to send a message to the host detailing what kind of error it encountered. Jessica Fitzgerald, J., Dennis, A., & Durcikova, A. (2015). Business Data Communications and Networking. Wiley & Sons. IP Addresses Joseph Office 9/12/2016 5:02:19 AM Internet Protocol (IP) addresses are essential in order to determine key characteristics of the destination for information packets. It is a map or guide for vehicles (information packets) to get their destinations (networks and hosts) along the information superhighway. IP addresses consist of multiple identifying parts: They consist of a 32 bit number of which a portion identifies the host network, the specific host (computer, printer, etc.), and subnet mask. The subnet mask is used to determine whether a particular host resides in a local or remote network. Network and Transport Layer Samuel Amadasun 9/12/2016 7:16:11 AM The network and transport layer are identical in many ways according to our text. The transport layer basically is the link between the application layer and the network layer and is responsible for the segmentation and delivery of messages. The network layer is basically responsible for taking the messages from the transport layer and finding the right path to transmit the messages through networks. An IP packet is added in the network layer and stands for internet protocol. IP is one of many protocols and is the transport/network layer protocol used on the internet. It is also reasonably efficient, error­free during transmissions, and compatible with a variety of data link protocols (FitzGerald, 116). my understanding of internet protocol is that it is responsible for everything we send over the internet. So, for example, emails to other computers or links to websites are all transmitted using IP. FitzGerald, J., Dennis, A., & Durcikova, A. (n.d.). Business Data Communications and Networking. Retrieved September 12, 2016. Network Design Karly Derosena 9/12/2016 11:55:29 AM OSI (Open Systems Interconnection) is reference model for how applications can communicate over a network. A reference model is a conceptual framework for understanding relationships.In the Open Systems Interconnection (OSI) communications model, the Network layer knows the address of the neighboring nodes in the network, packages output with the correct network address information, selects routes and quality of service, and recognizes and forwards to the Transport layer incoming messages for local host domains.It is the third layer, situated in between transport layer and data­link layer.The network layer is the third level of the Open Systems Interconnection Model (OSI Model) and the layer that provides data routing paths for network communication. Data is transferred in the form of packets via logical network paths in an ordered format controlled by the network layer. The main aim of
