...Most people who use computers are clueless to the internal ways that computers work. Here we will be talking a little about why a computer user might need to be familiar with things such as the binary system, Boolean operations, and the time it takes to transfer data. The average computer user is probably not aware that the actual operations of a computer are done with a binary system. Most of the time a typical computer user has no need to think about this aspect of computers, but every now and then the underlying binary nature will manifest itself. It’s more likely they will encounter a more compact variant of the binary system, called hexadecimal (or “hex” for short). Hex can come up on a Windows error message and the hex addresses may help pinpoint the source of trouble. Hex can also be used by spammers to hide their internet addresses. Another place where hex numbers commonly occur is in hypertext markup language (HTML) code where they are used to designate colors. Boolean Operators are simple words (AND, OR, NOT) used to combine or exclude keywords in a search, resulting in more focused and productive results. Using these operators can greatly reduce or expand the amount of records returned. They are useful in saving time by focusing searches for more ‘on-target’ results that are more appropriate to your needs. The AND operator narrows the search by requiring both terms to be in each item returned. If one term is contained in the document and the other is not, the item...

...Transfer Time 1 Transfer Time and File Size Transfer Time 2 Abstract Calculating Transfer Rate, Transfer Time and File size can be pretty difficult unless one has a basic knowledge of binary numbers and the different types of storage capacities that are out there. In order to figure out how fast a download will take there is some math that needs to be figured out and in this paper I will mention the way to conquer this task. Transfer Time 3 Transfer Time and File Size The very first step to understanding transfer time and file size is to first know that 1 byte is equal to 8 bits as well as what each component is exactly. A bit is defined as:” a single basic unit of information, used in connection with computers and electronic communication”. (Quote, n.d.) A byte is “pronounced ‘bite’, is the next size up basic unit of measurement for information storage, usually consisting of 8 bits”. (Quote, n.d.) The next set of terms that are used is: Kilo (kilobytes) equal to 1,000 bits stated in decimal form or 1,024 bytes stated in binary form. Then we have Mega (megabytes) equal to 1,000,000 decimal bits or 1,048,576 binary bits. Next is one of the bigger bytes and that is Giga (gigabytes) which is equal to 1,000,000,000 decimal bits or 1,073,741,824 binary bits. After figuring out the numbers to these complex bits of information, the next step is to understand the speed of transferring data. This is simply downloading information...

...currency bitcoin to increase the speed, and slash the price, of international money transfers, raising the prospect of a revolution in the $600bn annual global remittance market. Soaring rates of mobile phone use in developing countries are helping the entrepreneurs compete with more usual forms of money transfer in countries where remittance rates and fees are highest. Many of the world’s poorest people depend on money sent to them from friends and family abroad. According to World Bank figures for 2011, nearly half of Tajikistan’s GDP is derived from remittances, while in Liberia, Lesotho, Nepal and Haiti they account for more than a fifth of GDP. Entrepreneurs claim they are using bitcoin to give some of the world’s poorest people a better deal on the money they receive from abroad. The World Bank calculates the average fee on remittances at 8%, yet charges can be three times as high. A report from the Overseas Development Institute (published in April 2014 , said the benefits of remittance transfers “are lost in intermediation as a result of high charges. Africa’s diaspora pays 12% to send $200 – almost double the global average.” Bitcoin could also cut the time it takes to send remittances. BitPesa, a Kenyan mobile money transfer firm that launched in May, says its remittance transactions are “twice as fast and 75% cheaper” than competitors, because it uses bitcoin to transfer funds. Elizabeth Rossiello, BitPesa’s founder and CEO, said: “We’re looking to bring...

By Michael Kamoyo Chinhoyi University of Technology Lecturer: Department of Marketing mkamoyo@cut.ac.zw ; rumbi12@yahoo.co.uk Tel: 263 67 29442 Abstract better positioned to adopt and assimilate international trade related technology because they possess better technological capabilities in the form of The paper examines the preparedness of exporting and non-exporting SMEs in harnessing the technological opportunities availed by international trade. Using cross sectional data for 131 SMEs, a logistic regression analysis was done to ascertain the extent to which factors like, technical skills, networking, firm’s innovation system, especially research and development activities and international involvement influence the adaptation and assimilation of technology for productive efficiency. The result shows that labour used in exporting firms is 3.164 times more productivity than that in non-exporting firms, high import composition, good networking abilities. However, it was noted that there is no significant difference between exporting and non-exporting firms on Information Communication Technology (ICT) diffusion and R&D activities. It is recommended that for technology transfer to be relevant and useful to non-exporting firms there is need to strengthen their technological absorptive capacity by scaling up their networking...

We examine how M-Pesa is used as well as its economic impacts. Analyzing data from two waves of individual data on financial access in Kenya, we find that increased use of M-Pesa lowers the propensity of people to use informal savings mechanisms such as ROSCAS, but raises the probability of their being banked.

Flames behave differently under various conditions which include: the oxygen available, combustible material, orientation of surfaces, etc. this a complex phenomena which is influenced by multiple factors that includes ignition, heat release rate, flame spread and the generation of different products of combustion like carbon IV oxide and carbon II oxide. The research was performed by studying various sources in the library and in the internet and also performing experiments to simulate a real life situation. Introduction The Fire Problem The flammability of a material is a complex event which is influenced by multiple factors that includes ignition, heat release rate, flame spread and the generation of different products of combustion like carbon IV oxide and carbon II oxide. In order to better protect the people and property from risk posed by the unwanted fires, it become necessary to understands all these factors under different conditions. Babrauskas and Vytenis 1992 suggested that heat release rate is the main variable in fire hazard; but Kashiwagi and Ito argued effectively that, the flame spread over the surface...

Product Y is sold to Division C, which uses it as a component of Product Z. Product Z is also sold to customers outside of the Company. The intracompany pricing rule is that product are transferred between divisions as standard cost plus 10 percent return on inventories and fixed assets. Case Questions Question a: with transfer price calculated in Problem 1, is Division C better advised to maintain its price at $28 or follow competition in each of the instances above? Answer: Under possible competitive price $27.00 If company maintain the price at $28, the profit=(28-23.6) ×9,000=39,600 If company follow the possible competitive price at $27, the profit= (27-23.6) ×10,000=34,000 Under possible competitive price $26.00 If company maintain the price at $28, the profit=(28-23.6) ×7,000=30,800 If company follow the possible competitive price at $26, the profit= (26-23.6) ×10,000=24,000 Under possible competitive price $25.00 If company maintain the price at $28, the profit=(28-23.6) ×5,000=22,000 If company follow the possible competitive price at $25, the profit= (25-23.6) ×10,000=14,000 Under possible competitive...
