Network Archutecture

You have been hired to upgrade a network of 50 computers currently connected to 10 Mbps hubs. This long-overdue upgrade is necessary because of poor network response time caused by a lot of collisions occurring during long file transfers between clients and servers. How do you recommend upgrading this network? What interconnecting devices will you use, and what benefit will you get from using these devices? Write a short memo describing the upgrade and, if possible, include a drawing of the new network.

In designing and building a payroll program for a large organization with offices spread across the country, which possesses quite a few changelings to overcome and must be done in a particular manner. Thus having the right application architecture is important where the design is concerned. Because the company has one large data center that each office connects to via a wide area network (WAN), hence the appropriate architecture for this solution would have to consist of a WAN diagram to be used in management of this project, along with system documentation, and information technology architecture documents to provide a visual representation of the network. A wide area networks (WANs) usually covers a large, physical area. And many WANs

Team “C” was hired by Riordan Manufacturing management to overhaul the security features currently employed by the company. Management outlined a comprehensive plan that included a complete hardware refresh, security best practices and end user training. Team “C” will devote resources to assess the physical and network security issues and concerns at each Riordan plant. Once those have been identified, Team “C” will identify the data security issues and concerns present at each Riordan plant. Finally, Team “C” will address web security issues and concerns present at each Riordan plant and recommend a way forward for the company.

Q:1. Briefly explain following designing requirments that are required when designing the hardware and software infrastructure :

Computer architecture is a set of rules that say how software and hardware interact to create a network or platform. In other words computer architecture is the design of the network base on the needs of the user, the system if it is there or needs to be built, and the technology that needs to go into the project. System design is all how all the hardware is set up while the instruction set architecture is the program language.

Produce a report that justifies the need for network managers to undertake routine performance management activities. Please ensure that your justification for these activities relates to reasons of efficiency and how they affect the quality of the service provided.

Are you staff on any other servers currently?: Yes, I currently own a server but would like to take a break to see how getting staff on another server would be.

Network Operating systems: A Network operating system is the software, which runs on the server. It allows the server to control functions within a network. This could include users, groups and security. Some examples of these operating systems are Windows, Linux and Mac OS.

Write a short explanation (two to three sentences) of each concept and be prepared to discuss it with the class.

A network diagram is a technique for showing activity sequencing of a project’s activities (Schwalbe 2006). Network diagram give information about logical sequences dependences among the various tasks.

“Specific connectivity” is used to prioritize the molecule to add to a growing network. As the network grows, IPA evaluates how much a new gene’s neighborhood overlaps the current network and selects the molecule that overlaps the most. “Overlap” is the number of molecules that are similar compared to the total number of molecules. “Specific connectivity” is computed by dividing the number of molecules found in the intersection of the neighborhood and the network by the number of molecules in their union If specific connectivity (SC) = (number of genes in intersection of the neighborhood and network) / (number of genes in union of the neighborhood and network) Then:

Here I want to discuss what is System analysis and design, when and where the concepts are used and how to overcome the problems using these concepts. The methodology of using characterizing the parts, structural engineering, interfaces and information for a framework to fulfil the decided necessities is said as system design. This course is helpful in developing the designing and analysing skills. Overall, system analysis and design is said as analysing and designing the different process.

In order to better understand the similarities and differences between software architecture and building architecture one needs to know what software is. According to "Software Engineering Institute" (2015), "The software architecture of a program

The interview session has been done by include an open-ended and closed-ended question which are related to the implemented project. Next, sampling technique is executed by system analyst who does evaluation to the current system or prototype. These processes give feedback in evaluation form that filled after tested the system. Lastly, observation is performed by using questionnaire form. According to Burch (1992), the questionnaire is analyzed and transform into structured form that easy to understand. After all information has been collected, structuring of system requirement takes place. It focused on development process modeling which perform “graphically representing the process, or actions, that capture, manipulate, store, and distribute data between a system and environment” (Hoffer, George, & Valacich, 2012, p. 182). In this step, Data flow diagram (DFD) is structured by system analyst using special tools and techniques to create a decision table. According to Hoffer, George and Valacich (2012), decision table is a “diagram of process logic where the logic is reasonably complicated” (p. 200). This table is useful to help system analyst to make a decision toward the project. Then all information’s gained from this phase are documented in System Analysis Report (SAR) that acts as a guideline or reference to the future system development project (Burch, 1992).

We are using different technology for the larger program or a project or we can say an application. This various technology needs to be arranged to recognize quality of the product. By using the software architecture we can easily recognize key scenario and identify important quality attribute like reliability or scalability (usability).
