DESIGN PROPOSAL

1.0 PHYSICAL NETWORK DESIGN This design implementation must be on LAN systems because it is located in within the same building that has no structured facilities that aid data transfer from one network to another. Use of proper network topology helps in structuring the network with advantages such as cost reduction and less power consumption. The network nodes and connection lines are supposed to be designed in such a way that it reduces complexity and utilizes the available space properly. Currently, there are both physical and logical network topologies [3]. The physical aspect is defined as the actual geometric ...

The types of Networks

A computer network describes a collection of computers and other devices. These computers and devices are interconnected by channels of communication which allow for the sharing of information and resources among the said devices that are interconnected. The classification of networks follows different characteristics such as the medium used for the transportation of data, the protocols of communication used, scale, topology, and the scope of an organization as stated by Akyildiz & Rudin (2013). The categories of networks, therefore, constitute; a local area network, a Wide Area Network, a Metropolitan Area Network, Wireless Local Area Network, System Area Network, and ...

In a bid to make their products more reliable, scalable and manageable, Microsoft protects its customers from the ever increasing cyber risks. The company has devised different methods that are specifically crafted to curb the known and unknown sources of cybercrimes and cyber security risks. This methods seek to protect customers’ information, hardware and software from attack by criminals and dangerous programs. The protective strategies are designed right from the development stages and are meant to be user friendly in order to be applicable by all customers and potential customers. The strategies include the User Account Control, System Updates, ...

In any given organization, it is of great importance to implement a good network for efficient utilization of resources. A good proposal of the company network will reduce the cost, increase the output of the network and will also be of great importance in the determination of the required resources and projection of the achievable output. A network that is well configured and designed will achieve all these. Based on given corporate network design architecture, a proposal on the resolution and the implementation of the various aspects of the network is discussed in this paper. The various deliverables of ...

Abstract

The privacy and confidentiality of information is a crucial factor for any organization dealing with large volumes of information. On the other hand, the development in technology, increase in the cases of cybercrimes, and the web-security issues that are common in almost every online platform, makes the need for database security concern for organizations that handle date. Currently, DBMS is one of the best tools for ensuring the safety of data, and this paper will review its use in database security. It will give a cognitive outline of how a company can use it, with the sole focus on ...

Literature Review

Abstract Innovations and modifications that produce cost reductions and enhance performance have driven the evolution of the classic solid rocket and the liquid bipropellant rocket into hybrid models that integrate the predominant solid and liquid model features into more sensical, more economical fabrications of design. The commercial spacecraft demands for aerospace propulsion have also evolved to include a market for environmentally sustainable hybrid rocket engines that has yet to fully mature to the Technology Readiness Level (TRL). Numerical modeling has been used as a tool to test the feasibility of new solid fuel types. ABS has been considered as ...

Personal Computer Purchasing Project

Personal Computer Purchasing Project. 1.0 Introduction: When purchasing a personal computer for home or business use, buyers are faced with a myriad of options to choose from in the market based on brands, technical specifications, pricing, quality, and reliability. In this case, it is important to conduct significant market research, read customer and technical reviews, and make your own comparison before deciding on the PC to buy. Some of the major considerations include the intended usage i.e. for home entertainment, business or gaming, etc. There are considerations to be made with regard to software such as operating systems and ...

A brake is a device that produces artificial resistance to the moving part of a machine to stop or slow down its motion. Any machine or its part that is in motion possesses kinetic energy. As per physical laws, energy cannot be destroyed; its form can only be transformed. The brake system converts the kinetic energy of the moving machine or part into thermal, potential or chemical energy. Brake systems are of various types utilized in different applications in industries, home appliances, vehicles, railway trains, and other sectors. This paper has focused on the brake systems used in vehicles, ...

RAID Hard Drive Configuration

“RAID which stands for Redundant Array of Inexpensive Disks” is nothing but a configuration where a logical unit of large storage space is created by putting together a number of different hard disk drives. The purpose of doing this is that it is very robust and can be fault free with higher efficiencies that a single or various individual hard disk drives. RAID is a very good and tested technology across platforms and geographies which help the users in a fast access of data with a lot of reliability. RAID is now commonly becoming a part of every network ...

Introduction

A database refers to a collection of organized information. The purpose of this configuration is to enable the easy access, management and updating of data. Databases can be grouped according to the content types they hold. They can be full-text, bibliographic databases and images. In the field of computing, databases get classified according to their approach in terms of organization. The relational database is the most common approach. It is a tabular database whereby data gets refined so as to be organized and accessed in multiple ways. Object-oriented programming databases are congruent with data defined in object subclasses and ...

Chemistry

2. The nano carrier needs to remain in suspension in H2O, PBS, human serum, etc. What type of polymer do you need to use to decorate the surface of the nanocarrier to achieve this goal? In order to maintain the nanocarrier in suspension in water, Phosphate-Buffered Saline (PBS), human serum a suitable solution a polymer is needed on its surface. The polymer used needs to accomplish three goals. The polymer needs to decorate the nanocarrier surface to enhance suspension and secondly, to prevent protein absorption. Another characteristic is that the polymer evades the immune system. PLGA poly(lactic-co-)glycolic ...
