Patton-Fuller Community Hospital Networking Project Identify How Data Is Transmitted

Patton Fuller is a community hospital that has been proudly serving the community since 1975. Patience care is number one, and they thrive to ensure each of their patients experience is as pleasant as possible. Hospitals are under enormous pressure to treat patients in the most effective and efficient way. By leveraging the best IT systems, health organizations provide the type of patient care with the speed and efficiency required by the market. By analyzing Patton Fuller’s IT infrastructure, a determination can be made about the network and the devices supported on it as well. The outcome of the analysis will be used to recommend new

1. Application (in terms of cabling infrastructure): The application layer is the OSI layer closest to the end user, which means both the OSI application layer and the user interact directly with the software application. When determining resource availability, the application layer must decide whether sufficient network or the requested communication exists.. (OSI_model#Layer_7:_application_layer)

Layer 4: Transport - This layer maintains flow control of data and provides for error checking and recovery of data between the devices.

The internet layer is built up of four core protocols: IP, IGMP, ICMP and ARP. Internet protocol (IP) is responsible for routing, IP addressing and breakdown/reassembly of data packets, address resolution protocol (ARP) is responsible for mapping an IP address to a device on the local network, internet control message protocol (ICMP) provides diagnostic information and error reports on lost packets, internet group management protocol (IGMP) controls who receives IP datagrams in a single transmission. The transport layer is built up of two core protocols: TCP and UDP. Transmission control protocol (TCP) sequences and acknowledges packets sent and their recovery when lost in transmission allowing the computer to make and maintain network conversations where applications exchange data, defined as a connection-oriented protocol meaning the connection is maintained until the programs has finished exchanging data. User datagram protocol (UDP) This is used to transfer small amounts of data when the use of error correction isn’t needed increasing the speed of the transmission, common in multi-player video games as the user will not need to receive packets of past events in the game so the error correction featured in (TCP) would be

Layer 4 is the transport layer and utilises common transport protocols to enable network communications. This may include the Transport Control Protocol (TCP) and Universal Data Protocol

The first three layers of the OSI is typically what a router needs to route traffic. The first three layer are physical, data link and network. The highest level the OSI decide where to forward traffic to is the transport layer which is located in the host layers.

1. The device layer is responsible for communicating with a specific subsystem’s devices.It is present in every

The fifth layer is the session layer this establishes a connection,this layer makes and sets up the connection using co ordinates and could terminate conversations links. the session layer produces services that make authentication after an interruption and not only that but it can reconnect.and as well as the transporting layer it can also have the TCP and the UDP can provide services for all most all applications.An application layer is an abstraction layer that specifies the shared protocols and interface methods used by hosts in a communications network. The application layer abstraction is used in both of the standard models of computer networking; the Internet Protocol Suite (TCP/IP) and the Open Systems Interconnection model (OSI model).Although both models use the same term for their respective highest level layer, the detailed definitions and purposes are different.In TCP/IP, the application layer contains the communications protocols and interface methods used in process-to-process communications

It is operating on best effort delivery model, i.e. it does not guarantee delivery, nor does it assure proper sequencing or avoidance of duplicate delivery. These aspects, including data integrity, are addressed by an upper layer transport protocol, such as the Transmission

gateway. When the data packets reach their destination, they fit back together to for the

Patton-Fuller Community Hospital has been in business in the City of Kelsey since 1975. The hospital provides high quality medical care to the citizens of Kelsey and the surrounding area. Some of the services the hospital offers are x-rays, pharmacy, and emergency services for children and adults. “As one of the first hospitals in Kelsey, the staff is committed to providing a variety of programs that will support the health and welfare of the local community populations” (Apollo Group, 2010).

3: Network Layer: The use of network layer is switching and routing technologies. It demonstrates logical path and virtual circuits for transferring data from one node to

Which layer of the OSI reference model handles logical addressing (IP addresses) and routing traffic?

A given layer in the OSI model generally communicates with three other OSI layers: the layer directly above it, the layer directly below it, and its peer layer in other networked computer systems. The data link layer in System A, for example, communicates with the network layer of System A, the physical layer of System A, and the data link layer in System B. The following figure illustrates this example.

The physical layer specifics the function details for initiating, keeping up and turning off the physical link when moving the bits of data over the physical media such as copper, fibre or wireless. So it will takes your data bits of ones and zeros covert them to what is needed to transfer over that type of media so for example change bits into electrical signals for copper cables then will covert it back to ones and zeros once it reaches its destination to send up OSI model layers.
