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

2: Data Link Layer: It take care of errors in physical layer. The main aim of the data link layer is to controls the flow of frame synchronization and transmission protocol. The data link layer divided in to two types. They are Media Access Control (MAC) and Logical Link Control (LLC).

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

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

• “Application - The Application Layer is the layer that most network users are exposed to, and is the level at which human communication happens. HTTP, FTP, and SMTP are examples of the application layer protocols the Patton-Fuller will now be utilizing for communicating electronically” (Network Design, 2012).

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)

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

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

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).

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

Layer 3 is the network layer and utilises multiple common protocols to perform routing on the network. Protocols consist of the Internet Protocol (IP), packet sniffing and DoS attacks such as Ping floods and ICMP attacks. Because of their layer 3 nature, these types of attacks can be performed remotely over the Internet while layer 2 attacks primarily come from the internal LAN.

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

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

* When it comes to routing, the network layer; is what finds the data link layer address of the next corresponding computer that the message has to be sent to. The easiest way to interpret this, is to look at it with Ethernet software. For example, if the data link layer is run using Ethernet, the network layer IP address would have to be translated into an Ethernet address so they can match and understand each other. Ethernet addresses are six bytes in length. The following table below, shows a better picture of the differences in software and addresses amongst the three. (Fitzgerald, 158)

The application layer: this layer allows different applications to communicate with each other’s. In order to exchange different data over the network connection, the protocols included in this layer set up the standards such as DNS, HTTP, FTP. The data coded in this layer will be encapsulated to transport layer for further packing.

The data link layer is responsible for controlling access to the media and formatting the data for transmission for going across the physical network link. So it encapsulates the packets from the network layer to suitable frames for the network media to use for transferring data frames from one place to another error free. The addressing used at this layer is physical addressing also known as mac addressing which is how devices are addressed at this layer instead of IP addressing. The data link layer also does error detection at this layer as well.
