information. The National Health Information Network (NHIN) was formed to help improve upon the sharing of health care data. This was to help link data together for all involved to keep data secure when transferring over the internet. Within a health care organization a Hierarchy information system is used. This offers ease of network expansion and alteration for desktops used to be able to access necessary data. Both local area network (LAN) and wide area network (WAN) are used in within the organization
