Introduction
As technology continues to evolve and become more complex, it’s important for management teams to understand the basic fundamentals that make it all work. One of the most important aspects of any computer network is the communication process, which is why it is crucial to understand the OSI model and the TCP/IP suite (Alani, 2014). While these terms may sound like gibberish to some, they play a vital role in ensuring the smooth and efficient operation of any computer network. In short, the OSI model and TCP/IP suite are two different ways of organizing the various protocols that allow devices to communicate with one another.

Explain the differences between the OSI model and the TCP/IP suite in terms the management team can understand. What is the purpose of each model?
The OSI model (Open Systems Interconnection) is a conceptual model that was developed in the 1980s by the International Organization for Standardization (ISO), and the TCP/IP suite (Transmission Control Protocol/Internet Protocol) is a protocol suite that was developed by the U.S. Department of Defense and its contractors in the 1970s. While both models are designed to help computers communicate with each other, they approach the problem from different perspectives. The OSI model has seven layers, each of which has a specific function that helps to facilitate communication between different computer systems. The top three layers deal with the application (such as web browsing), presentation (such as data formatting), and session (such as managing a connection between devices). The remaining layers deal with lower-level functions such as the physical transmission of data over the network (Li et al., 2011). On the other hand, the TCP/IP suite is a simpler protocol suite that consists of four layers. These layers include the application layer (which handles tasks such as file transfer and email), the transport layer (which manages data
Which between the OSI model and the TCP/IP one might be described as a reference model and which one as an implementation model and why?
The OSI model and TCP/IP suite are both important for understanding how data is transmitted over a network. The OSI model, developed by the International Organization for Standardization, is often described as a reference model, as it provides a framework for understanding how different network protocols communicate with each other. In contrast, the TCP/IP suite is often described as an implementation model, as it provides a specific set of protocols for transmitting data over a network. The purpose of the OSI model is to provide a theoretical framework for understanding network communication, while the purpose of TCP/IP is to provide practical protocols for implementing network communication. While both models are important for understanding network communication, the OSI model is often used as a teaching tool, while TCP/IP is used in practical applications (Van Der Schaar & N, 2005) . It is important for members of the management team to understand the differences between these models, as they play a crucial role in the development and implementation of network infrastructure.
What is the purpose of the layer concept? Give me two good examples of applications associated with the OSI application layer.
The layer concept is a fundamental concept in networking that helps to organize and structure communication between various devices. The purpose of the layer concept is to separate the various functions of network communications into distinct layers, with each layer responsible for a specific set of tasks (Weinhardt et al., 2009). This separation helps to simplify network communication and make it more efficient. By breaking down the communication process into smaller, more manageable tasks, each layer can focus on its specific role and work more effectively.
The OSI (Open Systems Interconnection) model and the TCP/IP (Transmission Control Protocol/Internet Protocol) suite are both foundational networking models that are widely used in the industry. The OSI model is a theoretical and conceptual model that describes how data should be transmitted over a network while the TCP/IP suite is a practical implementation of the OSI model that is used to connect devices over the Internet (Van Der Schaar & N, 2005). The OSI application layer is the topmost layer of the model that enables communication between different applications on different devices. Two good examples of applications associated with the OSI application layer are email and file transfer protocol (FTP). Email uses the Simple Mail Transfer Protocol (SMTP) to send and receive messages while FTP uses the File Transfer Protocol (FTP) to transfer files between systems. Overall, the OSI model serves as a standard reference model for understanding network communications while the TCP/IP suite serves as a practical tool for connecting networks and devices on the Internet.
Why has the cloud concept become so popular? Give two practical ways in which Webster University is or can be taking advantage of the cloud concept.
The cloud concept has become popular due to its numerous benefits such as scalability, cost savings, flexibility, and ease of data access. The ability to have access to data and computing resources from anywhere and at any time has revolutionized the way companies conduct business operations. Webster University could take advantage of the cloud concept in several practical ways, such as by utilizing cloud-based collaboration tools to streamline communication and collaboration among staff and students (Li et al., 2011). Additionally, the university could migrate their data storage to cloud-based solutions to enable easy access and sharing of information among different departments and staff. With the adoption of cloud technologies, Webster University can leverage the benefits of the cloud to optimize their operations and enhance student learning experiences.
Conclusion
In conclusion, while both models deal with networking, there are some major differences. The OSI model is a theoretical approach to networking while the TCP/IP suite is a practical approach. The OSI model is used as a process for communication protocols to interact with each other while the TCP/IP suite is the protocol used for internet communication (Alani, 2014). Understanding these models can assist us in troubleshooting networking issues and ensuring effective communication within our IT infrastructure. It is important for management teams to have a basic understanding of these models in order to make informed decisions and successfully manage IT operations.
