Cisco Feasibility Study
Computer shop course is the one of the most demand business present in the Stop. Ion Patters Tagging City, internet cafes atomic number 18 re eithery in demand because of the fast changing technology that the people embarrassed Just like here in the Philippines. Some have their own laptops and bring it to the malls so they could relax and at the same time prepare their assignments and paper works.The people today are very ND would want to do their Jobs in the beautiful innovative environment that could satisfy their needs and lessen their stress due to busy record OBJECTIVES/GOAL -To earn profit. -To satisfy costumers providing best musical note services at effective price. -Providing the services at low cost by providing the best quality at affordable price. -To achieve its return of investment and the business giving satisfaction to the owner. VI. Technical Feasibility vii-l Location b. Floor Plan Star lucre Star networks are one of the most common computer network topologies .In its implies form, a star network consists of one exchange switch, hub or computer, which act as a conduit to transmit messages. This consists of a central node, to which all other nodes are connected this central node provides a common connection point for all nodes through a hub. In star topographic anatomy, every node (computer workstation or each other peripheral) is connected to a central node called a hub or switch. The switch is the server and the peripherals are the clients Thus, the hub and leaf nodes, and the transmission lines between them, form a graph with the topology of a star.If the central node is passive, the originating node mustiness be able to tolerate the reception of an echo of its own transmission, cargo decked by the two-way transmission time (I. E. To and from the central node) plus whatsoever delay generated in the central node. An active star network has an active central node that usually has the means to prevent echo-related problems. Advantages Better performance star topology prevents the passing of data packets through an excessive number of nodes.At most, 3 devices and 2 links are involved in any communication between any two devices. Although this topology places a huge overhead on the central hub, with adequate capacity, the hub very high utilization by one device without impact others. Isolation of devices Each device is inherently isolated by the link that connects it to the hub. This makes the isolation of individual devices straightforward and amounts to disconnecting each device from the others. This isolation also prevents any non- centralized failure from affecting the network.Benefits from centralization As the central hub is the bottleneck, increasing its opacity, or connecting additional devices to it, increases the size of the network very easily. Centralization also allows the direction of traffic through the network. This facilitates analysis of the traffic and detection of suspicious behavior. Easy to detect faults and to remove parts. No disruptions to the network when connecting or removing devices. Installation and configuration is slow since every one device only requires a link and one input/output port to connect it to any other device(s).Disadvantages Failure of the central hub renders the network inoperable Communication between nodes must pass through the central hub. Therefore if the central hub is compromised, so is all communication. The hub is the bottleneck for throughput as it is required to retransmit the sum of all transmitted messages from devices.
