Networking - Statistics Project Example Moreover, tree topology facilitates the network administrator to expand the network easily. However, if the network expands, it becomes more difficult for the network engineers to manage the network. 2 Issues of Tree Topology As there is no centralized provision of services, it is difficult for the network engineers to tackle issues related hardware, software and network services. Physical intervention is required as the hub backs up each network segment, if the hub become nonoperational, the workstations of the entire department becomes unavailable on the network. Moreover, it is not necessary that each network segment is using the same cabling scheme (Chapter 5: Topology). Due to compatibility issues, cross cabling or straight cabling is required, consequently making difficult for network engineers to troubleshoot network issues. Moreover, due to separate network segments on the network, some network segments may become vulnerable to threats, as network administrators do not have a centralized access to the network devices. These considerations must be analyzed during the network design stage of an organization. 3 Network Infrastructure Recommended LAN topology is a star topology. As star topology shares many advantages, the most prominent one is the centralized administration and monitoring of the network. Moreover, star topology provides high data speeds along with easy installation of cables. Any component on the network can be removed or plugged in without any interruption. Likewise, centralized administration facilitates network administrators and engineering to detect issues and faulty components. Hubs may deteriorate network performance. As they can only operate on the maximum data transmission speed of 10 Mbps and copy data files to the designated... Recommended LAN topology is a star topology.

Moreover, star topology provides high data speeds along with easy installation of cables. Any component on the network can be removed or plugged in without any interruption. Likewise, centralized administration facilitates network administrators and engineering to detect issues and faulty components. Hubs may deteriorate network performance. As they can only operate on the maximum data transmission speed of 10 Mbps and copy data files to the designated ports, files that are larger will take time and may congest the network. However, cost of the hub is low as compared to a switch; it may affect the performance of the network. On the other hand, switches can improve network performance significantly. As switches can learn the MAC address of the sender, they create a management information base for storing all the MAC addresses of network nodes. This will eliminate the time taken by the switch to identify and learn MAC address of the sender. Moreover, switches can provide the overall network usage along with statistics related to access policies via the network. Switches only share a disadvantage of a high cost as compared to hubs. A simple definition of regenerative repeater is available in network dictionary which states it as â€Å"a device which regenerates incoming digital si gnals and then retransmit these signals on an outgoing circuit†.

See description - Research Paper Example Medicare furnishes healthcare program to help such disadvantaged financial situations of the elderly U.S. residents. The workforce pays taxes to the government throughout the employment period. This accumulated money of the individual in the form of taxes is given back after 65 years of age independent of their current working status. While, the Medicaid delivers healthsecurity net to necessitous and vulnerable population, and are executed by individual State separately. Medicare’s senior enrollee can also be a part of Medicaid. Medicaid enrollees can avail additional cost benefits over Medicare for prescription drugs, diagnostic and preventive care, and eyeglasses (Nolo ®, 2010). The recipients of Medicare and Medicaid can overlap. In such cases, the entitled enrollee of Medicaid offers financial help for Medicare deductibles and the Medicare premium. As the global, political, social and environmental factors are charnging at fast pace, each federal program is facing ongoing challenges.These challenges are carried over and entire health care system is trapped into vicious cycle. Financing of Medicare as well as Medicaid is the most emerging issue due to corollary effect of general aging of society, economic recession, and unemployment. Managed care is the major health service program subsequent to the arrival of Medicare to reduce the cost of health care services for patients. Managed care plans are health insurance plans frequently involves unreasonable limits on visits with health care providers and medical facilities. But it no longer is viewed by most employers and federal and state governments as the primary means by which health care costs can be brought under control due to vested interest of individuals in America’s health care delivery system (Boyle & Callahan, 1995). Managed care system is connected with several legislative acts because of which it drew into controversy to give best service in the interests of patients. The clinicians,
