software testing methodologies
Various program kinds that can be used in operating computers and other related devices are generally termed as software (Rouse, 2006). Software can be application software or system software. Application software are developed strategically for certain purpose and they directly fulfill the users interests. System software such as operating systems, support the whole functionality in the computers and other devices inclusive of the application software.
There are different ways in which software can be acquired or purchased once developed. Software is initially developed by a person or a company and put on the market where it is accessible for the public. In some cases, organizations develop their own software (in-house development) and it is not open to the public. In instances where software is available for purchase by the public, it can be either as shareware, liteware, freeware, open source or public domain software (Rouse, 2006). Shareware is software that intended for sale but this is after a free trial period, it offers the option of ‘try-before-you-use’ (Asp-software.org, 2014). Liteware is a form of shareware. It is software which is intended for sale once the trial period is complete, but in this case the trial period software has disabled capabilities.

word processing software
Microsoft word is a word processor designed by Microsoft for commercial purposes. It is a component of Microsoft Office suite of productivity software, but it is also available as a stand – alone software. It is mostly referred as MS word and can be used in both Windows and Macintosh platforms. Microsoft first launched it in 1983 and from since then many versions have been developed. Over the years, Microsoft has improved significantly with 1985 version being able to run on Macintosh operating system. Document creation features have been enhanced in the new versions such as bold, underline, italic and strike – through properties.
Quick part is one part of the word that will be using in my job. Quick part enable you to create and share professional- looking documents by combining a compressing set of writing tools with an easy to use interface. It is possible to quickly assemble documents from frequently used or pre-defined content such as disclaimer text.
In word processing, there are various features that help in saving time and also improving the quality of work. For instance, results – oriented interface presents the right tool when needed for easier formatting of documents. What this means is that you can spend more time writing but spend less time formatting the document. A new tri-panel review panel is another feature that allows one to quickly compare two versions of a document.

it project management review
There is significant difference between information technology (IT) strategy and information system (IS) strategy. A business that choses to include information technology in its daily activities requires that IT synchronize with the business’s strategy. Information technology deals with the identification of this synchronization. The synchronization creates a view in which the available IT resources are in line with the business needs. The IT strategy should serve the business needs and not the vice versa. This provides the direction in the creation of IT strategy by the managers. Business strategy differs in that it is outbound and looks towards meeting customer needs. The strategy is geared towards the market, with an aim to make sure that the services and products of the business are fit for the market. This means that business strategy is outbound and intends to align the business with the needs of the customer. This is unlike the IT strategy which is inbound and intends to align itself with the internal needs of the business.
IT strategy aims to help the business to acquire the best related technologies in order for the business to meet its needs and to execute the business strategy in a way that gives a competitive edge. In this regard, IT strategy is aimed at identifying the available technology for information management that a business can have, and to identify the IT type that would be useless to the organization. IT strategy should not be geared towards profitability, but it is geared towards efficiency and similar benefits. It is conclusive that business strategy effectiveness may be measured in a monetary terms, but the IT strategy is hard to measure in monetary terms since most of the benefits takes other different forms.

IT Investment and Strategy Jeopardy
The chances that IT in a business is highly advantages are put down in various documents. This is investing in information technology. The problem that lingers is the fact that there is difficulty in determining how much to put into information technology as an investment is difficult. The right information technology investment increases the competitiveness of the business

Biology is one of the divisions of science. It mainly deals with the study of living things which can be categorized into plants and animals. Learning biology is one of the most comforting things in school. This is because the learner deals with things that specifically surround and benefit him/her. The knowledge base of biology is determined by the level of education one gets to with one getting more knowledge through specification (Love and Glen 2003). Biology is a subject that’s interesting because of the prospect of learning about living things. Having a good knowledge base is important since they are of great use to humans hence necessitate an interest in studying them.
1. The natural resources available worldwide are moderately available. This is because there are some regions that these resources are very much available while in others they are not. A good example is the availability of water. We can see that there are some regions that have water in abundance while others are having trouble looking for water (Whitacre 2010).
It’s essential in sustaining all living things and systems.
They are important mostly for studying purposes.

linear and differential cryptography
This paper will discuss the linear and differential cryptographic analysis techniques. The linear cryptographic analysis is accredited to Mitsuru Matsui, and he first applied it to the FEAL cipher. Theoretically, it was developed for the DES encryption he introduced it at EUROCRYPT ‘93. Later he was practically successful in the cryptographic analysis of (DES) Data Encryption Standard. The differential cryptographic analysis is accredited to Adi Shamir and Eli Biham in the 1980s they presented it at CRYPTO ’90. They published several attacks against several hash functions and block ciphers, which included a theoretical weakness in DES encryption. Biham and Shamir noted that DES was unexpectedly resistant to their cryptographic analysis, since small modifications, in the algorithm, made it more vulnerable.
Both attacks at development targeted the DES encryption method, but the diverse applicability of both attacks on many block ciphers solidified the reputation of both cryptographic analysis methods taking into consideration the security of every block cipher. For instance, numerous candidates’ submitted ideas for the development of the Advanced Encryption Standard (AES) process were designed using procedures particularly targeted at preventing linear and differential cryptographic analysis. In terms of similarity both employ numerous pairs of plaintext or ciphertext, numerous input messages encrypted with a similar key and for every key the attacker has knowledge of the block value before and after encryption. They both rely on the approximation of the approximation of the internal actions of the encryption, which carries a minute but non-zero probability for similar inputs.
