Information is a strategic and critical organization’s resource that takes a significant portion of the organization’s budget. In any organization, system security is crucial and sensitive to executive management (McGraw, 2006). Over the past years, many organizations have been failing due to a lack of appropriate and reliable security systems and software within their organizations.

The system that can be closely related to the workflow management system is the airline reservation system also known as the passenger service system (Ren, 2000). This system is used in airline companies where customers can access service, seek assistance, and book flights from any location as long as they have internet connectivity and they can access the online system.

DSDM (dynamic system development method) is a system development approach that acts as a framework for developing and maintaining software. This software development approach is mostly implemented in time-constrained environments where it involves the use of incremental prototyping in controlled project management (Stampleton, 2000).

Our prototypes will follow the popularly sued prototypes in the literature (Preece, 2002) (Scharge, 1996) (Walker, 2002). The prototype will reflect our idea of the implementation of the project. It will show main parts of the model that is required to implement the two suggested parts of the attendance system, self-checking in and receptionist aided checking in.

The United States sector of Veteran Affairs is the second biggest sector in the United States, and a government-run military veteran benefit system seeks to offer benefits to American veterans. Thousands of people run the system, and a lot of information is collected in the process of managing the system. Most of this information is vital and private and so it should be kept private at all times.

Scrum is a very well-known agile software development methodology. Scrum software development starts with the customer’s story. This story can be anything which a customer uses to describe their requirements. For instance, the end-user needs to add a new contact in the address book, in order that he can interact with the person in the future by email or postal mail. 

Scrum is an example of an incremental and iterative agile software method, used for purposes of managing and developing software applications, products and projects. The focus of scrum methodology is on its holistic and flexible product development strategy, where the designing team works as a group or unit for purposes of reaching a common objective/goal.  

Web 3.0 also known as the semantic web has this notion that we should add new types of mark up to data so as to make it have more meaning to the computers. Web 3.0 seeks to transform the web environment from a catalog into a guiding tool through the introduction of new features that were never found in Web 1.0 and Web 2.0.

Certainly, information and particularly electronic information plays a key role in the developmental aspects of a nation (Sears & Moody, 2001). This is especially so because adequate access to electronic information can benefit the citizens of a particular country in as much as it benefits the government in place (Ushahidi, 2014).

The specific port used should be dedicated only to the listening connection for a new request. Server socket is a socket associated with a specific port, and when a connection request arrives on this socket from the client-side, the client and the server establish a connection. The connection is established as follows:

The system has a crash dump sector which if the system happens to crash will record the current activities that led to the crash and also store the default of the system thereby allowing for a reboot and restoration of the system, though any information being keyed in or processes taking place during the crash time will have to be done again.

However the capacity and memory of human mind is limited on how many information it can process within a given time. The introduction of high computing information for instructional designs improves the cognitive theories. The use of animation principle

The history of information security stretches back to ancient periods, and it began with the creation of a bureaucracy in the administration competition. Aspects like interference of the encrypted messages drew much attention during the First World War, whereas other important aspects have remained considerably not covered.

Information technology is often applied in virtually all the organizations, be they profit or non-profit. It works well in a well-designed framework called IT infrastructure, which includes computer networks, database management, computers, information centres and systems that regulate data transmission.

Analysis of these security vulnerabilities calls for the need to safeguard the network against unauthorized access and cyber attacks proactively. Security mechanisms employed to safeguard networks against attacks include Wired Equivalent Privacy, 802.11i (WPA), and WI-FI protected Access (WPA).

Biometric technology has been used in offering better security and convenience when controlling access to facilities as well as other tangible resources. Moreover, the application of biometrics in “time and attendance” applications offer convenience to employees and provide a better way of protecting the employer from fraud.

Telecommuting is a situation in which workers operate from a virtual office. Meaning, under this arrangement, an employee does not need to go to their officers but can perform their duties right from the comfort of their homes by just using the internet to perform their tasks. This is one of the major benefits of the internet to individual employees.

"Total quality management aims at realizing quality” (Sven, 2007). This management aspect cannot be under looked in the daycare business. The quality of the services to children needs reengineering regularly and the systems need regular updating and close relation. This will aid in keeping a good system that is ready for use at any time by the organization.

Erickson, Lyytinen & Siau (2005) associates agility with concepts like nimbleness, suppleness, dexterity, quickness, liveliness, or alertness and postulates agility to mean to strip away as much of the heaviness as possible that had been previously associated with the traditional software development methodologies in a bid to promote quick response to changing environment as well as the changes in the user requirements, accelerated project deadlines and the like. 

The lives of many individuals have been transformed through online encounters. Online dating enables individuals to know and interact with different people across the globe and share their common interests. More so, it helps those individuals who are nervous in the presence of the opposite sex to easily interact with others without meeting them personally.

Advanced Research recognizes the significance of testing its security architecture for exploits and vulnerabilities before attackers take advantage of them and cause serious losses. The security testing software presented in this proposal is referred to developed by Rapid7- a security management company. It presents a package of software solutions.

The Sprint Spark technology is basically an enhancement of the current standard LTE network that delivers a fair quick Internet access when using a mobile phone, which is at the same level with a broadband connection. This Sprint network new evolution is part of the Network Vision, which involved redesigning the cell towers it uses and other important aspects of the network operations (Costa, 2014).

The discussion which has been conducted in this essay focuses on outlining a range of issues concerning crime and how information technology may be utilized to engage in delinquent and illegal activities. However, it should be noted that a comprehensive analysis of a range of issues represents that it is important to distinguish between the legality of the scenario.

There exist differences between a library and an archive, though these two are important sources of information. An archive may have a library as its part, or an archive can be a department in a library. The main differences between archives and libraries lie in the types of material they hold, the way people access this material, and their role.

Total Information Awareness (TIA), a proposal by the Defense Advanced Research projects (DARPA) that is reliant on data mining and tracking information will be discussed in terms of the regulations and ethical concerns involved. The Global Positioning System (GPS) is a more advanced tool in terms of reporting the location of an object. The GPS tracker has a receiver that determines the position of an object. 

According to Flitter (2014), a cyber-related attack on Bitcoin is called a distributed denial-of service attack. The attacker uses it to send many illegal transactions to companies that trade using Bitcoin. The Spamming of online storage of Bitcoins can force the companies to stop the transaction. . Such efforts must be made by companies so as to determine the real transaction.

Mobile or cell phones are used in sending, receiving messages, emails, photos, videos, also making, and receiving calls. Cell phones are also used to access the world wide web, listen to music, play games, receive news from different radio networks and also use global positioning systems (GPS) among other many functions.

Privacy is another benefit of the deep web that most business organizations enjoy (Olsen, 2005). This privacy allows them to conduct business, keep their financial record and company records where nobody can access them. Furthermore, this privacy can assist organizations to monitor competition from rival companies without being noticed. 

Microsoft Inc. first announced the idea of developing Windows in 1983. The Microsoft windows that were a GUI (graphical user interface) targeted Microsoft's operating system (MS-DOS). The Microsoft windows product line has since changed from a simple GUI to the integrated and modern operating system to form two-family operating designs, each characterized by its default filing system and codebases.

However, a new type of database known as Apache and Hadoop have been developed to challenge these databases (“Business Intelligence-BI”). In an effort to have a more integrated approach in open-source software, data locality and packages have been a huge functionality. Another basis of the functionality is the fact that uses a distributed file system.

Both government and private sector have been a victim. Despite extensive awareness of the impact of cyber crime, the attacks seem to be more rampant. According to a study conducted, a company in US uses $ 1.5 million to $ 36.5 million each year on cyber crime. Companies considered experienced 72 successful attacks per week (Ponemon Institute August 2011).

The paper intends to delve into how novel systems would adequately cater to the needs of the service provider in terms of customer base integration and scheduling and payment platforms. The focus will be on the implementation of an effective electronic payment system and the cost benefits to be gained through this process.

The document will explain the features and purpose of the system, its interfaces, the functionalities of the system, the constraints under which the system must operate and the methods in which the system will interact with external entities.

Computer systems have also brought about the construction of customized software applications to meet particular organizational needs. An example of such applications is customer relationship management (CRM) software intended to address clients' concerns in a well-timed manner while reducing the workforce required in a business' customer service section.

This application, which is able to generate two random matrices X (A, B) and Y (B, C), and allow basic matric operations such as multiplication has been done using C++ using, first, the Strassen’s algorithm, and a sequential method, resulting in matrix Z (A, C). Strassen’s Algorithm is an important tool that can be successfully used in the multiplication of two random matrices.

Dr. Connor and Fintan MacCormack created specific Deposition Lamination (SDL) or paper 3-D printing in 2003. Dr. MacCormack initially found 3-D printing in 1986, when he was an auxiliary understudy in Ireland viewing a BBC exceptional casting. The innovation caught his creative ability in the same way that bikes, rockets, PCs and space travel now had.

The real-time aspect of the Bro system helps to ensure that the damage that can be caused by the intruders are minimized since, with the real-time detection of the possible intrusion, the intrusions can be reacted to and stopped before they have caused any meaningful damage to the network (Paxson, 1999).

Ethical issues also influence the level of forensic investigation of the computer crime scenes (Al-Omari, Deokar, El-Gayar, Walters, & Aleassa, 2013). In most cases, companies hire specialized consultants to investigate the information security issues though the personnel rarely understand the ethical concerns that might prevent them from fully investigating the crime scenes.

The NSA cracks the programs in use and can now monitor whatever goes on within the country (Shi, 2007). This hacking is done in the name of ensuring national security, although it faces a lot of rebellion from the public. Modern technology has changed the way in which criminal activities are carried out.

The research process will be done in three key stages; data collection, data analysis, and data presentation.  Data will be collected through interviews and data mining. Data mining will study the literature concerning the elderly and internet technology. Online journals will be used for data collection.

At that point utilize a 3D printer to print the heart. This guided the specialists who repaired the child's heart with stand out operation, instead of settle on choices by ceasing the heart and looking inside. How enchantment 3D printing innovation is! Clearly 3D printing innovation gives a successful answer for the therapeutic business, and it was effective to spare an existence.

In terms of regions, the region with the highest overall rate of software piracy is Asia pacific with 62 percent and the region with the lowest rate of software piracy in North America with 19 percent. The three countries with the highest software piracy are Venezuela, Indonesia, and China, the rate of software piracy is 88, 86, and 77 percent respectively.

The results of regression analysis show that the four factors together predict VOD booking significantly, F=105.635, p < .001 as illustrated in Table 1. The Second regression analysis results indicate that the three factors (Price, genre, tweets) together predict VOD booking, F=80.389, p < .001 as illustrated in Table 2. 

An endless debate has been going on whether the internet should be censored. This is because the internet has been accused of harboring and a platform of ‘offensive material.’ It is claimed that children are capable of watching inappropriate material like pornography from the internet, hence the need to censor the internet. 

Operating System (OS) is software that is used in computers to manage the hardware and the software so that they can work interactively without causing a halt to the computer. It is obvious that without an Operating System in the computer the software programs that are installed on the computer would make no sense.

The operating system can secure the information put into a computer where unauthorized users cannot access it. There are various operating system categories, including multi-user, multiprocessing, multi-reading, real-time, and multitasking. Operating systems are usually installed in computers by professions who follow certain procedures, as discussed in the paper.

The information systems form a whole project for a particular organization. Tools such as CASE tools are used in project management. Developers are required to come up with sophisticated software to run the systems. The software has to be tested before they are implemented. In addition, the software has to be checked and updated every now and then.

The most important task in the designing of a system is the recognition of the problem. It entails looking at the current operations and system and analyze if it meets the organization's demand. The analyst, therefore, surveys by gathering all the required information for the designing of the program. It will also give a picture of the system.

Within the context of the basic system, the Signal to Noise Ratio, or SNR, of the sub-band coder is as its maximum value based on the energy level of the band. With adaptive bit allocation, the system finds the energy of every specific band immediately after H1(z) and H2(z). The purpose of this is for the system to be able to automatically compute the best possible SNR.

The “Mom for Marijuana” website is less accurate and trustworthy than the website of the National Institute on Drug Abuse. The point is that the first website presents information very unilaterally, using some false facts and unbelievable researches to support their point, when the second website operates real facts and corroborates them, referring to real researches and scientific experiments.
