainable shared IT service organizations. There is considerable ambiguity in many enterprises about how to financially approach the cloud at the highest levels within IT and in corporate finance. In its various forms, cloud computing has the potential to radically change the way IT organizations budget, fund, charge back and manage IT spending and staff. From an economic perspective, cloud computing is a direct response to an IT marketplace that is addicted to "speed and quality" in enterprises that need a shift in focus to "cost and business value." Because the expectations of IT services have not been managed well throughout the years, there is now a gap between internal client expectations for service levels and the ability of enterprises to pay for this level of service. For 2011, the worldwide market forecast for public cloud is estimated at $89 billion, with a five-year compound annual growth rate (CAGR) of 19%. Compared to the forecast for all IT marketplaces in 2011 of $2.6 trillion, cloud represents only 3.5% of the IT marketplace...

...As per the requirement, we are going to use the Cisco 4300 Video Surveillance model camera in here. So we have to have a good reliable switching architecture for getting the maximum throughput from these cameras. Otherwise they are acting as just ordinary video camera. When we are speaking about the switching architecture of this project, first of all we have to fulfill some major requirements. They are, 1. Must comply with the Cisco hierarchical design model; 2. Must provide physical, as well as logical, redundancy; 3. Must integrate 1Gb uplinks; 4. Must segment camera IP traffic from the existing network for security reasons; 5. Must support a minimum of 150 cameras; 6. Must utilize PoE for cameras to avoid the use of power bricks or power injectors; 7. Must provide sufficient bandwidth for full HD support; and 8. Must minimize rack space. First of all we’ll discuss about the Cisco hierarchical design model. The Cisco hierarchical design model is a three-tiered or layered network model that is used to design and engineer data communication networks. These three tires are, • Access layer - The access layer interfaces with end devices, such as PCs, printers, and IP phones, to provide access to the rest of the network. The main purpose of the access layer is to provide a means of connecting devices to the network and controlling which devices are allowed to communicate on the network. • Distribution layer - The distribution layer aggregates the data received from the...
