Nt1310 Unit 3 Assignment 1 Network Analysis

Once one of the computers is properly configured as a file server, users can access the storage by mapping the drives on the respective computers. The file server will be mapped as a drive and users can store, edit and access files directly from the shared storage disk. The disk will be connected to each computer. For example, when a user needs to access any file from the file server, he/she can access the drive that will now be mapped on the every computer (Science - Opposing Views, 2014).

A: LAN: LAN stands for Local Area Network. LAN is a network which cover a small area like colleges, schools or buildings.

Layer 5: Session - Layer 5 establishes, maintains and ends communication with the receiving device.

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).

A LAN is a ‘Local Area Network’. It is a small network of computers most often

Files are stored at server disk. Clients do read and write operations on the network.

The OSI (Open System Interconnection) model is a set of specifications that allow computers around the world to openly communicate. It is pivotal to understanding and developing computer to computer communications in a network. Each layer plays a role in the process of sending and receiving data. The application layer is the top layer (layer seven) it promotes communication between programs and lower-layer network services. The services at this layer allow the network to decipher a program's request and the program to decipher data sent from the network. The Application layer protocols, programs handles formatting, procedure, security, synchronization, and any other requirements with the network. The Presentation Layer (layer 6) acts as a translator. For instance these protocols decode the jpg/jpeg files sent within the Web server’s HTTP response. So, in the last step (the Application layer) we enter the Web address and it took us to the Web site. This step allows us to see the images and content of the site. The Session Layer (layer 5) regulates and controls the communication between two nodes on the network. It is an ongoing exchange of data between the two and keeps the connection between them for the duration. It keeps the communication secure, detects whether or not the communication has been cut off and if it has it determines where to restart the

Compared with the single-owner manner, where only the group manager can store andmodify data in the cloud, the multiple-owner manner is moreflexible in practical applications. More concretely, each userin the group is able to not only read data, but also modify his/her part of data in the entire data file shared by the

It is generally limited to a geographic area such as a writing lab, school, or building. Rarely are LAN computers more than a mile apart. In a typical LAN configuration, one computer is designated as the file server. It stores all of the software that controls the network, as well as the software that can be shared by the computers attached to the network. Computers connected to the file server are called workstations. The workstations can be less powerful than the file server, and they may have additional software on their hard drives. On many LANs, cables are used to connect the network interface cards in each computer; other LANs may be wireless.

Core The core layer is the backbone layer of the network running at high speed switching, transferring large amounts of data and also handling the requests of the distribution layer . This layer has high speed devices; the most implementations have layer 3 switches or high end routers. Its key characteristics are: redundancy, fast transport of large amounts of data, high reliability and availability, low latency. The core layer should not do any packet manipulation.

Most companies now provide a software that allows users to share files. They share by downloading directly off of another user's hard drive (Auster).

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.

A LAN is a network of computers in a specific area interconnect using a variety of network media. For example, WBHS LAN are all the computers connected to the WBHS network via Ethernet, Wi-fi or other. This is different from a WAN (Wide area network) which extends to a much wider area such as a town, city and country. LAN are usually more restricted in access and more numerous.

Users 2 to 15 have access to their individual folders where they can they can read, delete, write and amend files. The files in the folders belonging to the other users can only be accessed and copied but not modified.
