3-Describe wired LAN, its purpose, basic configuration, and supported standards. Specifically explain the VLAN concept and its use within the wired LAN infrastructure. What healthcare use can you envision for wired LAN? If unsure, search the literature for answers. A wired LAN connects computers within an organization in a network configuration and each PC on the LAN must connect to the network with a network interface card (NIC). The NIC needed varies by which cabling is used for the network (Cowley, 2012). NICs help to direct traffic on the network if a shared medium is used and they also help detect transmission errors (Cowley, 2012). Wired LANs can be complex and expensive to configure in an institution; some equipment needed for a wired LAN include hubs, switches, and routers. The hub, which is an OSI Level 1 device, acts as a signal booster within the LAN. Switches are OSI Level 2 devices and are actually intelligent devices that understand the addresses, connect different LAN segments, increase the bandwidth on the LAN, and are needed to create virtual LANs (VLANs) (Cowley, 2012; Morency, 1995). The wired LAN needs a dedicated location in a closet to house the patch panel/switchboard that connects all the wires from all the PCs on the network as well as the server. The equipment …show more content…
For example, Children’s Hospital in Boston moved all the servers that were on their wired LAN to a central location and began utilizing VLANs throughout the hospital. This reduced the need for distance cabling throughout the hospital which in turn reduced costs, as well as allowed for better server maintenance and monitoring since all the servers were in one location (Morency, 1995). VLANs can allow smaller IT departments to use their resources more efficiently and this is especially important for smaller health care organizations (HCOs) who may be struggling

    Harris Memorial Hospital Case Study

    Your healthcare organization, Harris Memorial Hospital, needs to look at both “hard” and “soft” savings when considering a system’s return on investment. Today’s presentation we will take a deeper look at the soft returns when implementing an electronic health record (EHR) system. It is important to remember that indirect savings are usually applied to processes not easily measured and, thus, quantifying savings can be difficult to see at first. We will look at the three steps in documenting soft returns: (1) identifying a process improvement opportunity, which is improved time/efficiency; (2) create a formula to calculate the benefits; (3) and determine the costs of the process and the net benefits. In order to determine the return benefits from EHR implementation, it is necessary to establish baseline metrics that can be used as a guideline for measuring success after the implementation.…

    Algorithm: Exponential Growth Of The Internet And The World Wide Web

    The Internet was originally called the ARPANET, and in order to enhance the ARPANET to be enable may different types of computer networks to all communicate with each other, an open source protocol needed to be created, hence the development of TCP/IP. TCP/IP improved communications throughout the network and allowed all computers to easily communicate with one another. Another technology that helped expand the ARPANET to more users in a specific location was the development of the Ethernet. Ethernet is a coaxial cable that is still used today in many local area networks. Ethernet is highly effective in moving data from one computer to another at high speeds.…
