Vocabulary Exercise: Matching

A: OSI stands for Open System Interconnection. The main aim of the OSI layer is to implement protocols of a networking framework.

The most common type of network and the frames that come with it is Institute of Electrical and Electronics Engineers (IEEE), also known as:

2. Enterprise networks typically use LAN _____ at each site to connect devices using some type of media.

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)

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

d) The information is acquired on the data bus and send it to TDO. (Alghafli, Jones, and Martin. 2012).

As we all know, the growth of computer networks continues to rapidly grow. The digital revolution has changed the way we work and communicate almost beyond recognition. Provided that, foreseeing the changes and potential compatibility problems, in the mid nineteen eighties, the international standard organization (ISO) developed a networking reference model to standardize how network systems communicate with each other. It is a logical model for how network systems are supposed to communicate with each other. It breaks down the different components of the network communication and puts them into layers which reduce complexity. This reference model consists of seven layers: Application Layer, Presentation Layer, Session Layer, Transport Layer, Network Layer, Data Link Layer, and the Physical Layer. Each layer provides a service to the layer above it in the protocol specification and then communicates with the same layer’s software or hardware on other computers. It's important to realize, that these layers are separated into 2 sets: Transportation Set (Laters 1- 4) and Application Set (Layers 5 – 7). More importantly, the OSI model is 7 logical

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

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

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.

As the data packet moves from the upper to the lower layers, headers are _______.

Transmission Path Level: This extends between network elements that assemble and disassemble the payload of a transmission system. For end-to-end communication, the payload is end-user information. For user-to-network communication, the payload may be call-control signaling information (call setup and call termination). Cell delineation and header error-control functions are required at the end points of each transmission path.
