OSI Model Analogy Trevor Crews Strayer University The OSI model is the model developed for computer-to-computer communications over a network. This model breaks down all the functions that occur into seven distinct layers. These layers are‚ application‚ presentation‚ session‚ transport‚ network‚ data link‚ and the physical layer. Each one encompasses a specific part of the process that occurs during the communication. In order to simplify this think of it like sending a package through the
Free OSI model OSI protocols
The OSI model has seven layers‚ with each having different types of security responsibilities. The seven layers are application‚ presentation‚ session‚ transport‚ network‚ datalink and physical with control being passed down from layer to layer starting with application. The biggest threat to these layers is through people‚ sometimes known as the 8th layer of the OSI model. Companies should take the time to educate their employees on the security threats that each individual brings to the company

The OSI model is a protocol stack where the lower layers deal primarily

popularity of TCP/IP? The factors that account for the success and popularity of TCP/IP are integrated addressing system‚ design for routing‚ underlying network independence‚ scalability‚ open standards and development process‚ and university. TCP/IP includes within it a system for identifying and addressing devices on both small and large networks. Unlike some network layer protocols‚ TCP/IP is specifically designed to facilitate the routing of info over a network of arbitrary complexity. TCP/IP operates

The goal of congestion control is to avoid congestion in network elements. A network element is congested if it is being offered more traffic than it can process. To detect such situations and to neutralize them we should monitor traffic

OSI in China: Pre-assignment If I were Stefan‚ I would choose to export the parts of the chicken that is not sold to OSI’s customers in China. I will go through each of the proposed options and share my thoughts on why it may or may not be a good choice. 1. Expand sales to current customers The only way to expand sales to the current customer base is to successfully come up with new processed items that QSRs’ customers will want to buy.

Reginald Monroe-@02516632 Summary of OSI layers & Security OSI stands for Open Systems Interconnection and it was developed by the Europeans in the 1980’s. OSI is divided into two major fields‚ an abstract model of networking and a set of defined protocols. The seven layers of the OSI basic reference model are listed and defined below (from bottom to top): 1. The Physical Layer – this layer describes the physical components of the various communications media‚ it also includes the electrical

OSI in China: Pre-assignment OSI China is a difficult situation because they have already invested a large amount of capital‚ time and are currently left with 80% of the chicken after vertical integration. All four options to consider are mixed with unpredictable outcome regardless of the option and will depend heavily on the company’s capabilities and resources. Since 80% of the chicken is currently available for sale with no demand from Chinese customers one of the solutions OSI can consider

Transmission Control Protocol (TCP). Looking at UDP this protocol is unreliable and does not create a connection to the summoning application. TCP however does provide a reliable connection. This protocol also has an added bonus where any errors that are found during transmission will be retransmitted‚ which means that this protocol endeavours to make error checks (Kurose J‚ Ross K‚ 2013). Most of the traffic that is carried over the internet however utilises the TCP (Ostrowsky et al‚ 2012). RealNetworks
