Three Network Topologies Essay Example | Topics and Well Written Essays - 500 words

Three Network Topologies - Essay Example Here the first topology we use for our company is BUS: The bus topology is frequently referred to as a "linear bus" for the reason that the computers are linked in a straight line. This is the easiest and mainly common technique of networking computer. By this our company’s whole computer is connected to main server so that whole data can be seen on main server.1 Next the second topology we use is STAR: In the star topology, wire sections from every computer are linked to a centralized part that is called a hub. Signals are broadcasted from the transmitting PC throughout the hub to all PCs on the network. This topology invented in the early on days of computing while computers were linked to a centralized mainframe workstation. This topology we use for the connecting the whole organization to our main server. So that any message from any PC can be deliverer to each PC on the network.2 The 3rd topology we use for our company is RING: The ring topology attaches computers on a sole circle of wire. Dissimilar the bus topology, there are no ended ends. The signals tour about the circle in one way and go by from side to side every computer, which be able to take action as a repeater to increase the signal and drive it on to the subsequently computer. The breakdown of one computer can have a crash on the whole network. This topology we use for our company to only in case of transmitting any information that we want to reach on every PC. By this information or any error report can be circulated to whole network.3 Here I will present the performance, reliability, cost and effectiveness criteria of our company for the selection of topology. We avoid using the mesh topology because it is more costly and we have lot of workstation so that we can not afford a very complex net of wires, so these only three topologies that are BUS, RING, and STAR are used by us in our company. The cost of these three for implementing point of view is less than the mesh topology.

Evidence Based - Assignment Example Critical appraisal is currently a key component included in the training and continuing professional development of all health professionals like nurses in various settings (Burls, 2009). Critical appraisal allows a nurse to judge the validity, reliability and applicability of results of any clinical research while applying it to practice (Burls, 2009). This is because, the process includes intrinsic factors of research like study design, methods, results, etc,to analyze the value of the study. Critical appraisal is a very essential component of evidence based practice which is gaining momentum. The process of critical appraisal involves identifying the appropriateness of the study for the purpose of evidence based practice, ascertaining whether the studies have been conducted in a way which makes the results sensible, making sense of the results by analyzing the methodology of analysis and also understanding the meaning of the results in the context of decision making (Burls, 2009). One of the main challenges to implementation of critical appraisal for evidence based practice is lack of evidence seeking behaviour amongst many clinicians, poor attitude towards evidence based practice, need for appropriate technical knowledge of research design and statistics which are difficult to acquire and lack of time (Brice and Booth, 2005).
