Nt1310 Unit 1 Assignment

There are seven layers in the OSI model. Each layer has a function or purpose that is used to set up a network. The International Organization for Standardization began to develop the OSI framework in 1984. The purpose was to have each layer interact with the layer directly beneath it. The layers are starting from the top: Application, Presentation, Session, Transport, Network, Data Link and Physical. The Application layer has the function of providing interface between software applications and network for interpreting the requests and requirements for applications. “This top layer defines the language and syntax

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).

I face a number of unusual personal expenses that make it difficult for my family to contribute to the cost of my education. Unfortunately, I along with my two other siblings and mother have been diagnosed with a variety of autoimmune diseases. I have been diagnosed with Type One Juvenile Diabetes, my middle sister has been diagnosed Vitiligo, my youngest sister has a form of Uveitis, and my mother has been diagnosed with Rheumatoid Arthritis. In order to treat our respective diseases we need to take the prescribed medications that are each very costly and do not have a generic brand available on the pharmaceutical market. The treatment of my, my siblings, and mother’s collective diseases is financially heavy on our family, and it makes it

Before starting my day, I usually put on a earphone and press “shuffle play” on my Throwback playlist on my Spotify account. The most recent five songs that I have listened to before writing this assignment was You Rock My World - With intro by Michael Jackson, Baby, I’m Back by Baby Bash, Just The Two Of Us by Grover Washington, Charlene by Anthony Hamilton, and Show Me The Way by Earth Wind & Fire. Interestingly I have never heard these songs until last year because I was only exposed to music that was on the radio station such as 94.9 or 106.1 where newest and trending songs were played most often. Since three of those songs were produced in early 2000’s and the other two produced between the 1970s and 1980s, I was never able to come across

I have always been the person people go to for answers. Since seventh grade I have been in honors classes; I was the only seventh grader in an eighth grade math class. I had never been so nervous walking in to class in my life. My legs were trembling and my hands were shaking. I walked around the room hoping to find a seat not in the back so I do not show my teacher I do not care; but not in the front so my classmates think I am a kiss up. I sat in between two boys, and tried to not let them see how intimidated I actually am by them.

Understanding the way A.I. works is crucial to understanding A.I. goals. There are several traits that separate Artificial Intelligence from regular machines. One such trait is an A.I.’s ability to “think” through Neural Networks, which are networks made of simulated neurons and neuron layers designed to process and evaluate data. The simulated neurons are individual receptors designed to process and evaluate inputs. Following their evaluation, the neurons send an output to another simulated neuron in the next neuron layer. These neuron layers are layers of simulated neurons grouped by what type of input they receive and output they produce, that scales in complexity (Knight). MIT tech review senior editor Will Kight provided the example of

When the class was asked to read the story silently to themselves, T was only able to do this for a few minutes before his attention was focused on something else. In the book, it says, “attention is essential to the learning process” (Mcdevitt & Ormrod, 2013, p.240) T loses attention quickly when he is asked to do something on his own. When he loses attention I wonder if his learning process is being hindered because of this?

2. The OSI model is not directly implemented in networking and often the distinction between the layers will blur in implementation. Why does it endure despite these

The layer starts from 7 being the top layer and 1 being the lowest layer of the OSI model. Application layer- Serves as the window for users and application processes to access networks services like web browser (Internet explorer, Mozilla) protocols – DNS & SSH etc. Presentation layer- Translates data from the format send into the format that program can understand. Session Layer- Starts and end session and also keeps them isolated protocols- SMB,NFS, Socks and allows session establishment between processes running on different stations. Network- Determines addressing method for being transmitted. Transport- Defines ports and reliability protocols- TCP, UDP. Network- logical or IP addressing: Determines best path for the destination protocols- IPV4, IPV6, ICMP, IPsec. Data link- Contain data into a frame that contains a header with a destination. Switches, Mac addressing protocols- PPTP, Token Ring. Physical Link- Determines the hardware used and the method used for data transmission like cables, network interface cards, electrical

2. The seven Layers in the OSI model are Physical Layer, Link Layer, Network Layer, Transport Layer, Session Layer, Application Layer and the presentation Layer. Each layer has a specific function to perform and consist of different protocols. Physical layer is the lowest one and handles transmission and reception of messages over the medium. Then comes the link layer , it allows error free transmission of the data frames in the physical layer. The network layer takes care of processes like routing, traffic control and fragmentation of the data. The next one is the transport layer, it takes care of the

The third layer of the OSI model is the network layer. This layer is responsible for end to end packet delivery. The network layer issues request to the data link layer and responds to requests from the transport layer and issues requests to the data link layer. The procedural and functional process of sending different

A model that was use to understand and develop computer-computer communications over network is known as OSI (Open Systems Interconnection) which is a model that divides network communication into seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application. At each layer, protocols perform services

The network services, made available by this layer, are utilized by users and application programs. It basically acts as a window between network services and users & application processes. This layer also handles functions like - Resource sharing and device redirection, Remote file access, Remote printer access, Inter – process communication, Network management, Directory services, Electronic messaging and Network virtual terminals.

The Open System Interconnection (OSI) reference model describes how information from a software application on one computer moves through the Internet network to a softwork application another computer.
