OSI protocols

Kenneth Hartlaub 1. The Open Systems Interconnection Model (OSI) The Open Systems Interconnection (OSI) model contains seven helpful layers that perform specific services in accordance with their layer. It is a logical model of how network systems communicate to each other in a series of protocols. These layers include the Application layer, the Presentation layer, the Session layer, the Transport layer, the Network layer, the Data Link layer, and the Physical layer. The descriptions of each layer are as follows: Application Layer The seventh or top layer within the OSI model is called the Application layer. The responsibilities of the application layer is to provide network applications access to programs. This layer directs communication…

The Distributed Network Protocol version 3.3 or the DNP 3.3 is a protocol used in the telecommunication between the master station, RTU’s (Remote Telemetry Units) and other Intelligent electronic devices. The DNP 3.0 was introduced to communicate between systems in the electric utility, waste and water, oil and gas and security industries(Clarke, Reynders, & Wright, 2004). Created by Harris controls division for the use in electrical utility industry, the DNP 3.0 was available for the third…

community participation, VAC works on the principle of inclusion (Victorian AIDS Council, 2015) within a social business model. In view of this, it connects with a number of LGBTI social clubs, healthcare service units and businesses which support VAC’s work. The communication protocols used with these external stakeholders include face-to-face meetings, phone calls, emails, sending corporate quarterly newsletters and annual reports, putting auxiliary members on their Boards, nominating liaison…

ANSI 8. The TCP/IP and OSI models have some obvious differences, like the number of layers. Think about the more commonly used version of the TCP/IP model discussed in this chapter, and then think about how to talk about TCP/IP using OSI terms. Which of the following is a correctly phrased statement for how to use OSI terminology? a. HTTP is a Layer 5 protocol. b. IP is a network layer protocol. c. TCP is a Layer 2 protocol. d. Leased lines are Layer 7 standards. 10. Which…

TCP/IP Model - TCP and IP stand for Transmission Control Protocol and Internet Protocol this network model has only four layers these are the application layer, the transport layer, the internet layer and the network access layer. These two protocols are used on the internet all the time for transporting data to allow communication to others on the internet and so on with TCP/IP instead of having separate layers for the presentation layer and the session layer instead it is combined into the…

devices and applications to communicate with each other, they must follow protocols and specific rules that are laid out by the Open System Interconnection (OSI) and Transmission Control Protocol/Internet Protocol (TCP/IP) model. In order for data to travel from one device to another, seven layers were created for the OSI & TCP/IP model. These seven layers are a basic standard, utilized by most networks today and are based on the OSI. Even though the OSI model is standard and widely used, it…

Networking P1: DESCRIBE THE TYPES OF NETWORKS AVAILABLE AND HOW THEY RELATE TO PARTICULAR NETWORK STANDARDS AND PROTOCOLS There are many types of wireless networks available. This includes: WAN, LAN, MAN, PAN, WLAN. Below, I will go into detail about each type that will help you understand exactly what each type of network is and what it consists of. What is WAN? WAN or also known as a Wide Area Network is a network that consists of many Networks that are a part of other LAN networks that swaps…

‘Public health is everyone’s business’ illustrates Jones (2012, p.2). The Faculty of Public Health regard public health as a combination of health protection, health advancement and promoting health (Griffiths and Dark, 2006 cited in Jones p.6 2012). For part 1 of this assignment, public health in context aims to set the scene and illustrate the challenges. Health inequalities arising in society will be addresed and critically evaluated using the Marmot Review and the associated policy…

has defined layers called physical (PHY) and medium access control (MAC). Physical layer Clear channel assessment (CCA) within the current channel, activation and deactivation of radio transceiver, data transmission and reception are the tasks that is done by the physical layer. There are different physical layers. The choice of physical layer depends on the applications. The different physical layers are: Narrow Band (NB), Human Body Communication (HBC) and Ultra Wide Band (UWB). NB physical…

The Quotient Ring Transform is an alternate encoding and decoding process developed by Dr. Anna Johnston [5]. The utility of this error detection and correction process is that it is not dependent on a fixed set of primitive roots. Thus, a standard encryption procedure can be efficiently included in the process. This section lays out Dr. Johnston’s work and provides a simple worked example. 3.1 The Chinese Remainder Theorem Recall the standard statement of the Chinese Remainder Theorem [1]:…
