The RAD tutorials mainly focus on telecommunications, data communications and computer networking. They offer a descriptive approach to the core concepts in the above fields, and can be said to an effective learning tool in a computer networking and data communications class (Bagad 41). The introductory and general tutorial comprises of Client-server, internet communication, the internet protocol model, the internet Resiliency, the OSI reference model and the Regional Internet registries. The paper focuses mainly on the OSI reference model and the Internet protocol model. These were picked because they are all reference models that are used in facilitating data communications. In addition, the two models have various similarities making it a subject of interest as to why the internet protocol model could not just be merged as a part of the OSI reference model (Bansal 47). This paper discusses the business needs that are being addressed and the value that are delivered by them. In addition, the paper provides an evaluation of the tutorial and experience of the tutorials.
The OSI reference is an important aspect of data communications, which is increasingly becoming an important tool for business enterprises in the modern business era. The OSI reference model represents a model of the various protocol layers that are standard approach how data communications work and are taught irrespective of the fact that they do not practically represent the functionality of the protocols that are used in internetworking. The purposes of the seven layers of the OSI reference model are arguably present in the various communication scenarios that are deployed currently, however, only a protocol stack comprising of five layers are used for accomplishing the data communication functions. There is a significant correlation between the protocol stacks that are represented in the OSI reference model and the Internet Protocol Model. Basing on the Internet Protocol model, it is more logical to include a protocol stack under the Internet Protocol although on top of the infrastructure, which mainly comprises of the data link and physical layers. As a result, the protocol stack that is intermediary is normally referred to as the Network interface layer, which basically describes the functionality of the Internet Protocol in accordance with a specific infrastructure. Therefore, the internet protocol model comprises of the application, transport, IP/ network, network interface and the infrastructure layer (Bansal 78).
It is important to note data communications primarily depends on the OSI reference model and the Internet protocol model, implying that they are core in the achieving business goals that are directly related to data communications. Data communications is becoming an important tool that business organizations are relying on to facilitate the execution of organizational processes. In addition, communication processes in the company and facilitate management processes through the use frameworks such as the company intranet. Connectivity to the internet comes with added advantages through which the company can communicate with the outside world (Bansal 78).
Working with the tutorials are an excellent experience owing to the fact they contributes to one’s understanding of the telecommunications, computer networks and data communication. The tutorials offer adequate information regarding the various fields. In addition, the introductory and general tutorial helps in the adding of one’s professional resources concerning the aspect of data communications, computer networks and telecommunications. Basically, the tutorials are an important tool for IT professionals and students.
