1. The type of network to be used
Networks can be classified as either local area networks or wide areas networks. The company decided to use Local area Network (LAN) since several computers; peripheral device and server are connected together by cable within the factory. ÐŽ§Communications networks are a collection of terminals, computers and other equipment that used communications channels to share data, information, hardware, and software; to enhance communication within an organization.ÐŽÐ (Establishing a computer network, 2005) Since there is currently only one manufacturing plant and the company required high up time. Reasonable assurance is needed that the information system will not break down and stall the manufacturing process. According to the definition, ÐŽ§The common applications of local area networks are hardware, resource sharing, software resources sharing and information resource sharing.ÐŽÐ (Establishing a computer network, 2005)The local area networks are enough to use on track of customer orders to process them in an efficient way, inventory control, and schedule maintenances and data analysis.
2. The type of topology that best fits the requirements of the company
