Proposed Topology

In order to plan for the facility of the network, I am proposing a star network topology for the facilities networking. This kind of network infrastructure is considered expensive due to numerous network devices that ...

Topology refers to the way in which computer networks are connected. It is the interconnection configuration that is responsible for providing effective communication. It involves connecting devices, arranging nodes and cables (Rouse, 2016). There are different types of network topologies, and each of them has specific tasks. In this paper, the differences between the topologies will be discussed.

Bus Topology

In this kind of topology, all devices are connected to a common shared cable. The name of the cable is a bus. Thus, there is a way in which all devices are directly connected to each other in the network. For ...

Introduction

Active directory (AD) is a windows domain network or Network Operating (NOS) directory mainly designed for windows server 2003 and windows 2000. Active directory therefore is directory service, which catalog information stored in an organized manner allowing access to information in the directory matching their values and names. For example, a user trying to log into a computer in a client computer in the server domain of the network, active network aid access by verifying the back end user by matching a user password and the directory domain thereby determines whether you are a system administrator or a regular ...

You are required to simulate the behavior of a packet switching network inside the laboratory. The creation of a network will require using the packet and link editors; defining the collected statistics; and learning new Kernel procedures. Some other benefits that will be derived from the lab include learning the principles of model design; becoming familiar with the node and process models; learning how the node and process models function within a network model; carry out parametric studies of various statistics. The performance of a simple packet switching network is measured by the end-to-end delay experienced by traffic on ...

Computer Networks

When two or more processing are connected together either to share any resource like printer, data exchange or electronic communication, it is called a network. There are many different ways in which the computers and devices can be connected to each other in the network including cables, radio waves, infrared, satellites, etc (Tanenbaum 1). There are two possible types of networks; peer to peer and server based which is mostly called client-server network. In peer to peer network, computers are connected in a group for the purpose of sharing data/ information, and resources. There is no controller or a ...

Physical Network Design

Physical network design Network topology Business needs Assessing the school’s needs and building layout, it evident that two hundred and twelve computers are to be installed in the school’s network. The network will serve six computer labs, administration offices and two server rooms. On the network needed by the school, some of the computers will be servers and some will be clients used by students as well as guests. Based on the specifications provided, the school’s staff will have their own network, students will have their own network, and members of the public will have their ...

Executive summary

With the fast adoption of information systems in many organizations, there is a need to have healthcare information systems integrated in hospitals. This will improve the working of the hospital staff and will enhance the quality of services that will be offered by the staff in the hospitals. The process of integrating information systems to organizations requires a thorough understanding of what the information systems will solve. There is a need to understand the requirements of the organization and how the information system will bring efficiency. There is a need to understand the aligning of the business needs and that of the business. ...

Introduction

The term “cluster computing” and “grid computing” are used interchangeably when describing networked computers designed to run distributed applications in order to share resources. However, they are used to in describing the varied set of distributed computing with ambiguous solutions. Both cluster and grid computing are used simultaneously to improve the performance of the application. The both help in sharing available resources such as printers, scanners and speakers (Dongarra et al., 2004). Nonetheless, grid and cluster computing have different approaches in problem solving since they differ in terms of their infrastructure and technologies. Grid and cluster computing can be ...

Enterprise Application Integration (EAI) and its Features

Enterprise Application Integration (EAI) refers to the seamless incorporation of two or more enterprise computer applications to enable them operate as a single system using a combination of software, hardware, processes and standards (Goldstone Technologies Limited, n.d.). It facilitates the creation of a dynamic business environment by permitting organizations to integrate their business processes both internally, and externally with their partners. EAI developed in response to the progression in distributed computing and the emergence of open information systems. There are three models of integration of applications: presentation, data and functional integration (Kalyani, 2012). In these models, new software in integrated into the ...

A though assess of the network determines the best viable option to be adopted. The current network in use is not efficient in terms of topology, security, needs of the users ...

In this paper, I have chosen to write about the network configuration that is required in a book store. In such a business there are a good number of computers and other peripherals that are supposed to be interconnected. To come up with a good computer and other devices on the network, three major elements are dealt with. These are the network topology, the protocol and the internet connection. Among the three network topologies that are available: that is the star topology, bus topology and ring topology, star topology best fit this kind of network devices configuration because it is simple to ...

Security has become a big problem in today’s organizations setting. Intruders of al kinds have managed to successfully break into many companies’ web services as well as their networks. Several trials have been developed to curb the same from and secure companies’ infrastructural networks and exchange of information through secure channels, among these are firewall setups, encryption technology, and VPNs. Intrusion Detection is a new mechanism of instilling security in organizations’ networks. Application of this technique assists IT security manager to gather and utilize information resulting from recognized attacks and check if someone is attempting to break into your network ...

The Top-Down Approach

Network Architecture and Design: The Top-Down Approach

Network architecture and design are many times two separate stages in a network implementation project. McCabe (2007) identifies network architecture as a higher level concept of a network. He says that it focuses on more general relationships between the major components of a network. For example, "addressing and routing, network management, performance, and security." (p. 211). The design stage of the project normally starts after the higher level architectural plan has been approved. This is where the real detailed work starts and the nuts and bolts start to come together. In designing your network, ...
